Purpose: To investigate predictive factors for redislocation in patients with recurrent intraocular lens (IOL) dislocation after secondary scleral-fixated IOL (SF IOL) surgery. Setting: 2 tertiary referral hospitals. Design: Retrospective case series. Methods: Patients undergoing SF IOL surgery were grouped into redislocation and no-redislocation groups. Medical records of consecutive patients who underwent SF IOL surgery between June 2014 and December 2019 at 2 tertiary referral centers were reviewed. Data regarding patient demographics, treatment factors, anatomical and functional outcomes, and postoperative complications were recorded. Results: 237 eyes of 225 patients (169 [75.1%] men) were included. The redislocation group was more likely to have a younger mean age at the initial SF IOL surgery (redislocation vs noredislocation, 55.4 vs 62.0 years, respectively; P = .008), have a prior history of a previous suture break (23 eyes, 52.3% vs 1 eye, 0.5%; P < .001), and have undergone the initial SF IOL surgery using <1 mm-sized side-port incisions (17 eyes, 38.6% vs 32 eyes, 16.5%; P = .002) than was the no-redislocation group. In addition, the redislocation group had a higher occurrence of complications (P < .001). Multivariate regression revealed that younger age, left eye involvement, aphakic status before the surgery, unremarkable primary IOL dislocation cause, need for ocular hypertension treatment and glaucoma surgery, and no large incision during the initial surgery were significantly (all P < .05) associated with redislocation. Conclusions: Younger age, left eye involvement, postoperative complications such as ocular hypertension and glaucoma, and techniques without large incisions increase the risk of redislocation. Conversely, lower risk factors include unremarkable surgery causes and a history of aphakic conditions. [ABSTRACT FROM AUTHOR]

Background: Frailty is independently associated with adverse patient outcomes after surgery. The current standards of postoperative care rarely consider frailty status. Local Problem: There was no standardized protocol to optimize specialized postoperative care for frail patients at an academic medical center. Methods: A quasi-experimental pre-/postimplementation study design, using the Reach, Effectiveness, Adoption, Implementation, Maintenance implementation framework, was utilized. Interventions: A frailty-specific postoperative order set (FPOS) was developed, including tailored nursing care, activity levels, and nutritional goals. Results: There were significant improvements in nurse's self-reported familiarity with frailty (P = .003) and FPOS awareness (P < .001). The number of orders for delirium prevention, elimination, nutrition, sleep promotion, and sensory support increased (P < .001). Conclusions: Implementing an FPOS showed improvements in nurse frailty knowledge, awareness, and order set utilization. [ABSTRACT FROM AUTHOR]

Objective. The aim of this study was to provide benchmarks for the rates of complications by type of surgery performed. Study Design. Prospective multicenter database. Background. We have previously examined overall construct survival and complication rates for ASD surgery. However, the relationship between type of surgery and construct survival warrants more detailed assessment. Materials and Methods. Eight surgical scenarios were defined based on the levels treated, previous fusion status [primary (P) vs. revision (R)], and three-column osteotomy use (3CO): short lumbar fusion, LT-pelvis with 5 to 12 levels treated (P, R, or 3CO), UT-pelvis with 13 levels treated (P, R, or 3CO), and thoracic to lumbar fusion without pelvic fixation, representing 92.4% of the case in the cohort. Complication rates for each type were calculated and Kaplan-Meier curves with multivariate Cox regression analysis was used to evaluate the effect of the case characteristics on construct survival rate, while controlling for patient profile. Results. A total of 1073 of 1494 patients eligible for 2-year follow-up (71.8%) were captured. Survival curves for major complications (with or without reoperation), while controlling for demographics differed significantly among surgical types (P < 0.001). Fusion procedures short of the pelvis had the best survival rate, while UT-pelvis with 3CO had the worst survival rate. Longer fusions and more invasive operations were associated with lower 2-year complication-free survival, however, there were no significant associations between type of surgery and renal, cardiac, infection, wound, gastrointestinal, pulmonary, implant malposition, or neurological complications (all P > 0.5). Conclusions. This study suggests that there is an inherent increased risk of complication for some types of ASD surgery independent of patient profile. The results of this paper can be used to produce a surgery-adjusted benchmark for ASD surgery with regard to complications and survival. Such a tool can have very impactful applications for surgical decision-making and more informed patient counseling. Level of Evidence. Level III. [ABSTRACT FROM AUTHOR]

Background The modified Dunn procedure, which is based on the development of an extended retinacular flap containing the blood supply for the femoral head, allows anatomic reestablishment in patients with moderate to severe slipped capital femoral epiphysis (SCFE). Some controversy exists regarding the short-term to midterm risk of avascular necrosis (AVN) and other complications resulting from the surgical technique. Questions/purposes (1) What percentage of patients treated with an extended retinacular flap during the modified Dunn procedure for SCFE with a moderate (slip angle from 30° to 60°) or severe slip (slip angle equal or greater than 60°) develop symptomatic AVN, and what percentage underwent further surgery or had other complications? (2) What femoral head-neck alignment and position parameters relative to the greater trochanter are achieved after surgery? (3) Can we identify radiographic signs of osteoarthritis at a minimum of 4 years after surgery? Methods Between January 2006 and December 2018, we treated 61 patients for SCFE. During this time, we generally used the modified Dunn procedure when the slip angle was ≥ 30°. Based on this indication, the modified Dunn procedure was performed in 37 patients (41 hips) during that time period, and those patients were potentially eligible for this retrospective study. Because bilateral hips in the same patient are not statistically independent, for our analyses, we analyzed only the hip with the longer follow-up time. Of those who remained, 11% (4) were lost before the minimum study follow-up of 48 months or had incomplete datasets, leaving 89% (33) for analysis here at a median follow-up of 80 months (range 49 to 208 months). Periacetabular osteotomy or subtrochanteric rotational femoral osteotomy was added under the same anaesthesia time in 33% (11 patients). We added periacetabular osteotomy in 24% (8) when intraoperative anterior instability was present in external rotation. A femoral rotational osteotomy was added in 9% (3) when posterior instability was present in flexion and internal rotation. The mean ± standard deviation age at the time of surgery was 13 ± 1 years, and 33% (11 of 33) of patients were female. The mean slip angle was 51° ± 16°, and 15% (5) of hips had unstable slips, defined as an inability to walk with or without crutches. We documented chronic presentations in 82% (27) of patients, acute and chronic in 12% (4), and acute in 6% (2). The rate of symptomatic AVN was determined by reviewing all radiographs obtained at the latest follow-up interval. Further surgery and other complications were assessed through an electronic medical record review. Radiographic morphologic parameters were measured before surgery and at a minimum follow-up of 4 years by two senior orthopaedic surgeons. Radiographs obtained at the latest follow-up visit were also screened for signs of osteoarthritis by the same surgeons. Results At the latest follow-up, 3% (1 patient) of patients developed symptomatic AVN and underwent further surgery and 3% (1) underwent revision surgery for screw breakage after a high-energy fall. Postoperatively, the alpha angle was restored to 39° ± 6°, the anterior head-neck offset was restored to 8 ± 3 mm, the neck-shaft angle was 136° ± 6°, and the presence of a positive Klein line decreased from 64% (21 hips) to 0% (0 hips). No patients showed radiographic signs of osteoarthritis at the minimum follow-up of 4 years. Conclusion In this series, the modified Dunn procedure in moderate and severe slips was a reproducible procedure, and few patients developed symptomatic AVN or experienced other complications. Hip morphology was restored, but a longer follow-up duration and a detailed analysis of the results from other centers is warranted to assess the possible long-term risk of progression to AVN or osteoarthritis. Level of Evidence Level IV, therapeutic study. [ABSTRACT FROM AUTHOR]

Purpose: To compare the rates of intraoperative complications, cystoid macular edema (CME), and visual outcomes in eyes that underwent combined phacovitrectomy (Phaco-PPV) with those with stand-alone phacoemulsification. Setting: A multicenter database study across 8 ophthalmology departments in the United Kingdom. Design: Retrospective, nonrandomized, multicenter comparative study. Methods: We extracted data for patients who underwent Phaco- PPV and stand-alone phacoemulsification from January 2000 through May 2015. The primary study outcomes were the rates of intraoperative complications and CME postoperatively. Results: The study included 2222 eyes in the combined Phaco-PPV group and 112 689 in the stand-alone phacoemulsification group. The combined Phaco-PPV group had a higher incidence of posterior capsule rupture (2.7% vs 1.7%), dropped lens fragments (0.5% vs 0.2%), suprachoroidal hemorrhage (0.4% vs 0.1%), and CME (3.6 vs 1.1%) (P < .001). The mean preoperative visual acuity (VA) was lower in the combined Phaco-PPV group, with a mean VA of 0.98 vs 0.68 logMAR (Snellen ~20/200 vs 20/100) in the stand-alone phacoemulsification group (P < .001). VA at 24 weeks was lower in the combined Phaco-PPV group (mean VA 0.67 vs 0.22 logMAR (Snellen ~20/100 vs 20/32), P < .001). Conclusions: Combined Phaco-PPV had higher rates of intraoperative complications and CME, along with a lower postoperative VA, when compared with stand-alone phacoemulsification surgery.

Study Design. Retrospective cohort study. Objective. This study compares reoperation rates and complications following single-level anterior lumbar interbody fusion (ALIF)/lateral lumbar interbody fusion (LLIF) and transforaminal lumbar interbody fusion (TLIF)/posterior lumbar interbody fusion (PLIF). Summary of Background Data. ALIF, LLIF, TLIF, and PLIF are widely used for degenerative disc disease. Lumbar interbody fusions have high rates of reoperation, primarily related to adjacent segment pathology and pseudarthrosis. Materials and Methods. The PearlDiver database was queried for patients (2010-2021) who had single-level ALIF/LLIF or TLIF/PLIF with same-day, single-level posterior instrumentation. ALIF/LLIF were combined, and similarly, TLIF/PLIF were combined, given how these operations are indistinguishable from Current Procedural Terminology coding. All patients were followed for ≥ 2 years and excluded if they had spinal traumas, fractures, infections, or neoplasms before surgery. The two cohorts, ALIF/LLIF and TLIF/PLIF, were matched 1:1 based on age, sex, Elixhausercomorbidity index, smoking status, and diabetes. The primary outcome was the incidence of all-cause subsequent lumbar operations. Secondary outcomes included 90-day surgical complications. Results. After 1:1 matching, each cohort contained 14,070 patients. All-cause subsequent lumbar operations were nearly identical at five-year follow-up (9.4% ALIF/LLIF vs. 9.5% TLIF/PLIF, P=0.91). Survival analysis using all-cause subsequent lumbar operations as the endpoint showed an equivalent 10-year survival rate of 86.0% (95%CI: 85.2-86.8). Within 90 days, TLIF/PLIF had more infections (1.3% vs. 1.7%, P=0.007) and dural injuries (0.2% vs. 0.4%, P=0.001). There was no difference in wound dehiscence, hardware complications, or medical complications. Conclusion. As utilized in real-world clinical practice, singlelevel anterolateral versus posterior approaches for interbody fusion have no effect on long-term reoperation rates. [ABSTRACT FROM AUTHOR]

Study Design. Retrospective analysis of prospectively collected data. Objective. Evaluate the impact of correcting normative segmental lordosis values on postoperative outcomes. Background. Restoring lumbar lordosis magnitude is crucial in adult spinal deformity surgery, but the optimal location and segmental distribution remain unclear. Patients and Methods. Patients were grouped based on offset to normative segmental lordosis values, extracted from recent publications. Matched patients were within 10% of the cohort's mean offset, less than or over 10% were undercorrected and overcorrected. Surgical technique, patient-reported outcome measures, and surgical complications were compared across groups at baseline and two years. Results. In total, 510 patients with a mean age of 64.6, a mean Charlson comorbidity index 2.08, and a mean follow-up of 25 months. L4-5 was least likely to be matched (19.1%), while L4-S1 was the most likely (24.3%). More patients were overcorrected at proximal levels (T10-L2; undercorrected, U: 32.2% vs. matched, M: 21.7% vs. overcorrected, O: 46.1%) and undercorrected at distal levels (L4-S1: U: 39.0% vs. M: 24.3% vs. O: 36.8%). Postoperative Oswestry disability index was comparable across correction groups at all spinal levels except at L4-S1 and T10-L2/L4-S1, where overcorrected patients and matched were better than undercorrected (U: 32.1 vs. M: 25.4 vs. O: 26.5, P=0.005; U: 36.2 vs. M: 24.2 vs. O: 26.8, P=0.001; respectively). Patients overcorrected at T10-L2 experienced higher rates of proximal junctional failure (U: 16.0% vs. M: 15.6% vs. O: 32.8%, P<0.001) and had greater posterior inclination of the upper instrumented vertebrae (U: -9.2±9.4° vs. M: -9.6±9.1° vs. O: -12.2±10.0°, P<0.001), whereas undercorrection at these levels led to higher rates of revision for implant failure (U: 14.2% vs. M: 7.3% vs. O: 6.4%, P=0.025). Conclusions. Patients undergoing fusion for adult spinal deformity suffer higher rates of proximal junctional failure with overcorrection and increased rates of implant failure with undercorrection based on normative segmental lordosis.

BACKGROUND: Improving the quality of care is a priority for health systems to obtain better care and reduce costs. One of the tools for measuring quality is benchmarking (BM). We presented a 1- country prospective study of distal pancreatectomies (DPs) and determined BM. STUDY DESIGN: Prospective, multicenter, observational snapshot study of DP carried out at Spanish hepatopancreatobiliary centers for a year (February 1, 2022, to January 31, 2023). Hepatopancreatobiliary centers were defined as high volume if they performed more than 10 DPs per year. Inclusion criteria include any scheduled DP for any diagnosis and age older than 18 years. The low-risk group was defined following the criteria given by Durin and colleagues and major complications as Clavien-Dindo ≥III. RESULTS: A total of 313 patients from 42 centers and 46.6% from high-volume centers were included. Median DP by center was 7 (interquartile range 5 to 10), median age was 65 years (interquartile range 55 to 74), and 53.4% were female. The surgical approach was minimally invasive in 69.3%. Major complications were 21.1%. Postoperative pancreatic fistula grade B/C rate was 20.1%, and 90-day mortality was 1.6%. One hundred forty-three patients were in low-risk group (43.8%). Compared with previous BM data, an increasing MIS rate and fewer hospital stay were obtained. CONCLUSIONS: We present the first determination of DP-BM in a prospective series, obtaining similar results to the previous ones, but our BM values include a shorter hospital stay and a higher percentage of minimally invasive surgery probably related to Enhanced Recovery after Surgery protocols and prospective data collection. BM is a multiparameter valuable tool for reporting outcomes, comparing centers, and identifying the points to improve surgical care. [ABSTRACT FROM AUTHOR]

BACKGROUND: The direct association between procedure risk and outcomes in elderly patients who undergo emergency general surgery (EGS) has not been analyzed. Studies only highlight the importance of frailty. A comprehensive analysis of relevant risk factors and their association with outcomes in elderly patients who undergo EGS is lacking. We hypothesized that procedure risk has a stronger association with relevant outcomes in elderly patients who undergo EGS compared with frailty. STUDY DESIGN: Elderly patients (age >65 years) undergoing EGS operative procedures were identified in the NSQIP database (2018 to 2020) and stratified based on the presence of frailty calculated by the Modified 5-Item Frailty Index (mFI-5; mFI 0 nonfrail, mFI 1 to 2 frail, and mFI ≥3 severely frail) and based on procedure risk. Multivariable regression models and receiving operative curve analysis were used to determine risk factors associated with outcomes. RESULTS: A total of 59,633 elderly patients who underwent EGS were classified into nonfrail (17,496; 29.3%), frail (39,588; 66.4%), and severely frail (2,549; 4.3%). There were 25,157 patients in the low-risk procedure group and 34,476 in the high-risk group. Frailty and procedure risk were associated with increased mortality, complications, failure to rescue, and readmissions. Differences in outcomes were greater when patients were stratified according to procedure risk compared with frailty stratification alone. Procedure risk had a stronger association with relevant outcomes in elderly patients who underwent EGS compared with frailty. CONCLUSIONS: Assessing frailty in the population of elderly patients who undergo EGS without adjusting for the type of procedure or procedure risk ultimately presents an incomplete representation of how frailty impacts patient-related outcomes.

Older adults often present with multiple comorbidities and face significant postoperative complications. This study aimed to describe the role of Nurse Practitioner (NP)-led orthogeriatric services in managing hip fracture patients. We conducted a review of health records of older adults with hip and proximal femoral fractures between July 2017 and June 2018, presenting descriptive statistics on patient characteristics, surgical outcomes, and the involvement of orthogeriatric services. A total of 197 participants were included, with a majority being female (n = 132; 67.0%). Most patients (53.8%; n = 106) had between five and nine pre-existing conditions. Among the 192 patients who underwent surgery, 69.8% (n = 134) experienced up to four surgical complications. The Nurse Practitioner provided care to 89.1% (n = 163) of the patients within the orthogeriatric service, with half of the patients (n = 82) requiring at least five NP interventions to manage complex pre- and postoperative needs. Refining the NP-led model could potentially help reduce the burden on physicians and surgeons in treating complex medical conditions, especially in settings where geriatricians may not be readily available.

Study Design. Asymptomatic Multi-Ethnic Alignment Normative Study (MEANS) cohort: cross-sectional, multicenter. Symptomatic cohort: retrospective, multisurgeon, single-center. Objective. To assess the association of odontoid-coronal vertical axis (OD-CVA) and orbital-coronal vertical axis (ORB-CVA) with radiographic parameters, patient-reported outcomes, and clinical outcomes. Summary of Background Data. Previous literature studied the OD-CVA in an asymptomatic cohort and ORB-CVA in a symptomatic cohort, demonstrating their correlations with radiographic parameters and ORB-CVA with outcomes. Materials and Methods. A total of 468 asymptomatic adult participants were prospectively enrolled in the MEANS cohort. 174 symptomatic patients with adult spinal deformity with = 6 fused levels and 2-year follow-ups were retrospectively enrolled in the symptomatic cohort. The association between OD-CVA and ORB-CVA, and radiographic parameters, perioperative variables, PROs, and outcomes were analyzed. Pearson correlation was used to assess correlation and logistic regression odds of outcomes. Results. In the MEANS cohort, the ORB-CVA correlated with C7-CVA (r = 0.58) and OD-CVA (r = 0.74). In the symptomatic cohort, preoperative ORB-CVA correlated better with leg length discrepancy; r = 0.17, P = 0.029), whereas preoperative OD-CVA correlated better with C7-CVA (r = 0.90, P < 0.001). Postoperative ORB-CVA correlated with postoperative C7-CVA (r = 0.66, P < 0.001), and postoperative OD-CVA correlated strongly with postoperative C7-CVA (r = 0.81, P < 0.001). Both preoperative OD-CVA (r = 0.199) and ORB-CVA (r = 0.208) correlated with the preoperative Oswestry Disability Index. ORB-CVA correlated better than OD-CVA in the preoperative Scoliosis Research Society-22r pain category but worse in total and other subcategories. Preoperative ORB-CVA was associated with increased odds of intraoperative complication (odds ratio = 1.28, 1.01-1.22), like OD-CVA (odds ratio = 1.30, 1.12-1.53). Neither preoperative ORB-CVA nor OD-CVA was associated with reoperations and readmissions after multivariate analysis. Preoperative OD-ORB mismatch >1.5 cm was not associated with increased odds of intraoperative and postoperative complications, reoperations, or readmissions. Conclusion. ORB-CVA and OD-CVA correlated with radiographic parameters, patient-reported outcomes, and intraoperative complications. ORB-CVA and OD-CVA can be used interchangeably as cranial coronal parameters in adult spinal deformity surgery. [ABSTRACT FROM AUTHOR]

INTRODUCTION: Patients with ulcerative colitis (UC) receiving immunosuppressive drugs are at substantial risk of colectomy. We aimed to assess the risk of postoperative complications of tofacitinib exposure before colectomy in comparison with biologics. METHODS: A multicenter, retrospective, observational study was conducted in patients with UC who underwent total colectomy for medically refractory disease, exposed to tofacitinib or a biologic before surgery. Primary outcome was the occurrence of any complication within 30 (early) and 90 (late) days after surgery. Secondary outcomes were the occurrence of infections, sepsis, surgical site complications, venous thromboembolic events (VTE), hospital readmissions, and redo surgery within the same timepoints. RESULTS: Three hundred one patients (64 tofacitinib, 162 anti-tumor necrosis factor-α agents, 54 vedolizumab, and 21 ustekinumab) were included. No significant differences were reported in any outcome, except for a higher rate of early VTE with anti-tumor necrosis factor-α agents (P = 0.047) and of late VTE with vedolizumab (P = 0.03). In the multivariate analysis, drug class was not associated with a higher risk of any early and late complications. Urgent colectomy increased the risk of any early (odds ratio [OR] 1.92, 95% confidence interval [CI] 1.06-3.48) complications, early hospital readmission (OR 4.79, 95% CI 1.12-20.58), and early redo surgery (OR 7.49, 95% CI 1.17-47.85). A high steroid dose increased the risk of any early complications (OR 1.96, 95% CI 1.08-3.57), early surgical site complications (OR 2.03, 95% CI 1.01-4.09), and early redo surgery (OR 7.52, 95% CI 1.42-39.82). Laparoscopic surgery decreased the risk of any early complications (OR 0.54, 95% CI 0.29-1.00), early infections (OR 0.39, 95% CI 0.18-0.85), and late hospital readmissions (OR 0.34, 95% CI 0.12-1.00). DISCUSSION: Preoperative tofacitinib treatment demonstrated a postoperative safety profile comparable with biologics in patients with UC undergoing colectomy. [ABSTRACT FROM AUTHOR]

BACKGROUND: Laparoscopic surgery remains the mainstay of treating foregut pathologies. Several studies have shown improved outcomes with the robotic approach. A systematic review and meta-analysis comparing outcomes of robotic and laparoscopic hiatal hernia repairs (HHR) and Heller myotomy (HM) repairs is needed. STUDY DESIGN: PubMed, EMBASE, and SCOPUS databases were searched for studies published between January 2010 and November 2022. The risk of bias was assessed using the Cochrane Risk of Bias in Non-Randomized Studies of Interventions tool. Assessed outcomes included intraand postoperative outcomes. We pooled the dichotomous data using the Mantel-Haenszel random-effects model to report odds ratio (OR) and 95% CIs and continuous data to report mean difference and 95% CIs. RESULTS: Twenty-two comparative studies enrolling 196,339 patients were included. Thirteen (13,426 robotic and 168,335 laparoscopic patients) studies assessed HHR outcomes, whereas 9 (2,384 robotic and 12,225 laparoscopic patients) assessed HM outcomes. Robotic HHR had a nonsignificantly shorter length of hospital stay (LOS) (mean difference -0.41, 95% CI -0.87 to -0.05), fewer conversions to open (OR 0.22, 95% CI 0.03 to 1.49), and lower morbidity rates (OR 0.76, 95% CI 0.47 to 1.23). Robotic HM led to significantly fewer esophageal perforations (OR 0.36, 95% CI 0.15 to 0.83), reinterventions (OR 0.18, 95% CI 0.07 to 0.47) a nonsignificantly shorter LOS (mean difference -0.31, 95% CI -0.62 to 0.00). Both robotic HM and HHR had significantly longer operative times. CONCLUSIONS: Laparoscopic and robotic HHR and HM repairs have similar safety profiles and perioperative outcomes. Randomized controlled trials are warranted to compare the 2 methods, given the low-to-moderate quality of included studies. [ABSTRACT FROM AUTHOR]

BACKGROUND: Evaluating outcomes for acute intraoperative conversion to open surgery during endovascular aneurysm repair (EVAR) for abdominal aortic aneurysm (AAA) was difficult due to low incidence. This study aimed to compare 30-day outcomes between patients with acute intraoperative conversion during EVAR and planned open surgery, and to identify risk factors associated with acute conversion. STUDY DESIGN: Patients who underwent EVAR or planned open AAA repair were identified in American College of Surgeons NSQIP-targeted databases from 2012 to 2021. Patients with acute intraoperative conversion during EVAR were selected. A 1:3 propensity-score matching was used to match demographics, baseline characteristics, surgical indications, aneurysm size and extent, and emergency cases between the conversion open and planned open groups. Thirty-day postoperative outcomes were assessed. RESULTS: Of 20,566 EVAR cases, 177 (0.86%) had acute intraoperative conversion to open surgery. The conversion open group was matched to 504 of 5,249 planned open patients. Conversion open and planned open groups had comparable 30-day mortality (23.43% vs 17.46%, p = 0.09) and organ system complications, including major adverse cardiovascular event (14.86% vs 10.71%, p = 0.17), pulmonary complications (17.71% vs 24.01%, p = 0.09), and renal complications (8.57% vs 11.11%, p = 0.39). The conversion open group had lower bleeding requiring transfusion (48.57% vs 75.60%, p < 0.01), shorter operation time (p < 0.01), and shorter length of stay (p < 0.01). Other postoperative outcomes did not differ. Risk factors associated with acute intraoperative conversion included ruptured aneurysm with or without hypotension. Protective factors included hypertension and aortic distal aneurysm extent. CONCLUSIONS: Although this study does not endorse a universal "EVAR first" strategy for all patients with AAA, EVAR can be attempted first in eligible patients with AAA. Even when EVAR is unsuccessful, intraoperative conversion to open surgery still appears to be safe compared with planned open repair. [ABSTRACT FROM AUTHOR]

BACKGROUND: Incisional hernia (IH) is a known complication after colorectal surgery. Despite advances in minimally invasive surgery, colorectal surgery still requires extraction sites for specimen retrieval, increasing the likelihood of postoperative IH development. The objective of this study is to determine the effect of specimen extraction site on the rate of IH after minimally invasive right-sided colectomy for patients with available imaging. STUDY DESIGN: This is a retrospective multi-institutional cohort study at 2 large academic medical centers in the US. Adults who underwent right-sided minimally invasive colectomy from 2012 to 2020 with abdominal imaging available at least 1 year postoperatively were included in the analysis. The primary exposure was specimen extraction via a midline specimen extraction vs Pfannenstiel specimen extraction. The main outcome was the development of IH at least 1 year postoperatively as visualized on a CT scan. RESULTS: Of the 341 patients sampled, 194 (57%) had midline specimen extraction and 147 (43%) had a Pfannenstiel specimen extraction. Midline extraction patients were older (66 ± 15 vs 58 ± 16; p < 0.001) and had a higher rate of previous abdominal operation (99, 51% vs 55, 37%, p = 0.01). The rate of IH was higher in midline extraction at 25% (48) compared with Pfannenstiel extraction (0, 0%; p < 0.001). The average length of stay was higher in the midline extraction group at 5.1 ± 2.5 compared with 3.4 ± 3.1 days in the Pfannenstiel extraction group (p < 0.001). Midline extraction was associated with IH development (odds ratio 24.6; 95% CI 1.89 to 319.44; p = 0.004). Extracorporeal anastomosis was associated with a higher IH rate (odds ratio 25.8; 95% CI 2.10 to 325.71; p = 0.002). CONCLUSIONS: Patients who undergo Pfannenstiel specimen extraction have a lower risk of IH development compared with those who undergo midline specimen extraction. [ABSTRACT FROM AUTHOR]

BACKGROUND: The National Accreditation Program for Rectal Cancer (NAPRC) defined a set of standards in 2017 centered on multidisciplinary program structure, evidence-based care processes, and internal audit to address widely variable rectal cancer practices and outcomes across US hospitals. There have been no studies to-date testing the association between NAPRC accreditation and rectal cancer outcomes. STUDY DESIGN: This was a retrospective, observational study of Medicare beneficiaries aged 65 to 99 years with rectal cancer who underwent proctectomy from 2017 to 2020. The primary exposure was NAPRC accreditation and the primary outcomes included mortality (in-hospital, 30 day, and 1 year) and 30-day complications, readmissions, and reoperations. Associations between NAPRC accreditation and each outcome were tested using multivariable logistic regression with risk-adjustment for patient and hospital characteristics. RESULTS: Among 1,985 hospitals, 65 were NAPRC-accredited (3.3%). Accredited hospitals were more likely to be nonprofit and teaching with 250 or more beds. Among 20,202 patients, 2,078 patients (10%) underwent proctectomy at an accredited hospital. Patients at accredited hospitals were more likely to have an elective procedure with a minimally invasive approach and sphincter preservation. Risk-adjusted in-hospital mortality (1.1% vs 1.3%; p = 0.002), 30-day mortality (2.1% vs 2.9%; p < 0.001), 30-day complication (18.3% vs 19.4%; p = 0.01), and 1-year mortality rates (11% vs 12.1%; p < 0.001) were significantly lower at accredited compared with nonaccredited hospitals. CONCLUSIONS: NAPRC-accredited hospitals have lower risk-adjusted morbidity and mortality for major rectal cancer surgery. Although NAPRC standards address variability in practice, without directly addressing surgical safety, our findings suggest that NAPRC-accredited hospitals may provide higher quality surgical care.

OBJECTIVE: To describe the rate and surgical outcomes of sentinel lymph node (SLN) biopsy in patients with endometrial intraepithelial neoplasia (EIN). METHODS: We conducted a cohort study that used the prospective American College of Surgeons National Surgical Quality Improvement Program database. Women with EIN on postoperative pathology who underwent minimally invasive hysterectomy from 2012 to 2020 were included. The cohort was dichotomized based on the performance of SLN biopsy. Patients' characteristics, perioperative morbidity, and mortality were compared between patients who underwent SLN biopsy and those who did not. Postoperative complications were defined using the Clavien-Dindo classification system. RESULTS: Overall, 4,447 patients were included; of those, 586 (13.2%) underwent SLN biopsy. The proportion of SLN biopsy has increased steadily from 0.6% in 2012 to 26.1% in 2020 (P,.001), with a rate of 16% increase per year. In a multivariable regression that included age, body mass index (BMI), and year of surgery, a more recent year of surgery was independently associated with an increased adjusted odds ratio of undergoing SLN biopsy (1.51, 95% CI, 1.43-1.59). The mean total operative time was longer in the SLN biopsy group (139.50650.34 minutes vs 131.64655.95 minutes, P5.001). The rate of any complication was 5.9% compared with 6.7%, the rate of major complications was 2.3% compared with 2.4%, and the rate of minor complications was 4.1% compared with 4.9% for no SLN biopsy and SLN biopsy, respectively. In a single complications analysis, the rate of venous thromboembolism was higher in the SLN biopsy group (four [0.7%] vs four [0.1%], P5.013). In a multivariable regression analysis adjusted for age, BMI, American Society of Anesthesiologists classification, uterus weight, and preoperative hematocrit, the performance of SLN biopsy was not associated with any complications, major complications, or minor complications. CONCLUSION: The performance of SLN biopsy in EIN is increasing. Sentinel lymph node biopsy for EIN is associated with an increased risk of venous thromboembolism and a negligible increased surgical time. [ABSTRACT FROM AUTHOR]

OBJECTIVE: To compare inpatient hospital costs and complication rates within the 90-day global billing period among routes of hysterectomy. METHODS: The Premier Healthcare Database was used to identify patients who underwent hysterectomy between 2000 and 2020. Current Procedural Terminology codes were used to group patients based on route of hysterectomy. Comorbidities and complications were identified using International Classification of Diseases codes. Fixed, variable, and total costs for inpatient care were compared. Fixed costs consist of costs that are set for the case, such as operating room time or surgeon costs. Variable costs include disposable and reusable items that are billed additionally. Total costs equal fixed and variable costs combined. Data were analyzed using analysis of variance, t test, and χ² test, as appropriate. Factors independently associated with increased total costs were assessed using linear mixed effects models. Multivariate logistic regression was performed to evaluate associations between the route of surgery and complication rates. RESULTS: A cohort of 400,977 patients were identified and grouped by route of hysterectomy. Vaginal hysterectomy demonstrated the lowest inpatient total cost ($6,524.00 [interquartile range $4,831.60, $8,785.70]), and robotic-assisted laparoscopic hysterectomy had the highest total cost ($9,386.80 [interquartile range $6,912.40, $12,506.90]). These differences persisted with fixed and variable costs. High-volume laparoscopic and robotic surgeons (more than 50 cases per year) had a decrease in the cost difference when compared with costs of vaginal hysterectomy. Abdominal hysterectomy had a higher rate of complications relative to vaginal hysterectomy (adjusted odds ratio [aOR] 1.52, 95% CI, 1.39-1.67), whereas laparoscopic (aOR 0.85, 95% CI, 0.80-0.89) and robotic-assisted (aOR 0.92, 95% CI, 0.84-1.00) hysterectomy had lower rates of complications compared with vaginal hysterectomy. CONCLUSION: Robotic-assisted hysterectomy is associated with higher surgical costs compared with other approaches, even when accounting for surgeon volume. Complication rates are low for minimally invasive surgery, and it is unlikely that the robotic-assisted approach provides an appreciable improvement in perioperative outcomes. [ABSTRACT FROM AUTHOR]

Background: High reliability in health care requires a balance between intentionally designed systems and individual professional accountability. One element of accountability includes a process for addressing clinicians whose practices are associated with a disproportionate share of patient complaints. This study aimed to evaluate the impact of the Patient Advocacy Reporting System (PARS), a tiered intervention model to reduce patient complaints about clinicians. Methods: A retrospective cohort study was conducted involving a southeastern U.S. orthopaedic group practice. The study assessed the implementation of the PARS program and subsequent malpractice claims from 2004 to 2020. Results: The implementation of PARS was associated with an 83% reduction in malpractice claims cost per high-risk clinician after intervention (p = 0.05; Wilcoxon rank sum test). The overall practice group experienced an 87% reduction in mean annual claims cost per clinician (p = 0.007; segmented regression). The successful adoption required essential elements such as PARS champions, peer messengers, an Office of Patient Affairs, and a clear statement of practice values and professionalism expectations at the time of onboarding. Conclusions: The PARS program was successfully adopted within a surgical specialty group as a part of ongoing risk prevention and management efforts. The period following PARS was associated with a retrospectively measured reduction in malpractice claim costs. The PARS program can be effectively implemented in a large, single-specialty orthopaedic practice setting and, although not necessarily causal, was, in our case, associated with a period of reduced malpractice claim costs. Clinical Relevance: We have learned in previous research that there are clear links between professionalism and patient outcomes (e.g., surgical complications), but agree that the focus here on medical malpractice is not directly clinical.

Study Design. Retrospective cohort. Objective. To compare rates of all-cause surgical and medical complications between zero-profile (ZP; stand-alone) implants versus any graft type with an anterior plate in patients undergoing 1-2 level anterior cervical discectomy and fusion (ACDF) for treatment of degenerative cervical myeloradiculopathy. Summary of Background Data. Degenerative cervical myeloradiculopathy is increasingly prevalent in older adults. ACDF is a common surgical procedure for decompression of neural structures and stabilization and has been shown to have excellent outcomes. Although ACDFs performed with graft and plate have been the gold standard, more recently, ZP implants were developed to decrease implant-related complications, such as severe postoperative dysphagia. However, there is a paucity of papers comparing the surgical and medical complications profile of ZP (stand-alone) implants to grafts with plating systems. Materials and Methods. Data were extracted from the Pearl- Diver Mariner Database using Current Procedural Terminology codes to classify patients into 1 level, 2 levels, and a total of 1-2 level ACDFs. Patients undergoing surgery for non-degenerative pathologies such as tumors, trauma, or infection were excluded. Results. 1:1 exact matching created 2 equal groups of 7284 patients who underwent 1-2 level ACDF with either grafting with a plate or ZP (stand-alone) implant. There were no statistically significant differences in all-cause surgical complications, pseudarthrosis rate, dysphagia, or need for revision surgery between both cohorts (risk ratio: 0.99, 95% CI: 0.80--1.21, P = 0.95). In addition, all-cause medical complications were similar between both cohorts (risk ratio: 1.07, 95% CI: 0.862--1.330, P = 0.573) or any specific surgical or medical complication included in this study. Conclusion. After 1:1 exact matching, the results of this study suggest that ZP (stand-alone) implants have similar outcomes compared with grafts with plating systems, with no observed differences in all-cause surgical or medical complications profile.

Background: Ankle fracture is a common injury and often requires operative treatment. This study investigated short-term (£4 months) and long-term (>4 months) complications after ankle fracture surgery in a 23-year period with use of data from a comprehensive, nationwide, individual-level register. Methods: Data regarding patients who underwent operative treatment for ankle fracture were collected from the Finnish Care Register for Health Care and analyzed with use of logistic and Cox regression. Results: Atotal of 83,666 ankle fractures were operatively treated between 1998 and 2020. Of these, 36% were lateral malleolar fractures, 7% were medial malleolar fractures, 52% were bimalleolar or trimalleolar fractures, and 5% were other types of fractures. Fifty-one percent of the fractures were in female patients. The overall rate of short-term complications was 7.2%. Specifically, infection occurred in 4.4% of cases; thromboembolic complications,1.6% of cases; mechanical complications, 0.4% of cases; and other complications, 0.9% of cases. An age of >75 years was associated with a higher rate of short-term complications than an age of 51 to 75 years, with an odds ratio of 1.53 in the multivariable analysis (95% confidence interval, 1.39 to 1.67; p < 0.001). Short-term complications were also more prevalent in patients with diabetes (with or without associated complications); chronic pulmonary, kidney, or liver disease; or peripheral vascular disease. Mortality during the first 4 months after the ankle fracture operation was 0.6%. The most common reason for reoperation in the long term (>4 months after the index procedure) was fixation device removal, with a cumulative incidence of 17% within the first 3 years postoperatively. The risk of implant removal increased in younger patients and patients with bimalleolar or trimalleolar fractures. The cumulative incidence of ankle arthrodesis and arthroplasty was low. Conclusions: Although postoperative complications are relatively rare, their treatment can lead to considerable morbidity. The findings of this study allow us to identify patients who are prone to complications or reoperations after undergoing operative treatment for ankle fracture. [ABSTRACT FROM AUTHOR]

BACKGROUND: Colectomies and proctectomies are commonly performed by both general surgeons (GS) and colorectal surgeons (CRS). The aim of our study was to examine the outcomes of elective colectomy, urgent colectomy, and elective proctectomy according to surgeon training. STUDY DESIGN: Data were obtained from the Vizient database for adults who underwent elective colectomy, urgent colectomy, and elective proctectomy from 2020 to 2022. Operations performed in the setting of trauma and patients within the database's highest relative expected mortality risk group were excluded. Outcomes were compared according to surgeon's specialty: GS vs CRS. The primary outcome was in-hospital mortality. The secondary outcome was in-hospital complication rate. Data were analyzed using multivariate logistic regression. RESULTS: Of 149,516 elective colectomies, 75,711 (50.6%) were performed by GS and 73,805 (49.4%) by CRS. Compared with elective colectomies performed by CRS, elective colectomies performed by GS had higher rates of complications (4.9% vs 3.9%, odds ratio [OR] 1.23, 95% CI 1.17 to 1.29, p < 0.01) and mortality (0.5% vs 0.2%, OR 2.06, 95% CI 1.72 to 2.47, p < 0.01). Of 71,718 urgent colectomies, 54,680 (76.2%) were performed by GS, whereas 17,038 (23.8%) were performed by CRS. Compared with urgent colectomies performed by CRS, urgent colectomies performed by GS were associated with higher rates of complications (12.1% vs 10.4%, OR 1.14, 95% CI 1.08 to 1.20, p < 0.01) and mortality (5.1% vs 2.3%, OR 2.08, 95% CI 1.93 to 2.23, p < 0.01). Of 43,749 elective proctectomies, 28,458 (65.0%) were performed by CRS and 15,291 (35.0%) by GS. Compared with proctectomies performed by CRS, those performed by GS were associated with higher rates of complications (5.3% vs 4.4%, OR 1.16, 95% CI 1.06 to 1.27, p < 0.01) and mortality (0.3% vs 0.2%, OR 1.49, 95% CI 1.02 to 2.20, p = 0.04). CONCLUSIONS: In this nationwide study, colectomies and proctectomies performed by CRS were associated with improved outcomes compared with GS. Hospitals without a CRS on staff should consider prioritizing recruiting CRS specialists. [ABSTRACT FROM AUTHOR]

Background Diffuse-type tenosynovial giant-cell tumor (D-TGCT), formerly known as pigmented villonodular synovitis, is a rare, locally aggressive, invasive soft tissue tumor that primarily occurs in the knee. Surgical excision is the main treatment option, but there is a high recurrence rate. Arthroscopic surgical techniques are emphasized because they are less traumatic and offer faster postoperative recovery, but detailed reports on arthroscopic techniques and outcomes of D-TGCT in large cohorts are still lacking. Questions/purposes (1) What is the recurrence rate of knee D-TGCT after multiportal arthroscopic synovectomy? (2) What are the complications, knee ROM, pain score, and patient-reported outcomes for patients, and do they differ between patients with and without recurrence? (3) What factors are associated with recurrence after arthroscopic treatment in patients with D-TGCT? Methods In this single-center, retrospective study conducted between January 2010 and April 2021, we treated 295 patients with knee D-TGCTs. We considered patients undergoing initial surgical treatment with multiportal arthroscopic synovectomy as potentially eligible. Based on that, 27% (81 of 295) of patients were excluded because of recurrence after synovectomy performed at another institution. Of the 214 patients who met the inclusion criteria, 17% (36 of 214) were lost to follow-up, leaving 83% (178 of 214) of patients in the analysis. Twenty-eight percent (50 of 178) of patients were men and 72% (128 of 178) were women, with a median (range) age of 36 years (7 to 69). The median follow-up duration was 80 months (26 to 149). All patients underwent multiportal (anterior and posterior approaches) arthroscopic synovectomy, and all surgical protocols were determined by discussion among four surgeons after preoperative MRI. A combined open posterior incision was used for patients with lesions that invaded or surrounded the blood vessels and nerves or invaded the muscle space extraarticularly. Standard postoperative adjuvant radiotherapy was recommended for all patients with D-TGCT who had extraarticular and posterior compartment invasion; for patients with only anterior compartment invasion, radiotherapy was recommended for severe cases as assessed by the surgeons and radiologists based on preoperative MRI and intraoperative descriptions. Postoperative recurrence at 5 years was calculated using a Kaplan-Meier survivorship estimator. The WOMAC score (0 to 96, with higher scores representing a worse outcome; minimum clinically important difference [MCID] 8.5), the Lysholm knee score (0 to 100, with higher scores being better knee function; MCID 25.4), the VAS for pain (0 to 10, with higher scores representing more pain; MCID 2.46), and knee ROM were used to evaluate functional outcomes. Because we did not have preoperative patientreported outcomes scores, we present data on the proportion of patients who achieved the patient-acceptable symptom state (PASS) for each of those outcome metrics, which were 14.6 of 96 points on theWOMAC, 52.5 of 100 points on the Lysholm, and 2.32 of 10 points on the VAS. Results The symptomatic or radiographically documented recurrence at 5 years was 12% (95% confidence interval [CI] 7% to 17%) using the Kaplan-Meier estimator, with a mean recurrence time of 33 ± 19 months. Of these, three were asymptomatic recurrences found during regular MRI reviews, and the remaining 19 underwent repeat surgery. There was one intraoperative complication (vascular injury) with no effect on postoperative limb function and eight patients with postoperative joint stiffness, seven of whom improved with prolonged rehabilitation and one with manipulation under anesthesia. No postradiotherapy complications were found. The proportion of patients who achieved the preestablished PASS was 99% (176 of 178) for the VAS pain score, 97% (173 of 178) for theWOMAC score, and 100% (178 of 178) for the Lysholm score. A lower percentage of patients with recurrence achieved the PASS for WOMAC score than patients without recurrence (86% [19] versus 99% [154], OR 0.08 [95% CI 0.01 to 0.52]; p = 0.01), whereas no difference was found in the percentage of VAS score (95% [21] versus 99% [155], OR 0.14 [95% CI 0.01 to 2.25]; p = 0.23) or Lysholm score (100% [22] versus 100% [156], OR 1 [95% CI 1 to 1]; p = 0.99). Moreover, patients in the recurrence group showed worse knee flexion (median 135° [100° to 135°] versus median 135° [80° to 135°]; difference of medians 0°; p = 0.03), worse WOMAC score (median 3.5 [0 to 19] versus median 1 [0 to 29]; difference of medians 2.5; p = 0.01), and higher VAS pain score (median 1 [0 to 4] versus median 0 [0 to 4]; difference of medians 1; p < 0.01) than those in the nonrecurrence group, although no differences reached the MCID. No factors were associated with D-TGCT recurrence, including the use of postoperative radiotherapy, surgical technique, and invasion extent. Conclusion This single-center, large-cohort retrospective study confirmed that multiportal arthroscopic surgery can be used to treat knee D-TGCTs with a low recurrence rate, few complications, and satisfactory postoperative outcomes. Surgeons should conduct a thorough preoperative evaluation, meticulous arthroscopic synovectomy, and regular postoperative follow-up when treating patients with D-TGCT to reduce postoperative recurrence. Because the available evidence does not appear to fully support the use of postoperative adjuvant radiotherapy in all patients with D-TGCTs and our study design is inadequate to resolve this controversial issue, future studies should look for more appropriate indications for radiotherapy, such as planning based on a more precise classification of lesion invasion. Level of Evidence Level III, therapeutic study. [ABSTRACT FROM AUTHOR]

Background Pseudotumor formation is a well-known complication in metal-on-metal (MoM) THA. Pseudotumors combined with elevated serum ion levels and complaints from patients can lead to high revision rates. Long-term (> 10 years) results obtained from randomized trials comparing large-head MoM THA and conventional metal-on-polyethylene (MoP) THA are lacking regarding revision and survival rates, pseudotumor formation, functional outcomes, and serum ion levels. Questions/purposes At 10 years of follow-up, (1)what is the difference in survival and revision rates between large-head (38 to 60 mm) MoM THA and conventional 28-mm MoP THA? (2) What is the difference in pseudotumor formation between large-headMoM THA and MoP THA? (3) Is there a difference in functional outcome between large-head MoM THA and MoP THA? (4)What is the difference in serum ion levels between large-head MoM THA and MoP THA? Methods Between January 2006 and December 2008, 104 patients were randomized to receive either cementless MoM THA (50 patients) or cementless MoP THA (54 patients). In all, 78% (81 of 104) of patients completed the 10-year postoperative follow-up: 36 patients with MoM THA (72%; six patients lost to follow-up) and 45 with MoP THA (83%; four lost to follow-up). In the MoM group, 47% (17) were men, and the patients had a mean 6 SD age of 6065 years. In the MoP group, 38% (17) were men, and the patients had a mean age of 61 6 5 years. All baseline characteristics were similar between the groups. At 10 years of follow-up, all patient records were screened for revision surgery or complications, and the primary endpoint was survivorship free from revision for any cause at the 10-year follow-up interval, which we analyzed using a Kaplan-Meier survival analysis. All patients had a CT scan to determine the pseudotumor classification, which was reviewed by an independent radiologist. Functional outcome was measured using the patient-reported Oxford Hip Score and Harris Hip Score; the latter was assessed by a blinded nurse practitioner. Finally, serum ion cobalt and chrome concentrations were measured at 10 years postoperatively. Because the a priori sample size calculation for this randomized controlled trial was based on a different endpoint, a post hoc power analysis was performed for this long-term follow-up study, with survival as the primary outcome. It showed that considering the number of included patients, this study would have sufficient power (one-sided testing, alpha 0.05, power 80%) to discern a difference of 20% in the survival rate between the MoP and MoM groups (95% versus 75%). Results With the numbers available, there was no difference in survivorship free from revision for any cause between the MoP group andMoM group at 10 years (95% [95% CI 85% to 98%] versus 92% [95% CI 82% to 98%]; p = 0.6). A higher percentage of patients in theMoMgroup had pseudotumors on CT than those in the MoP group did, but pseudotumors were observed in both groups (56% [20 of 36] in the MoM group versus 22% [10 of 45] in theMoP group, relative risk 1.8 [95% CI 1.2 to 2.6]; p = 0.002). A higher proportion of elevated cobalt and chrome levels was found in the MoM group (19% and 14%, respectively) than in the MoP group (0% for both cobalt and chrome) (cobalt: RR 1.2 [95% CI 1.1 to 1.5]; p = 0.002; chrome: RR 1.2 [95% CI 1.0 to 1.3]; p = 0.01). In 25% of the patientswith pseudotumors (5 of 20 patients), there were elevated serum cobalt levels. None of the 23 patients without pseudotumors had elevated cobalt levels (RR 1.3 [95% CI 1.0 to 1.7]; p = 0.01). There was no difference in functional outcome between study groups, nor a difference between patients with a pseudotumor and those without. Conclusion This study showed that the survival of patients with large-head MoM THA was high and comparable to that of those with MoP THA, which contrasts with the high revision rates reported by others. Although some patients with MoP THAs experienced pseudotumors, the risk of a pseudotumor was much greater in MoM hips, and serum ion levels were higher in patients who received an MoM THA. For these reasons and unknown future complications, continued surveillance of patients with MoM THAs seems important. Level of Evidence Level I, therapeutic study. [ABSTRACT FROM AUTHOR]

Halo gravity traction (HGT) is a preoperative modality for children with severe spinal deformity used to optimize spine flexibility and balance while decreasing the likelihood of neurologic injury. HGT is a dependable solution for these challenging spinal deformities. Aligning treatment guidelines and providing resources, education, and training for staff are key components for a successful HGT program. The HGT program at Children's Mercy Hospital was then developed with a systems approach with the holistic goal of multidisciplinary collaboration with physical/occupational therapy, hospital medicine, pulmonology, psychology, nutrition, child life, and complex care management. Education, research, and national collaboration to standardize this therapy should improve patient safety and support quality improvement. [ABSTRACT FROM AUTHOR]

Background: The comparative effectiveness of decompression plus lumbar facet arthroplasty versus decompression plus instrumented lumbar spinal fusion in patients with lumbar spinal stenosis and grade-I degenerative spondylolisthesis is unknown. Methods: In this randomized, controlled, Food and Drug Administration Investigational Device Exemption trial, we assigned patients who had single-level lumbar spinal stenosis and grade-I degenerative spondylolisthesis to undergo decompression plus lumbar facet arthroplasty (arthroplasty group) or decompression plus fusion (fusion group). The primary outcome was a predetermined composite clinical success score. Secondary outcomes included the Oswestry Disability Index (ODI), visual analog scale (VAS) back and leg pain, Zurich Claudication Questionnaire (ZCQ), Short Form (SF)-12, radiographic parameters, surgical variables, and complications. Results: A total of 321 adult patients were randomized in a 2:1 fashion, with 219 patients assigned to undergo facet arthroplasty and 102 patients assigned to undergo fusion. Of these, 113 patients (51.6%) in the arthroplasty group and 47 (46.1%) in the fusion group who had either reached 24 months of postoperative follow-up or were deemed early clinical failures were included in the primary outcome analysis. The arthroplasty group had a higher proportion of patients who achieved composite clinical success than did the fusion group (73.5% versus 25.5%; p < 0.001), equating to a between-group difference of 47.9% (95% confidence interval, 33.0% to 62.8%). The arthroplasty group outperformed the fusion group in most patient-reported outcome measures (including the ODI, VAS back pain, and all ZCQ component scores) at 24 months postoperatively. There were no significant differences between groups in surgical variables or complications, except that the fusion group had a higher rate of developing symptomatic adjacent segment degeneration. Conclusions: Among patients with lumbar spinal stenosis and grade-I degenerative spondylolisthesis, lumbar facet arthroplasty was associated with a higher rate of composite clinical success than fusion was at 24 months postoperatively. Level of Evidence: Therapeutic Level I. See Instructions for Authors for a complete description of levels of evidence. [ABSTRACT FROM AUTHOR]

Objective. Provide benchmarks for the rates of complications by type and timing. Study Design. Prospective multicenter database. Background. Complication rates following adult spinal deformity (ASD) surgery have been previously reported. However, the interplay between timing and complication type warrants further analysis. Methods. The data for this study were sourced from a prospective, multicenter ASD database. The date and type of complication were collected and classified into three severity groups (minor, major, and major leading to reoperation). Only complications occurring before the two-year visit were retained for analysis. Results. Of the 1260 patients eligible for two-year follow-up, 997 (79.1%) achieved two-year follow-up. The overall complication rate was 67.4% (N=672). 247 patients (24.8%) experienced at least one complication on the day of surgery (including intraoperatively), 359 (36.0%) between postoperative day 1 and six weeks postoperatively, 271 (27.2%) between six weeks and one-year postoperatively, and finally 162 (16.3%) between one year and two years postoperatively. Using Kaplan-Meier survival analysis, the rate of remaining complication-free was estimated at different time points for different severities and types of complications. Stratification by type of complication demonstrated that most of the medical complications occurred within the first 60 days. Surgical complications presented over two distinct timeframes. Operative complications, incision-related complications, and infections occurred early (within 60 d), while implant-related and radiographic complications occurred at a constant rate over the two-year follow-up period. Neurological complications had the highest occurrence within the first 60 days but continued to increase up to the two-year visit. Conclusion. Only one-third of ASD patients remained complication- free by two years, and 2 of 10 patients had a complication requiring a reoperation or revision. An estimation of the timing and type of complications associated with surgical treatment may prove useful for more meaningful patient counseling and aid in assessing the cost-effectiveness of treatment.

When an ostomy care nurse is not available, bedside nurses must assume responsibility for providing necessary care and educating patients who undergo a urinary diversion. However, staff nurses often lack the necessary knowledge and experience to provide the best care, rehabilitation, and patient education. This article details pre- and postoperative interventions for nurses who encounter patients undergoing urostomy surgery in order to help eliminate gaps in care, increase nurses' and patients' competence and confidence, and optimize patient outcomes and quality of life. It also includes a tear sheet that nurses can use to provide patients with the basic information and skills they need for effective self-care.

FCIOL fixation is associated with a minor incidence of IOP spikes and CMO, a higher rate of tilt, dislocation, and less predictable refractive outcomes than ICIOL fixation. Purpose: To evaluate which secondary intraocular lens (IOL) implantation technique was more successful in achieving the best postoperative results and refractive outcomes between retropupillary iris-claw IOL (ICIOL) and flanged intrascleral IOL (FIIOL) fixation with the Yamane technique. Setting: Eye Clinic of the University of Trieste, Trieste, Italy. Design: Retrospective observational study. Methods: 116 eyes of 110 patients who underwent ICIOL or FIIOL were analyzed. Patients with follow-up shorter than 6 months or with incomplete clinical data were excluded. Collected data included demographics, ocular comorbidity, indication of surgery, intraocular pressure, early (≤1 month) and late (>1 month) postoperative complications, corrected distance visual acuity (CDVA), and manifest refraction at the last follow-up visit. Results: 50% (n = 58) of eyes underwent FIIOL and 50% (n = 58) ICIOL implantation for aphakia (n = 44, 38%) and IOL dislocation (n = 72, 62%). No statistically significant differences in demographics, comorbidity, follow-up duration, postoperative complications, and surgical indications were found. The refractive prediction error (RPE) was 0.69 ± 0.94 diopter (D) in the FIIOL group and 0.21 ± 0.75 D in the ICIOL group (P =.03), indicating residual hyperopia after both techniques. RPE, mean absolute error, and median absolute error were higher in the FIIOL group (P =.003). ICIOL implantation was more successful in obtaining a RPE between −0.50 D and +0.50 D (52% of ICIOL, n = 30, and 31% of FIIOL, n = 18). Conclusions: Both techniques were effective in increasing preoperative CDVA with no statistical difference between them. Although complication rates did not significantly differ, the FIIOL group exhibited less predictable refractive outcomes. Adjusting the dioptric power of the 3-piece IOL, as performed in ciliary sulcus implantation, to prevent myopic shift, is not recommended. [ABSTRACT FROM AUTHOR]

Study Design: Retrospective cohort study. Objective: To compare surgical and medical complications profile between neurosurgeons and orthopedic surgeons after transforaminal lumbar interbody fusion (TLIF) procedures. Background: Studies comparing the impact of spine surgeon specialty (neurosurgery vs. orthopedic spine) on TLIF outcomes have been inconclusive and failed to control for operative learning curves and surgical maturity. Orthopedic spine surgeons perform fewer spine procedures in residency, although these differences may be attenuated by mandatory fellowship before starting practice. Any observed differences are likely attenuated with increasing surgeon experience. Materials and Methods: Using an all-payer claims database, PearlDiver Mariner, 120 million patient records were analyzed between 2010 and 2022, to identify individuals with lumbar stenosis or spondylolisthesis who underwent index one- to three-level TLIF procedures. International Classification of Diseases--Ninth Edition (ICD- 9), International Classification of Diseases--10th Edition (ICD-10) and Current Procedural Terminology (CPT) codes were used to query the database. Only Neurosurgeons and Orthopedic spine surgeons who had performed at least 250 procedures were included in the study. Patients undergoing surgery for tumor, trauma, or infection were excluded. 1:1 exact matching was performed using demographic factors, medical comorbidities, and surgical factors which were significantly associatedwith all-cause surgical ormedical complications in a linear regression model. Results: 1:1 exact matching created two equal groups of 18,195 patients without baseline differences who underwent TLIF procedures by neurosurgeons or orthopedic surgeons. There was no difference in all-cause surgical complications between neurosurgeons and orthopedic spine surgeons (relative risk=1.008, 95% CI: 0.850--1.195, P=0.965). All-cause medical complication rate was higher in the neurosurgery cohort (relative risk =1.144, 95% CI: 1.042--1.258, P= 0.005). Conclusion: The results of this study suggest that after accounting for surgical maturity, neurosurgeons and orthopedic spine surgeons have similar surgical outcomes. However, neurosurgeons have higher all-cause medical complication rates compared with orthopedic spine surgeons. Further research is warranted to validate this relationship in other spine procedures and for other outcomes. [ABSTRACT FROM AUTHOR]

Also noted are the challenges of unclear roles and practice scope among stakeholders.

BACKGROUND: Ventral hernias result in fibrosis of the lateral abdominal wall muscles, increasing tension on fascial closure. Little is known about the effect of abdominal wall tension on outcomes after abdominal wall reconstruction. We aimed to identify an association between abdominal wall tension and early postoperative outcomes in patients who underwent posterior component separation (PCS) with transversus abdominis release (TAR). STUDY DESIGN: Using a proprietary, sterilizable tensiometer, the tension needed to bring the anterior fascial elements to the midline of the abdominal wall during PCS with TAR was recorded. Tensiometer measurements, in pounds (lb), were calibrated by accounting for the acceleration of Earth's gravity. Baseline fascial tension, change in fascial tension, and fascial tension at closure were evaluated with respect to 30-day outcomes, including wound morbidity, hospital readmission, reoperation, ileus, bleeding, and pulmonary complications. RESULTS: A total of 100 patients underwent bilateral abdominal wall tensiometry, for a total of 200 measurements (left and right side for each patient). Mean baseline anterior fascial tension was 6.78 lb (SD 4.55) on each side. At abdominal closure, the mean anterior fascial tension was 3.12 (SD 3.21) lb on each side. Baseline fascial tension and fascial tension after PCS with TAR at abdominal closure were not associated with surgical site infection, surgical site occurrence, readmission, ileus, and bleeding requiring transfusion. The event rates for all other complications were too infrequent for statistical analysis. CONCLUSIONS: Baseline and residual fascial tension of the anterior abdominal wall do not correlate with early postoperative morbidity in patients undergoing PCS with TAR. Further work is needed to determine if abdominal wall tension in this context is associated with long-term outcomes, such as hernia recurrence. [ABSTRACT FROM AUTHOR]

BACKGROUND: As the COVID-19 pandemic shifts to an endemic phase, an increasing proportion of patients with cancer and a preoperative history of COVID-19 will require surgery. This study aimed to assess the influence of preoperative COVID-19 on postoperative risk for major adverse cardiovascular and cerebrovascular events (MACEs) among those undergoing surgical cancer resection. Secondary objectives included determining optimal time-to-surgery guidelines based on COVID-19 severity and discerning the influence of vaccination status on MACE risk. STUDY DESIGN: National COVID Cohort Collaborative Data Enclave, a large multi-institutional dataset, was used to identify patients that underwent surgical cancer resection between January 2020 and February 2023. Multivariate regression analysis adjusting for demographics, comorbidities, and risk of surgery was performed to evaluate risk for 30-day postoperative MACE. RESULTS: Of 204,371 included patients, 21,313 (10.4%) patients had a history of preoperative COVID-19. History of COVID-19 was associated with an increased risk for postoperative composite MACE as well as 30-day mortality. Among patients with mild disease who did not require hospitalization, MACE risk was elevated for up to 4 weeks after infection. Postoperative MACE risk remained elevated more than 8 weeks after infection in those with moderate disease. Vaccination did not reduce risk for postoperative MACE. CONCLUSIONS: Together, these data highlight that assessment of the severity of preoperative COVID-19 infection should be a routine component of both preoperative patient screening as well as surgical risk stratification. In addition, strategies beyond vaccination that increase patients' cardiovascular fitness and prevent COVID-19 infection are needed. [ABSTRACT FROM AUTHOR]

BACKGROUND: Hospital-acquired urinary tract infections (UTIs) have a detrimental effect on patients, families, and hospital resources. The Sydney Children's Hospital Network (SCHN) participates in the NSQIP-Pediatric (NSQIP-P) to monitor postoperative complications. NSQIP-P data revealed that the median UTI rate at SCHN was 1.75% in 2019, 3.5 times higher than the NSQIP-P target rate of 0.5%. Over three quarters of the NSQIP-P identified patients with UTI also had a urinary catheterization performed intraoperatively. A quality improvement project was conducted between mid-2018 and 2021 to minimize catheter-associated UTIs (CAUTIs) at SCHN. STUDY DESIGN: NSQIP-P samples include pediatric (younger than 18 years) surgical patients from an 8-day cycle operative log. NSQIP-P data are statistically analyzed by the American College of Surgeons and provide biannual internationally benchmarked reports. The project used clinical redesign methodology with a 6-phase process for quality improvement projects. RESULTS: The objectives of the project were to reduce urinary catheter duration of use, educate parents or carers, and improve catheter care and insertion technique by health staff. The duration of a urinary catheter in situ reduced from a median of 4.5 to 3 days from 2017 to 2021. The median NSQIP-P UTI rate at SCHN was reduced by 47.4% from 1.75% in 2019 to 0.9% in 2022. CONCLUSIONS: A multifactorial approach in quality improvement has been shown to be an effective strategy to reduce UTI rates at SCHN, and patient outcomes were improved within a 3-year timeframe. Although this project has reduced UTI rates at SCHN, there remain opportunities for further improvement. [ABSTRACT FROM AUTHOR]

BACKGROUND: With increasing implementation of Enhanced Recovery After Surgery protocols and rising demand for inpatient hospital beds accentuated by COVID-19, there has been interest in same-day discharge (SDD) for bariatric surgery. The aim of this study was to determine the national trends, safety profile, and risk factors for complications of SDD for minimally invasive bariatric surgery. STUDY DESIGN: We analyzed the MBSAQIP database from 2016 to 2021 to characterize trends in SDD for minimally invasive bariatric operation. Multivariate logistic regression was performed on preoperative patient characteristics predictive of increased complications associated with SDD. A comparative analysis of postoperative outcomes within 30 days was performed for SDD and admission after 1:1 nearest neighbor propensity score matching for patient demographics and preoperative comorbidities. RESULTS: SDD increased from 2.4% in 2016 to 7.4% in 2021. Major preoperative factors associated with increased complications for SDD included Black race, history of MI, renal insufficiency, deep vein thrombosis, and smoking. SDD for Roux-en-Y gastric bypass had 72% increased risk of postoperative complications compared with sleeve gastrectomy. The overall major complications were lower in SDD cohort vs admission cohort (odds ratio [OR] 0.62, p < 0.01). However, there was a significant increase in deaths within 30 days (OR 2.11, p = 0.01), cardiac arrest (OR 2.73; p < 0.01), and dehydration requiring treatment (OR 1.33; p < 0.01) in SDD cohort compared with admission cohort. CONCLUSIONS: Nationally, there has been a rise in SDD for bariatric operation from 2016 to 2021. Matched analysis demonstrates that SDD is associated with a significantly higher mortality rate. Additionally, the risk of complications with SDD is higher for RYGB compared with sleeve gastrectomy. Therefore, further studies are required to appropriately select patients for whom bariatric surgery can be safely performed as an outpatient. [ABSTRACT FROM AUTHOR]

BACKGROUND: The aim of this study is to evaluate the impact of preoperative weight loss on surgical outcomes and operating room (OR) times after primary bariatric procedures, including laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (RYGB). STUDY DESIGN: A retrospective cohort study uses the 2021 MBSAQIP dataset. Preoperative total weight loss (TWL)% was calculated. Patients were then divided in to 4 groups: those with no weight loss, lost <0 to <5%, lost =5% to <10%, or lost =10% TWL preoperatively. These groups were then stratified into those with BMI less than 50 kg/m2 and those with BMI 50 kg/m2 or more and 30-day outcomes and OR times were compared. RESULTS: Analysis included 171,010 patients. For BMI less than 50 kg/m2, preoperative weight loss led to no consistent improvement in surgical outcomes. Although >0% to <5% TWL led to a decrease in intra- and postoperative occurrences after RYGB and a decrease in reoperation rates after LSG, these observations were not seen in those with higher degree of weight loss. In patients with BMI 50 kg/m2 or more, preoperative weight loss showed a consistent improvement in reintervention rates after LSG, and readmission rates after RYGB. There was no improvement in other outcomes, however, irrespective of degree of preoperative weight loss. CONCLUSIONS: In patients undergoing primary bariatric surgery, preoperative weight loss does not lead to a consistent improvement in outcomes or OR times. In those with BMI 50 kg/m2 or more, there may be improvement in select outcomes that is procedure-specific. Overall, these data do not support a uniform policy of preoperative weight loss, although selective use in some high-risk patients may be appropriate. [ABSTRACT FROM AUTHOR]

This article discusses the relationship between spinopelvic alignment and outcomes in patients undergoing periacetabular osteotomy (PAO) for symptomatic acetabular dysplasia. The study found that certain preoperative factors, such as decreased lumbar spine mobility and standing pelvic tilt, were associated with changes in spinopelvic parameters after PAO. However, the magnitude of these changes was small, suggesting that PAO does not significantly alter preoperative sagittal alignment in most patients. The article highlights the need for further research to understand the impact of spinopelvic parameters on PAO outcomes and to determine appropriate preoperative functional acetabular orientation.

Purpose: Neuromuscular deficits and atrophy after anterior cruciate ligament reconstruction (ACLR) may be accompanied by changes in muscle composition and poor quadriceps muscle quality (QMQ). Quadriceps atrophy occurs after ACLR but improves within the first three postoperative months, yet this hypertrophy could be attributable to increases in noncontractile tissue (i.e., poor QMQ). The purposes of this study were to evaluate changes in QMQ after ACLR and to determine if changes in QMQ and cross-sectional area (CSA) occur in parallel or independently. Methods: A longitudinal prospective cohort design was implemented to evaluate QMQ and CSA in 20 individuals with ACLR and 12 healthy controls. Participants completed three testing sessions (baseline/presurgery, 1 month, and 3 months) during which ultrasound images were obtained from the vastus lateralis (VL) and rectus femoris (RF). QMQ was calculated as the echo intensity (EI) of each image, with high EI representing poorer QMQ. Anatomical CSA was also obtained from each image. Results: RF and VL EI were greater at 1 and 3 months in the ACLR limb compared with baseline and the contralateral limb and did not change between 1 and 3 months. VL and RF CSA in the ACLR limb were smaller at 1 and 3 months compared with the contralateral limb and controls (VL only) but increased from 1 to 3 months. Changes in QMQ and CSA were not correlated. Conclusions: QMQ declines within the first month after ACLR and does not improve by 3 months although hypertrophy occurs, suggesting that these morphological characteristics change independently after ACLR. Poorer QMQ represents greater concentration of noncontractile tissues within the muscle and potentially contributes to chronic quadriceps dysfunction observed after ACLR. [ABSTRACT FROM AUTHOR]

Objective: The aim of the study is to comprehensively assess the recovery effects of high-frequency repetitive transcranial magnetic stimulation in patients with poststroke cognitive impairment. Methods: Six English and four Chinese databases were searched for relevant studies published up to January 2022. Randomized controlled trials of patients with poststroke cognitive impairment treated with high-frequency repetitive transcranial magnetic stimulation were included. Included studies were assessed for the risk of bias through the Cochrane Intervention Systematic Review Manual 5.1.0. The meta-analysis was performed using RevMan 5.4 software. The PRISMA 2020 guidelines were followed. Results: Sixty-one randomized controlled trials (4012 patients) were included. Montreal Cognitive Assessment Score, Mini-Mental State Examination score, event-related potential P300 (P300) amplitude, Loewenstein Occupational Therapy Cognitive Assessment score, and total effective rate of cognitive function were higher in the high-frequency repetitive transcranial magnetic stimulation group than in the control group at the end of the treatment period, and scores of Alzheimer Disease Assessment Scale-Cognitive Subscale and P300 latency were lower in the high-frequency repetitive transcranial magnetic stimulation group than in the control group. Fifty studies had selected the dorsolateral prefrontal cortex as the stimulation site for high-frequency repetitive transcranial magnetic stimulation. Conclusions: Compared with nonrepetitive transcranial magnetic stimulation or sham repetitive transcranial magnetic stimulation, high-frequency repetitive transcranial magnetic stimulation not only improves the overall cognitive function of poststroke cognitive impairment patients but also has better rehabilitation results.

Purpose: To determine the visual outcome and postoperative complications of cataract surgery in patients with ocular surface disorders (OSDs). Setting: Tertiary eyecare center in North India. Design: Retrospective observational study. Methods: Patients with various OSDs with stabilized ocular surfaces who underwent cataract surgery during this period and had a minimum postoperative follow-up of 6 weeks were included. The primary outcome measures were postoperative corrected distance visual acuity (CDVA) at 6 weeks, best CDVA achieved, and post-operative complications. Results: The study included 20 men and 24 women. A total of 55 eyes were evaluated: Stevens-Johnson syndrome (SJS) 35 eyes, ocular cicatricial pemphigoid (OCP) 4 eyes, 8 eyes with dry eye disease (DED), 6 eyes with chemical injury and 2 eyes with vernal keratoconjunctivitis (VKC). The mean duration of OSD was 33.9 ± 52.17 months. The median preoperative CDVA was 2.0 (interquartile range [IQR], 1.45 to 2.0). The median CDVA ever achieved was 0.50 (IQR, 0.18 to 1.45) at 2 months and the median CDVA at 6 weeks was 0.6 (IQR, 0.3 to 1.5). Maximum improvement in CDVA was noted in patients with DED and SJS and the least in OCP. Phacoemulsification was performed in 47.27% eyes with intraoperative complications noted in 9% eyes. Postoperative surface complications occurred in 12 (21.82%) eyes. Other postoperative complications occurred in 9 (16%) eyes. Conclusions: Cataract surgery outcome can be visually rewarding in patients with OSDs provided ocular surface integrity is adequately maintained preoperatively and postoperatively.

Study Design: A retrospective cohort review. Objective: To develop a scoring system for predicting increased risk of postoperative complications in adult spinal deformity (ASD) surgery based on baseline nutritional and metabolic factors. Background: Endocrine and metabolic conditions have been shown to adversely influence patient outcomes and may increase the likelihood of postoperative complications. The impact of these conditions has not been effectively evaluated in patients undergoing ASD surgery. Materials and Methods: ASD patients 18 years or above with baseline and two-year data were included. An internally crossvalidated weighted equation using preoperative laboratory and comorbidity data correlating to increased perioperative complications was developed via Poisson regression. Body mass index (BMI) categorization (normal, over/underweight, and obese) and diabetes classification (normal, prediabetic, and diabetic) were used per the Centers for Disease Control and Prevention and the American Diabetes Associates parameters. A novel ASD-specific nutritional and metabolic burden score (ASD-NMBS) was calculated via Beta-Sullivan adjustment, and Conditional Inference Tree determined the score threshold for experiencing ≥ 1 complication. Cohorts were stratified into low-risk and high-risk groups for comparison. Logistic regression assessed correlations between increasing burden score and complications. Results: Two hundred one ASD patients were included (mean age: 58.60±15.4, sex: 48% female, BMI: 29.95±14.31, Charlson Comorbidity Index: 3.75±2.40). Significant factors were determined to be age (+1/yr), hypertension (+18), peripheral vascular disease (+37), smoking status (+21), anemia (+1), VitD hydroxyl (+1/ ng/mL), BMI (+13/cat), and diabetes (+4/cat) (model: P<0.001, area under the curve: 92.9%). Conditional Inference Tree determined scores above 175 correlated with ≥1 post-op complication (P<0.001). Furthermore, HIGH patients reported higher rates of postoperative cardiac complications (P=0.045) and were more likely to require reoperation (P=0.024) compared with low patients. Conclusions: The development of a validated novel nutritional and metabolic burden score (ASD-NMBS) demonstrated that patients with higher scores are at greater risk of increased postoperative complications and course. As such, surgeons should consider the reduction of nutritional and metabolic burden preoperatively to enhance outcomes and reduce complications in ASD patients. [ABSTRACT FROM AUTHOR]

Study Design: Retrospective cohort. Objective: To compare the rates of all-cause surgical complications of synthetic interbody devices versus allograft or autograft in patients undergoing 1-2 levels anterior cervical discectomy and fusion (ACDF) procedures. Summary of Background Data: Cervical degenerative disorders affect up to 60% of older adults in the United States. Both traditional allograft or autograft and synthetic interbody devices (polyetheretherketone or titanium) are used for decompression and arthrodesis, with increasing utilization of the latter. However, the differences in their postsurgical complication profiles are not wellcharacterized. Patients and Methods: Patients who underwent 1-2 level ACDFs for cervical radiculopathy or myelopathy between 2010 and 2022 were identified using the PearlDiver Mariner all-claims insurance database. Patients undergoing surgery for nondegenerative pathologies, such as tumors, trauma, or infection, were excluded. 1:1 exact matching was performed based on factors that were significant predictors of all-cause surgical complications in a linear regression model. The primary outcome measure was the development of all-cause surgical complications after 1-2 level ACDFs. The secondary outcome was all-cause medical complications. Results: 1:1 exact matching resulted in two equal groups of 11,430 patients who received treatment with synthetic interbody devices or allograft/autograft. No statistically significant difference in all-cause surgical complications was found between the synthetic cohort and the allograft or autograft cohort after 1-2 level ACDFs (Relative Risk: 0.86, 95% confidence interval: 0.730–1.014, P = 0.079). No significant differences were observed regarding any specific surgical complications except for pseudoarthrosis (Relative Risk: 0.73, 95% confidence interval: 0.554–0.974, P = 0.037), which was higher in the allograft/autograft cohort. Conclusion: After 1:1 exact matching to control for confounding variables, the findings of this study suggest that all-cause surgical complications are similar in patients undergoing ACDFs with synthetic interbody devices or allograft/autographs. However, the rate of pseudarthrosis appears to be higher in patients with allograft/autographs. Future prospective studies are needed to corroborate these findings. [ABSTRACT FROM AUTHOR]

BACKGROUND: Acquired melanocytic nevi are common benign skin lesions that require removal under certain circumstances. Shave removal is a straightforward treatment modality with a risk of recurrence. OBJECTIVE: To evaluate the outcome of dermoscopy-guided shave removal of acquired melanocytic nevi in the face of dark-skinned individuals who are more liable to postsurgical complications. METHODS: The study was conducted on 64 patients with acquired facial melanocytic nevi. Serial shave removal using a razor blade guided by dermoscopic examination was done until nevus-free tissue was seen, followed by electrocauterization of the base. Cosmetic outcome, patients' satisfaction, and recurrence rate were evaluated during follow-up. RESULTS: Excellent cosmetic outcome was achieved in 54.69% of patients, while 39.06% had an acceptable outcome, and 6.25% of patients had poor cosmetic outcome. Meanwhile, the recurrence rate was noticed in 5 cases only (7.8%). CONCLUSION: Dermoscopic-guided shave removal provides an easy procedure of treating common melanocytic nevi with an acceptable cosmetic result and a lower rate of recurrence even in patients with darker skin phenotypes.

BACKGROUND: The notion that gas-bloat syndrome (GBS) after magnetic sphincter augmentation (MSA) is less detrimental has not been substantiated by data. This study aimed to identify the incidence, natural history, risk factors, and impact on outcomes of GBS after MSA. STUDY DESIGN: Records of patients who underwent MSA at our institution were reviewed. GBS was defined as a score of 4 or more on the gas bloat-specific item within the GERD health-related quality-of-life (GERD-HRQL) questionnaire. Preoperative clinical and objective testing data were compared between those with and without GBS at 1 year using univariate followed by multivariable analysis. GBS evolution over time and its impact on outcomes were assessed in those with 1- and 2-year follow-up. RESULTS: A total of 489 patients underwent MSA. At a mean (SD) follow-up of 12.8 (2.1) months, patient satisfaction was 88.8%, 91.2% discontinued antisecretory medications, and 74.2% achieved DeMeester score normalization. At 1 year, 13.3% of patients developed GBS, and had worse GERD-HRQL scores and antisecretory medication use and satisfaction (p < 0.0001). DeMeester score normalization was comparable (p = 0.856). Independent predictors of GBS were bloating (odds ratio [OR] 1.8, p = 0.043), GERD-HRQL score greater than 30 (OR 3, p = 0.0010), and MSA size 14 or less beads (OR 2.5, p = 0.004). In a subgroup of 239 patients with 2-year follow-up, 70.4% of patients with GBS at 1 year had resolution by 2 years. The GERD-HRQL total score improved when GBS resolved from 11 (7 to 19) to 7 (4 to 10), p = 0.016. Patients with persistent GBS at 2 years had worse 2-year GERD-HRQL total scores (20 [5 to 31] vs 5 [3 to 12], p = 0.019). CONCLUSIONS: GBS affects 13.3% of patients at 1 year after MSA and substantially diminishes outcomes. However, GBS resolves spontaneously with quality-of-life improvement. Patients with preoperative bloating, high GERD-HRQL scores, or small MSA devices are at greatest risk of this complication. [ABSTRACT FROM AUTHOR]

BACKGROUND: Despite high satisfaction rates, reduction mammaplasty can have complications such as hematoma. Factors such as age, tobacco use, and comorbidities are known contributors, whereas the influence of race, BMI, certain medications, and blood pressure (BP) remain contentious. This study investigates hematoma risk factors in young women undergoing reduction mammaplasty. STUDY DESIGN: A retrospective review was conducted including all female patients who underwent bilateral reduction mammaplasty at a single institution between 2012 and 2022. Data on demographics, BMI, medical comorbidities, surgical techniques, medications, and perioperative BP were collected. Differences between patients who developed a hematoma and those who did not were assessed using chi-square, Fisher's exact, and t-tests. The relationship between perioperative BP and hematoma formation was assessed using logistic regression. RESULTS: Of 1,754 consecutive patients, 3% developed postoperative hematoma of any kind, with 1.8% returning to the operating room. Age (odds ratio [OR] 1.14, p = 0.01) and ketorolac use (OR 3.93, p = 0.01) were associated with hematoma development. Controlling for baseline BP, each 10 mmHg incremental increase in peak intraoperative BP (systolic BP [SBP]: OR 1.24, p = 0.03; mean arterial pressure: OR 1.24, p = 0.01) and postoperative BP (SBP: OR 1.41, p = 0.01; mean arterial pressure: OR 1.49, p = 0.01) escalated the odds of hematoma. Postoperative SBP variability also incrementally increased hematoma odds (OR 1.48, p < 0.01). Other factors, including race and surgical technique, were not significantly influential. CONCLUSIONS: Age, ketorolac use, and intra- and postoperative BP peaks and variability are risk factors for hematoma in reduction mammaplasty. This emphasizes the importance of perioperative BP management and optimizing pain management protocols. [ABSTRACT FROM AUTHOR]

Background Obesity-based cutoffs in TKA are premised on higher rates of postoperative complications. However, operative time may be associated with postoperative complications, leading to an unnecessary restriction of TKA in patients with obesity. If operative time is associated with these obesity-related outcomes, it should be accounted for in order to ensure all measurable factors associated with negative outcomes are examined for patients with obesity after TKA. Questions/purposes We asked: (1) Is operative time, controlling for BMI class, associated with readmission, reoperation, and postoperative major and minor complications? (2) Is operative time associated with a difference in the direction or strength of obesity-related adverse outcomes? Methods In this comparative study, we extracted all records on elective, unilateral TKA between January 2014 and December 2020 in the American College of Surgeons National Surgical Quality Improvement Program database, resulting in an initial sample of 394,381 TKAs. Patients with emergency procedures (0.1% [270]) and simultaneous bilateral TKAs (2% [8736]), missing or null data (1% [4834]), and those with operative times less than 25 minutes (0.1% [548]) were excluded, leaving 96% (379,993) of our original sample size. The National Surgical Quality Improvement Program database was selected because of its inclusion of operative time, which is not found in any other national database. BMI was subdivided into underweight (BMI < 18.5 kg/m², < 1% [719]), normal weight (BMI 18.5 to 24.9 kg/m², 9% [34,513]), overweight (BMI 25.0 to 29.9 kg/m², 27% [101,538]), Class I obesity (BMI 30.0 to 34.9 kg/m², 29% [111,712]), Class II obesity (BMI 35.0 to 39.9 kg/m², 20% [76,605]), and Class III obesity (BMI ≥ 40.0 kg/m², 14% [54,906]). The mean operative time was 91 ± 36 minutes, 61% of patients were women (233,062 of 379,993), and the mean age was 67 ± 9 years. Patients with obesity tended to be younger and more likely to have preoperative comorbidities and longer operative times than patients with normal weight. Multivariable logistic regression models examined the main effects of operative time with respect to 30-day readmission, reoperation, and major and minor medical complications, while adjusting for BMI class and other covariates including age, sex, race, smoking status, and number of preoperative comorbidities. We then evaluated the potential interaction effect of BMI class and operative time. This interaction term helps determine whether the association of BMI with postoperative outcomes changes based on the duration of the surgery, and vice versa. If the interaction term is statistically significant, it implies the association of BMI with adverse postoperative outcomes is inconsistent across all patients. Instead, it varies with the operative time. Adjusted odds ratios and 95% confidence intervals were calculated, and interaction effects were plotted. Results After controlling for obesity, longer procedure duration was independently associated with higher odds of all outcomes (30-minute estimates; adjusted ORs are per minute), including readmission (9% per half-hour of surgical duration; adjusted OR 1.003 [95% CI 1.003 to 1.004]; p < 0.001), reoperation (15% per half-hour of surgical duration; adjusted OR 1.005 [95% CI 1.004 to 1.005]; p < 0.001), postoperative major complications (9% per half-hour of surgical duration; adjusted OR 1.003 [95% CI 1.003 to 1.004]; p < 0.001), and postoperative minor complications (18% per half-hour of surgical duration; adjusted OR 1.006 [95% CI 1.006 to 1.007]; p < 0.001). The interaction effect indicates that patients with obesity had lower odds of reoperation than patients with normal weight when operative times were shorter, but higher odds of reoperation with a longer operative duration. Conclusion We found that operative time, a proxy for surgical complexity, had a moderate, differential association with obesity over a 30-minute period. Perioperative modification of surgical complexity such as surgical techniques, training, and team dynamics may make safe TKA possible for certain patients who might have otherwise been denied surgery. Decisions to refuse TKA to patients with obesity should be based on a holistic assessment of a patient's operative complexity, rather than strictly assessing a patient's weight or their ability to lose weight. Future studies should assess patient-specific characteristics that are associated with operative time, which can further push the development of techniques and strategies that reduce surgical complexity and improve TKA outcomes.

Mental health and housing status have the potential to impact total joint arthroplasty (TJA) outcomes and are common TJA eligibility criteria that prevent patients from receiving surgery. Our aim was to formulate recommendations for how nurse navigators can assist patients with managing mental health and housing concerns. Through discussions with nurse navigators and a literature search across two databases, we gathered information regarding the optimization of mental health and housing status among TJA patients. We observed a lack of standardized protocols for addressing these concerns and literature supporting an increased focus on mental health and housing status, indicating the potential for greater nurse navigator involvement in developing and implementing protocols. We recommend nurse navigators use screening tools to identify mental health and housing concerns and offer the suggested resources to support patients in an effort to improve postoperative outcomes and decrease surgical risks.

Despite significant advancements in surgical instruments and operation skills, short- and long-term outcomes following anterior cruciate ligament reconstruction (ACLR) remain unsatisfactory, as many patients fail to return to their pre-injury level of sports. Inadequate ACL rehabilitation is the primary cause of poor outcomes. Nurses have become a crucial element in the rehabilitation process. Although there is no consensus regarding the optimal post-operative rehabilitation protocols, restoring muscle strength and neuromuscular control are consistently the primary goals. This literature review presents nurse-assisted rehabilitation protocols aiming at improving muscle strength and neuromuscular control. The review discusses postoperative rehabilitation, including home-based and supervised rehabilitation, open and closed kinetic chain exercises, eccentric and concentric training, blood flow restriction training, and plyometric training. Each training protocol has its benefits and drawbacks, and should be used cautiously in specific stages of rehabilitation. Neuromuscular training, such as neuromuscular electrical stimulation, neuromuscular control exercises, and vibration therapy, is considered crucial in rehabilitation. [ABSTRACT FROM AUTHOR]

BACKGROUND: Race and socioeconomic status incompletely identify patients with colorectal cancer (CRC) at the highest risk for screening, treatment, and mortality disparities. Social vulnerability index (SVI) was designed to delineate neighborhoods requiring greater support after external health stressors, summarizing socioeconomic, household, and transportation barriers by census tract. SVI is implicated in lower cancer center use and increased complications after colectomy, but its influence on long-term prognosis is unknown. Herein, we characterized relationships between SVI and CRC survival. STUDY DESIGN: Patients undergoing resection of stage I to IV CRC from January 2010 to May 2023 within an academic health system were identified. Clinicopathologic characteristics were abstracted using institutional National Cancer Database and NSQIP. Addresses from electronic health records were geocoded to SVI. Overall survival and cancer-specific survival were compared using Kaplan-Meier and Cox proportional hazards methods. RESULTS: A total of 872 patients were identified, comprising 573 (66%) patients with colon tumor and 299 (34%) with rectal tumor. Patients in the top SVI quartile (32%) were more likely to be Black (41% vs 13%, p < 0.001), carry less private insurance (39% vs 48%, p = 0.02), and experience greater comorbidity (American Society of Anesthesiologists physical status III: 86% vs 71%, p < 0.001), without significant differences by acuity, stage, or CRC therapy. In multivariable analysis, high SVI remained associated with higher all-cause (hazard ratio 1.48, 95% CI 1.12 to 1.96, p < 0.01) and cancer-specific survival mortality (hazard ratio 1.71, 95% CI 1.10 to 2.67, p = 0.02). CONCLUSIONS: High SVI was independently associated with poorer prognosis after CRC resection beyond the perioperative period. Acknowledging needs for multi-institutional evaluation and elaborating causal mechanisms, neighborhood-level vulnerability may inform targeted outreach in CRC care. [ABSTRACT FROM AUTHOR]
