Introduction Surgical volume at Military Treatment Facilities (MTFs) has been gradually decreasing for roughly the past 2 decades. The Knowledge, Skills, and Abilities (KSA) Clinical Readiness Program linked surgical volume and readiness using a tool known as the KSA metric. However, the extent to which military medical missions contribute to the readiness of critical wartime specialties has not been evaluated using this metric. Methods In this study, a retrospective analysis was conducted using the surgical case logs from the US Naval Ship (USNS) Comfort missions in 2018 and 2019. The comprehensive case log data were categorized by year, surgeon, procedure, and location. The analysis focused on providing detailed descriptive statistics, including percentages pertaining to the types of procedures performed during these missions. The 2018 mission was 11 weeks in duration, and supported activities in Ecuador, Peru, Colombia, and Honduras. The USNS Comfort mission in 2019 lasted 6 months (June-November 2019), and visited 12 countries in Central America, South America, and the Caribbean. Results The 2019 mission case log, spanning 6 months, was evaluated using the KSA score in order to assess readiness and compare against 6 months of MTF KSA values within the same calendar year. In 2019, the orthopedic surgeon aboard the USNS Comfort had a total KSA score of 44,006, but the 6-month USNS Comfort mission only contributed 5,364 points (12% of the annual score). The general surgery practice aboard the USNS Comfort produced lower KSA scores compared to each surgeon's respective MTF practice (Table III). Analyzing the cases logged by general surgeons also highlights minimal surgical diversity during these missions, with more than 90% of cases being hernia repairs or laparoscopic cholecystectomies (Table I). In addition, 35% of total procedures performed in 2018 and 2019 were performed laparoscopically. Conclusions The analysis of operative data from the 2019 USNS Comfort mission, in comparison with the surgeons' work at their respective MTFs, reveals limited benefit in the ability of hospital-ship missions to bolster surgical readiness as measured by the KSA score. However, this is not a reflection on the value of Global Health Engagement (GHE) itself but a review of the way in which it is leveraged to support surgical readiness. Military surgeons participate in GHE as part of a larger strategy to strengthen relationships with partner nations, improve military medical force interoperability, and bolster partner nation medical capacity and capabilities. The KSA score offers an excellent tool to compare readiness metrics across significantly different GHE missions, and facilitates the opportunity for future prospective studies to improve case volume, diversity, and ultimately readiness.

The prognosis in gastrointestinal system malignancies is directly correlated with the stage of the disease at the time of presentation. There are debates and variations in the preferred methods for staging (3,4). Despite being part of the recommendations of international associations in preoperative staging, the adequacy of CT is controversial. In our study, we aimed to investigate the effectiveness of CT in the decision of inoperability based on our case series of patients who were admitted to our clinic with a preliminary diagnosis of gastrointestinal system malignancy and deemed inoperable. At the General Surgery Clinic of - University Training and Research Hospital, demographic data of patients with intraoperatively detected inoperable gastrointestinal malignancies between 2018 and 2023, preoperative CT and endoscopy findings, surgical reports, and neoadjuvant treatment applications were retrospectively analyzed. Preoperative endoscopic and cross-sectional imaging findings were compared with intraoperative findings. The study included 91 patients. The sensitivity of preoperative endoscopy was found to be 80.2%, while the sensitivity of preoperative CT was 69.2%. When comparing organ-based intraoperative findings with the distant invasion signs findings detected in preoperative investigations, no significant difference was found. When the correlation of intraoperative inoperable and widely accepted findings with preoperative treatment was examined, no statistically significant relationship was found in the statistical analysis. In our study, the sensitivity and specificity of CT were found within ranges consistent with the literature. However, the adequacy of CT in invasive and metastatic disease was again found to be low, in line with the literature. Therefore, to prevent misinterpretation, we believe that adding advanced imaging modalities (MRI, PET, EUS) during the preoperative period in addition to CT may help reduce unnecessary laparotomies.

Enucleation is a surgical technique to resect peripheral nerve schwannomas. The procedure has a low risk for postoperative deficit, but a small chance for recurrence, because tumor cells may remain inside the pseudocapsule that is left after resection. Magnetic resonance imaging (MRI) scans are frequently performed after surgery to investigate potential residual tumor, but currently there is little information in the literature on the value of follow-up with MRI. All patients who underwent enucleation of a peripheral nerve schwannoma between October 2013 and June 2022 were included. Postoperative MRI scans (gadolinium-enhanced) made at different time points after the surgery were re-examined for residual enhancement. Patients with residual enhancement were contacted to inform whether symptoms had recurred. A total of 75 schwannoma enucleations in 74 patients were included. The first postoperative MRI scan, performed 3 months after the surgery, showed no residual enhancement in 50 patients. In the remaining 24 patients, another MRI scan was made 1 year after the surgery, which still showed a possible remnant in 11 patients. On the third MRI scan, performed 2 years after enucleation, there were 7 suspected cases (9%). None of these patients had clinical symptoms at a mean postoperative follow-up of 5 years. Our data show that the value of postoperative MRI scans after enucleation of peripheral nerve schwannomas is limited, because residual enhancement in the beginning can be non-specific and the small percentage of patients, that persistently had a potential remnant, were all asymptomatic.

Mohs Micrographic Surgery (MMS) for treatment of melanoma offers several advantages over wide local excision (WLE), including complete histologic margin evaluation, same-day resection and closure, and sparing of healthy tissue in critical anatomic sites. Recently, a large volume of clinical data demonstrating efficacy in MMS treatment of melanoma was published, leading to emerging patient safety considerations of incurred treatment costs, risk of tumor upstaging, and failure of care coordination for sentinel lymph node biopsy (SLNB). MMS offers a safe, effective, and value-based treatment for both melanoma in situ (MIS) and invasive melanoma (IM), particularly with immunohistochemistry use on frozen sections. Compared to wide local excision, MMS treatment demonstrates similar or improved outcomes for local tumor recurrence, melanoma-specific survival, and overall survival at long-term follow-up. Tumor upstaging risk is low, and if present, alteration to clinical management is minimal. Discussion of SLNB for eligible head and neck IM cases should be done prior to MMS. Though challenging, successful multidisciplinary coordination of SLNB with MMS has been demonstrated. Herein, we provide a detailed clinical review of evidence for MMS treatment of cutaneous melanoma and offer recommendations to address current controversies surrounding the evolving paradigm of surgical management for both MIS and invasive melanoma (IM).

IntroductionRigid proctosigmoidoscopy (RP) and flexible sigmoidoscopy (FS) are two modalities commonly used for intraoperative evaluation of colorectal anastomoses. This study seeks to determine whether there is an association between the endoscopic modality used to evaluate colorectal anastomoses and the rate of anastomotic leak (AL), organ space infection, and overall infectious complication.MethodsThe 2012-2018 American College of Surgeons National Surgical Quality Improvement Program database was queried for patients undergoing colorectal anastomoses. Anastomotic evaluation method (RP versus FS) was identified by Current Procedural Terminologycoding and used for group classification. Outcomes measured included AL, organ space infections, and overall infection. Multivariable logistic regression analysis for predicting AL was performed.ResultsWe identified 7100 patients who underwent a colorectal anastomosis with intraoperative endoscopic evaluation. RP was utilized in 3397 (47.8%) and FS in 3703 (52.2%) patients. RP was used more commonly in diverticulitis (44.5% versus 36.2%, P

Abstract Introduction Abdominal trauma in children is a significant health concern that often leads to severe complications and even death. Children experience trauma more frequently than adults, with approximately one in four pediatric patients suffering from serious abdominal injuries. Falls are the leading cause of such trauma among children, which is intriguing considering that most hospital admissions for pediatric abdominal injuries result from blunt force impacts. Method A retrospective cross-sectional analysis of medical records was conducted to examine all patients under the age of 16 who underwent exploratory laparotomy for abdominal trauma between January 1, 2020, and January 1, 2023. The clinical data were gathered using a data extraction sheet from each patient’s medical charts. Information on socio-demographic characteristics, injury mechanisms, clinical conditions at the initial presentation, intraoperative findings and complications, and patient outcomes were collected. Results The study involved a total of 90 patients, consisting of 72 males (80%) and 18 females (20%). The average age of the patients was 10, with a standard deviation of 4.7, ranging from 2 to 16 years. Half of the patients were below the age of 10, accounting for 46 individuals (51%). The causes of the injuries varied among patients below and above the age of 10. However, overall, bullet injuries were the most common cause, accounting for 28 cases (31%), followed by falls in 21 cases (23.3%), horse or donkey kicks in 10 cases (11.1%), stab injuries in 10 cases (11.1%), horn injuries in 7 cases (7.8%), and road traffic accidents in 6 cases (6.7%). Physical assault, blasts, and other types of injuries, such as hen bites and metal rod injuries, were observed in 8 cases (8.9%) of the patients. Fall accidents, horse or donkey kicks, and horn injuries were particularly more common among children below the age of 10, while bullet injuries and stab injuries were most common among those above the age of 10. Conclusion Following abdominal trauma in children, a range of complications may arise, including immediate issues such as infections and hemorrhaging, as well as long-term consequences like impaired organ functionality and psychological distress. In our region, young children are particularly vulnerable to accidents involving falls, kicks from horses or donkeys, and injuries caused by horns. Therefore, it is crucial to educate parents about these hazards. Additionally, providing appropriate guidance on firearm safety is essential for individuals who possess such weapons.

Abstract Purpose To compare the clinical outcomes between nonsurgical and surgical treatment of distal radius fracture. Methods We performed a systematic literature search by using multiple databases, including Medline, PubMed, and Cochrane. All databases were searched from the earliest records through February 2023. The study compared nonsurgical versus surgical treatment of distal radius fractures and included only randomized controlled trials (RCTS). Results There were seventeen randomized controlled trials retrieved. A total of 1730 patients were included: 862 in the nonsurgical group and 868 in the surgical group. The results showed a significant reduction in DASH score with surgical treatment (WMD 3.98, 95% CI (2.00, 5.95), P

Background: Anxiety before surgery is one of the most challenging aspects of preoperative care. Preoperative anxiety has a number of postoperative complications. There are only a few studies that report on preoperative anxiety in surgical patients in Ethiopia, and their prevalence differs from one study to the next. Objective: The aim of this study was to assess the level of preoperative anxiety and associated factors among surgical patients admitted at public hospitals in southern Ethiopia. Methods: From July to August 2022, a facility-based cross-sectional study was conducted among patients admitted to surgical wards at public hospitals. Data collection was conducted using a pretested, structured questionnaire administered by an interviewer. Preoperative anxiety was assessed using the State-Trait Anxiety Inventory scale. The data were coded and entered in Epi Data Version 4.6, then exported to Statistical Package for Social Sciences version 25 for analysis. To describe the study variables, descriptive statistics were used. The associated factors were then identified using bivariate and multivariate logistic regression analyses. Results were declared at a p-value of less than 0.05 based on an adjusted odds ratio with a 95% confidence interval. Result: A total of 220 patients were enrolled, with a 99.5% response rate. The observed preoperative anxiety level was 57.5% (95%CI: 54.63–62.35). High preoperative anxiety was associated with no formal educational status (AOR: 3.75; 95%CI = 1.36, 10.39), fear of death (AOR =2.01; 95%CI = 1.09, 3.73), fear of waking up in middle of surgery (AOR =3.42; 95%CI =1.19, 9.77), fear of postoperative pain (AOR = 2.56; 95%CI = 1.15, 5.74). Conclusion: This study found that five out of ten patients scheduled for surgery in public hospitals had high levels of preoperative anxiety. Anxiety levels were associated with factors such as the educational status of respondents, fear of death, fear of waking up in the middle of surgery, and fear of postoperative pain. Preoperative anxiety assessments should be conducted regularly in each hospital, and appropriate anxiety-reducing methods must be implemented. [ABSTRACT FROM AUTHOR]

Background: The COVID‐19 pandemic disrupted the provision of surgical services in Australia. To prepare for a surge of COVID‐19 patients, elective surgery was mandatorily reduced or ceased at multiple timepoints in Australian states between 2020 and 2022. Operative exposure is a critical component of surgical training in general surgery, and readiness for practice is an ongoing priority. However, the impact of COVID‐19 on operative exposure in Australian General Surgical Trainees (AGST) has not been quantified. Methods: This study was a retrospective longitudinal cohort study using de‐identified operative logbook data for Australian General surgical Trainees (AGST) from the Royal Australasian College of Surgeons (RACS) Morbidity and Audit Logbook Tool (MALT) system between February 2019 and July 2021. Bivariate analysis was used to determine the impact of COVID‐19 on general surgical trainees' exposure to operative surgery and trainees' operative autonomy. Results: Data from 1896 unique 6‐month training terms and 543 285 surgical cases was included over the data collection period. There was no statistically significant impact of the COVID‐19 pandemic on AGST operative exposure to major, minor operations, endoscopies, or operative autonomy. Conclusions: The impact of COVID‐19 on surgical trainees globally has been significant. Although this study does not assess all aspects of surgical training, this data demonstrates that there has not been a significant impact of the pandemic on operative exposure or autonomy of AGST.

BACKGROUND: High-risk alcohol use is a common preventable risk factor for postoperative complications, admission to intensive care, and longer hospital stays. Short-term abstinence from alcohol use (2 to 4 weeks) prior to surgery is linked to a lower likelihood of postoperative complications. OBJECTIVE: The study aimed to explore the acceptability and feasibility of 2 brief counseling approaches to reduce alcohol use in elective surgical patients with high-risk alcohol use in the perioperative period. METHODS: A semistructured interview study was conducted with a group of high responders (who reduced alcohol use ≥50% postbaseline) and low responders (who reduced alcohol use by ≤25% postbaseline) after their completion of a pilot trial to explore the acceptability and perceived impacts on drinking behaviors of the 2 counseling interventions delivered remotely by phone or video call. Interview transcripts were analyzed using thematic analysis. RESULTS: In total, 19 participants (10 high responders and 9 low responders) from the parent trial took part in interviews. Three main themes were identified: (1) the intervention content was novel and impactful, (2) the choice of intervention modality enhanced participant engagement in the intervention, and (3) factors external to the interventions also influenced alcohol use. CONCLUSIONS: The findings support the acceptability of both high- and low-intensity brief counseling approaches. Elective surgical patients are interested in receiving alcohol-focused education, and further research is needed to test the effectiveness of these interventions in reducing drinking before and after surgery.

Introduction: Diabetes mellitus is a major public health problem in India. A Diabetic Foot Ulcer (DFU) is characterised by a full-thickness wound, skin necrosis, or gangrene below the ankle brought on by peripheral neuropathy or peripheral artery disease in diabetic patients. Numerous classification schemes have been put forth to classify and forecast the clinical outcomes of DFUs. The Perfusion, Extent, Depth, Infection and Sensation Score (PEDIS) classification system was developed to objectively categorise and define DFUs, facilitating communication between healthcare providers. Aim: To determine the utility of the PEDIS score in predicting the outcomes of patients with DFUs. Materials and Methods: The present single-centre prospective cohort study was conducted in the Department of General Surgery, Tezpur Medical College and Hospital, Tezpur, Assam, India, from August 1, 2022 to January 30, 2023, involving 60 patients. A PEDIS score was calculated and recorded for each patient. Patients were then classified into low-score (0-7) or high-score (8-12) groups and followed-up for six months. Outcomes were categorised as healed, unhealed, amputated, or deceased. Categorical data were presented as percentages and compared using the Chi-square test. The Receiver Operating Characteristic (ROC) curve was utilised to determine the cut-off value. A p-value

Background: Proximal humerus fractures are the third most common fracture type for patients between the ages of 65 and 89 and occur more frequently in women than men. Given the variety of surgical treatments for proximal humerus fractures, the aim of this study was to (1) report United States national volume and incidence estimates for surgical management of proximal humerus fractures to better understand the changing practice over the past decade and (2) to analyze differences in volume and incidence among age groups, sex, and geographic region. Methods: Using IBM Marketscan national database, all patients that underwent open reduction internal fixation (ORIF), hemiarthroplasty, or reverse total shoulder arthroplasty (RTSA) between 2010 and 2019 were identified with Current Procedural Terminology codes. The dataset was further stratified to identify patients treated for proximal humerus fractures. IBM Marketscan provided discharge weights that were used to determine estimated national annual volumes of each procedure in IBM SPSS Statistics software (IBM Corp., Armonk, NY, USA). Volume and incidence were adjusted per 1,000,000 persons and calculated for subgroups according to age group, sex, and geographical region. The United States Census Bureau annual population data was used for all incidence calculations. Results: Over the past decade, the total volume and incidence of surgically treated proximal humerus fractures increased by 13% and 5%, respectively. Although overall incidence decreased, ORIF remained the most common surgical treatment. The greatest decrease in volume and incidence of ORIF occurred in patients ≥75. The incidence of ORIF treatment increased in the South and West while it decreased in the Northeast and Midwest. Total volume and incidence of HA decreased between 2010 and 2019 and this trend remained among all subgroups. Total volume and incidence of RTSA increased by over 300%. The incidence of males and females receiving RTSA increased by 266% and 320%, respectively. Volume and incidence of RTSA increased across all age groups. Volume and incidence of RTSA increased in the Midwest, South, and Western regions while it remained unchanged in the Northeast. Conclusion: Surgical management trends of proximal humerus fractures have changed greatly over the past decade. ORIF remains the most common surgical treatment for proximal humerus fractures. HA has fallen out of favor while RTSA has seen significant increases in usage across sex, age groups, and geographic regions. These trends represent a change in practice for treating proximal humerus fractures by considering all patient and fracture characteristics when opting for surgical management.

Vascularized Composite Tissue Allotransplantation (VCA) allows replacement of lost body parts from brain-dead donors. These surgeries are laborious, time-intensive, and require vast planning. With the advent of better immunosuppressants, VCA will increasingly play an important role in the reconstructive field. In this paper, the authors share their standard operating protocol created after much deliberation.

(1) Background: Dislocations of the trapeziometacarpal joint (TMC) are uncommon in children and adolescents. Only a few isolated cases are reported in the literature. Therapeutic guidance is minimal and inconclusive. (2) Methods: The authors present four patients treated for this unusual lesion. We evaluated the evolution according to treatment, age, patient activity, and quickDASH. Despite the clear limitation of the small number of patients, it is relevant to try to better understand this lesion and its evolution. A systematic review of the literature was also conducted. (3) Results: This is the largest published series of TMC dislocations in children and adolescents. Patients included a 12-year-old girl treated conservatively with a poor quickDASH; a 9-year-old girl treated surgically with the Eaton–Littler technique for a new dislocation with a partially modified quickDASH; a 13-year-old boy with two necessary closed reductions for a new dislocation and a very good final quickDASH; and a 12-year-old boy treated with closed reduction and percutaneous fixation with excellent final results with quickDASH. (4) Conclusions: In the absence of scientific evidence, conservative treatment and ligament reconstruction did not provide good functionality. In contrast, closed reduction with percutaneous fixation provided excellent results. Therefore, the authors would recommend closed reduction and percutaneous needle fixation as an elective method to treat TMC dislocations in pediatric and adolescent patients. [ABSTRACT FROM AUTHOR]

Objective: To determine signalment, injury type, trauma severity score, and outcome of canine trauma patients undergoing surgical (emergency room [ER] or operating room [OR]) and nonsurgical treatment in addition to time to surgery, specialty services involved, and cost in the OR surgery population. Design: Retrospective evaluation of medical record and hospital trauma registry data on canine trauma cases. Setting: University teaching hospital. Animals: One thousand six hundred and thirty dogs presenting for traumatic injury between May 2017 and July 2020. Interventions: None. Measurements and Main Results: Demographics and outcome were compared for canine trauma patients undergoing OR surgery (12.8%, 208/1630), ER surgery (39.1%, 637/1630), or no surgical intervention (48.2%, 785/1630). Among the 2 surgical groups, 98.9% (836/845) survived to discharge compared with 92.2% (724/785) of the nonsurgical group (P < 0.0001). The OR surgical group had significantly higher median Animal Trauma Triage scores (2 vs 1, P < 0.0001) and median days in hospital (2 vs < 1, P < 0.0001) compared with the other groups. For the OR surgical cohort, electronic medical records were reviewed to determine the specialty surgery service involved, time to and duration of anesthesia and surgery, and visit cost. The most common surgery services involved were orthopedics (45.2%, 94/208) and general surgery (26.9%, 56/208). Neurology and general surgery cases required the longest median length of stay in hospital, and ophthalmology and dentistry cases required the shortest. The median cost of visit was highest in neurology ($10,032) and lowest in ophthalmology ($2305) and dentistry ($2404). Conclusions: Surgical intervention in canine trauma patients appears to be associated with higher survival rates, and among the surgery groups, mortality was highest in the ER and general surgery groups. OR surgical intervention, in particular general surgery and neurology, was associated with increased length of hospitalization, increased cost, and higher Animal Trauma Triage scores.

Objective: Although regurgitant mitral valves can be repaired through surgical or transcatheter approaches, contemporary comparative outcomes are limited with the impact of residual and recurrent mitral regurgitation (MR) on clinical outcomes being poorly defined. We hypothesized that moderate (2+) or greater residual or recurrent (RR) MR—regardless of type of repair—predicts worse clinical outcomes. Methods: Our institutional experience of 660 consecutive patients undergoing mitral valve repair (2015-2021) consisting of 393 surgical mitral valve repair (SMVr) and 267 transcatheter edge-to-edge mitral valve repair (TEER) was studied. The echocardiographic impact of RRMR (2+) following both SMVr and TEER on death and reintervention was evaluated. Results: Patients averaged 67.8 ± 14.2 years (SMVr = 63.8 ± 13.3 vs 73.6 ± 13.6, P

Splenic artery pseudoaneurysm is a rare and potentially fatal condition. In the present report, we describe the case of a 50-year-old woman with chronic pancreatitis who presented with worsening abdominal pain. Computed tomography demonstrated a 3.5-cm splenic artery pseudoaneurysm of the mid-splenic artery. The patient underwent attempted endovascular repair of the pseudoaneurysm that was unsuccessful. Open conversion revealed an inaccessible splenic artery due to chronic pancreatitis that resulted in dense retroperitoneal fibrosis, and repair was achieved via direct thrombin injection under ultrasound guidance of the pseudoaneurysm and splenectomy. The patient recovered well, and computed tomography at 3 days postoperatively revealed complete thrombosis of the pseudoaneurysm.

BackgroundAlthough there is extensive literature on robotic total intracorporeal anastomosis (TICA) for right colon resection, left total ICA using the da Vinci Xi robotic platform has only been described in short case series previously. In this study, we report on the largest cohort of robotic left total ICA, provide a description of our institution's techniques, and compare outcomes to robotic left partial extracorporeal anastomosis (PECA).MethodsPatients who underwent robotic left colectomy for any underlying pathology from July 1, 2016 through April 30, 2020 were identified by procedure code. A technical description is provided for two unique techniques performed at our institution. Outcomes included operative time, length of stay, supply cost, post-operative ileus, post-operative morbidity and mortality and need for complete mobilization of the splenic flexure.ResultsFrom a review of our institution's data, 83 robotic TICA cases were identified and 76 robotic PECA cases were identified. Common procedures included low anterior resection, sigmoidectomy, left hemicolectomy, and rectopexy with resection. TICA was associated with significantly shorter intraoperative time compared to PECA.ConclusionsOur series shows that TICA is a safe and feasible technique that does not increase the risk of adverse outcomes. Using either the anvil-forward or anvil-backward technique, we were able to reliably reproduce this method in a total of 83 patients undergoing left colon resection for either benign or malignant diseases.

BackgroundThe time course and longitudinal impact of the COVID -19 pandemic on surgical education(SE) and learner well-being (LWB)is unknown.Material and methodsCheck-in surveys were distributed to Surgery Program Directors and Department Chairs, including general surgery and surgical specialties, in the summer and winter of 2020 and compared to a survey from spring 2020.

ObjectiveTo describe the development and implementation of virtual vascular surgery rotations among 6 integrated vascular surgery programs.DesignA collaborative teleconference retrospectively discussing 6 independently developed virtual vascular surgery rotations to make a framework for future use.SettingUniversity of California Davis initiated a joint teleconference among the various integrated vascular surgery programs.ParticipantsVascular surgery faculty and residents from 6 programs participated in the teleconferences and drafting of a framework for building a virtual vascular surgery rotation.ResultsFour specific domains were identified in discussing the framework to build a virtual vascular surgery rotation: planning, development, curriculum, and feedback. Each domain has specific aspects in making a virtual rotation that has applicability to other surgical rotations that seek to do the same.ConclusionVirtual vascular surgery rotations are feasible and important; these electives can be established and implemented successfully with appropriate planning and consideration. This work hopes to help programs navigate this new space in education by making it more transparent and highlighting potential pitfalls.

Background and objectivesThough patient factors are frequently linked to hemodialysis vascular access selection and outcomes, variability by surgeon and surgeon specialty may play a role as well. The objective of this study is to examine the extent to which individual surgeons influence selection of vascular access type, removal of tunneled hemodialysis catheter (THC), and repeat vascular access.Design, setting, participants, & measurementsA national claims database was used to identify patients initiating hemodialysis via a THC between 2011 and 2017. Likelihood of repeat AVF/AVG was analyzed using mixed-effects logistic regression. Time from initial arteriovenous fistula (AVF)/graft (AVG) to THC removal and time to repeat AVF/AVG were analyzed using Weibull proportional hazard models. Individual surgeon identifier served as the random effect in all models.Results6,908 AVF/AVG met the inclusion criteria: 5366 (78%) AVF and 1,542 (22%) AVG. Surgeon specialty only had a significant influence on access type, with vascular surgeons having 26% greater odds of performing AVG compared to general surgeons (P = 0.006). Relative to the other independent variables, individual surgeon identifier had the greatest magnitude of effect on access type (median odds ratio, 2.36; 95% CI, 2.09-2.72). Individual surgeon identifier had the second greatest magnitude of effect likelihood of THC removal (median hazard ratio, 1.66; 95% CI, 1.58-1.77) and second access (median hazard ratio, 1.83; 95% CI, 1.66-2.05), in both cases second only to the effect of AVG, which was associated with greater likelihood of THC removal (hazard ratio 1.91; 95% CI, 1.77-2.07) and lower likelihood of second access (hazard ratio 0.44; 95% CI, 0.38-0.52).ConclusionIndividual surgeons are associated with greater variation in vascular access type and likelihood of repeat access than surgeon specialty and measurable patient demographics/co-morbidities. Future research should focus on identifying which surgeon factors are associated with improved outcomes.

Ulcerative colitis (UC) is an autoimmune-mediated colitis which can present in varying degrees of severity and increases the individual's risk of developing colon cancer. While first-line treatment for UC is medical management, surgical treatment may be necessary in up to 25-30% of patients. With an increasing armamentarium of biologic therapies, patients are presenting for surgery much later in their course, and careful understanding of the complex interplay of the disease, its management, and the patient's overall health is necessary when considering he appropriate way in which to address their disease surgically. Surgery is generally a total proctocolectomy either with pelvic pouch reconstruction or permanent ileostomy; however, this may need to be spread across multiple procedures given the complexity of the surgery weighed against the overall state of the patient's health. Minimally invasive surgery, employing either laparoscopic, robotic, or transanal laparoscopic approaches, is currently the preferred approach in the elective setting. There is also some emerging evidence that appendectomy may delay the progression of UC in some individuals. Those who treat these patients surgically must also be familiar with the numerous potential pitfalls of surgical intervention and have plans in place for managing problems such as pouchitis, cuffitis, and anastomotic complications.

Objective: We examined long-term health outcomes associated with new persistent opioid use after surgery and hypothesized that patients with new persistent opioid use would have poorer overall health outcomes compared with those who did not develop new persistent opioid use after surgery. Background: New persistent opioid use is a common surgical complication. Long-term opioid use increases risk of mortality, fractures, and falls; however, less is known about health care utilization among older adults with new persistent opioid use after surgical care. Methods: We analyzed claims from a 20% national sample of Medicare beneficiaries ≥65 years undergoing surgery between January 1, 2009, and June 30, 2019. We estimated associations between new persistent use and subsequent health events between 6 and 12 months after surgery, including mortality, serious fall/fall-related injury, and respiratory or opioid/pain-related readmission/emergency department (ED) visits using a Cox proportional hazards model to estimate mortality and multivariable logistic regression for the remaining outcomes, adjusting for demographic/clinical characteristics. Our primary outcome was mortality within 6 to 12 months after surgery. Secondary outcomes included falls and readmissions or ED visits (respiratory, pain related/opioid related) within 6 to 12 months after surgery. Results: Of 229,898 patients, 6874 (3.0%) developed new persistent opioid use. Compared with patients who did not develop new persistent opioid use, patients with new persistent opioid use had a higher risk of mortality (hazard ratio 3.44, CI, 2.99–3.96), falls [adjusted odds ratio (aOR): 1.21, 95% CI, 1.05–1.39], and respiratory-related (aOR: 1.67, 95% CI, 1.49–1.86) or pain-related/opioid-related (aOR: 1.68, 95% CI, 1.55–1.82) readmissions/ED visits. Conclusions: New persistent opioid use after surgery is associated with increased mortality and poorer health outcomes after surgery. Although the mechanisms that underlie this risk are not clear, persistent opioid use may also be a marker for greater morbidity requiring more care in the late postoperative period. Increased awareness of individuals at risk for new persistent use after surgery and close follow-up in the late postoperative period is critical to mitigate the harms associated with new persistent use.

BackgroundIndocyanine green fluoroscopy has been shown to improve anastomotic leak rates in early phase trials.ObjectiveWe hypothesized that the use of fluoroscopy to ensure anastomotic perfusion may decrease anastomotic leak after low anterior resection.DesignWe performed a 1:1 randomized controlled parallel study. Recruitment of 450 to 1000 patients was planned over 2 years.SettingsThis was a multicenter trial.PatientsIncluded patients were those undergoing resection defined as anastomosis within 10 cm of the anal verge.InterventionPatients underwent standard evaluation of tissue perfusion versus standard in conjunction with perfusion evaluation using indocyanine green fluoroscopy.Main outcome measuresPrimary outcome was anastomotic leak, with secondary outcomes of perfusion assessment and the rate of postoperative abscess requiring intervention.ResultsThis study was concluded early because of decreasing accrual rates. A total of 25 centers recruited 347 patients, of whom 178 were randomly assigned to perfusion and 169 to standard. The groups had comparable tumor-specific and patient-specific demographics. Neoadjuvant chemoradiation was performed in 63.5% of perfusion and 65.7% of standard (p > 0.05). Mean level of anastomosis was 5.2 ± 3.1 cm in perfusion compared with 5.2 ± 3.3 cm in standard (p > 0.05). Sufficient visualization of perfusion was reported in 95.4% of patients in the perfusion group. Postoperative abscess requiring surgical management was reported in 5.7% of perfusion and 4.2% of standard (p = 0.75). Anastomotic leak was reported in 9.0% of perfusion compared with 9.6% of standard (p = 0.37). On multivariate regression analysis, there was no difference in anastomotic leak rates between perfusion and standard (OR = 0.845 (95% CI, 0.375-1.905); p = 0.34).LimitationsThe predetermined sample size to adequately reduce the risk of type II error was not achieved.ConclusionsSuccessful visualization of perfusion can be achieved with indocyanine green fluoroscopy. However, no difference in anastomotic leak rates was observed between patients who underwent perfusion assessment versus standard surgical technique. In experienced hands, the addition of routine indocyanine green fluoroscopy to standard practice adds no evident clinical benefit.

Se planificó el reclutamiento de 450-1000 pacientes durante 2 años.AMBITO:Multicéntrico.PACIENTES:Pacientes sometidos a resección definida como una anastomosis dentro de los 10cm del margen anal.INTERVENCIÓN:Pacientes que se sometieron a la evaluación estándar de la irrigación tisular contra la estándar en conjunto con la valoración de la irrigación mediante fluoroscopia con verde indocianina.PRINCIPALES VARIABLES EVALUADAS:El principal resultado fue la fuga anastomótica, y los resultados secundarios fueron la evaluación de la perfusión y la tasa de absceso posoperatorio que requirió intervención.RESULTADOS:Este estudio se cerró anticipadamente debido a la disminución de las tasas de acumulación. Un total de 25 centros reclutaron a 347 pacientes, de los cuales 178 fueron, de manera aleatoria, asignados a perfusión y 169 a estándar. Los grupos tenían datos demográficos específicos del tumor y del paciente similares. Recibieron quimio-radioterapia neoadyuvante el 63,5% de la perfusión y el 65,7% del estándar (p> 0,05). La anastomosis estuvo en un nivel promedio de 5,2 + 3,1 cm en perfusión en comparación con 5,2 + 3,3 cm en estándar (p> 0,05). Se reportó una visualización suficiente de la perfusión en el 95,4% de los pacientes del grupo de perfusión. El absceso posoperatorio que requirió tratamiento quirúrgico fue de 5,7% de los perfusion y en el 4,2% del estándar (p = 0,75). Se informó fuga anastomótica en el 9,0% de la perfusión en comparación con el 9,6% del estándar (p = 0,37). En el análisis de regresión multivariante, no hubo diferencias en las tasas de fuga anastomótica entre la perfusión y el estándar (OR 0,845; IC del 95% (0,375; 1,905); p = 0,34).LIMITACIONES:No se logró el tamaño de muestra predeterminado para reducir satisfactoriamente el riesgo de error tipo II.CONCLUSIÓN:Se puede obtener una visualización adecuada de la perfusión con ICG-F. Sin embargo, no se observaron diferencias en las tasas de fuga anastomótica entre los pacientes que se sometieron a evaluación de la perfusión versus la técnica quirúrgica estándar. En manos expertas, agregar ICG-F a la rutina de la práctica estándar no agrega ningún beneficio clínico evidente. Consulte Video Resumen en http://links.lww.com/DCR/B560.

The management of symptomatic giant hepatic hemangiomas (> 10 cm) varies in the literature. Multiple interventional approaches have been described including surveillance, embolization, enucleation, and resection based on tumor size, location, relationship to vascular and biliary structures, and the quality and quantity of the functional liver remnant. Resection is often performed as a last resort due to the risk of major hemorrhage. Preoperative arterial embolization is an option; however, many patients will experience severe pain, fever, transaminitis, acidosis, recanalization, and collateral inflow that limit its utility. Furthermore, patients require post-procedure inpatient observation, and there is no consensus on the appropriate time interval between procedures. We present and demonstrate a technique in the video that utilizes a hybrid operating room with on-table angiogram capabilities to perform hemangioma inflow embolization and immediate hepatic resection under the same anesthesia in a single procedure. Combining on-table embolization with immediate resection avoids many of the pitfalls of preoperative embolization, while enhancing the safety of the resection by decreasing the size of the tumor, enabling compressibility, and facilitating exposure of the vascular inflow and outflow. It is an efficient use of hospital resources and eliminates an intervening hospital admission. We have found it to be a preferred approach to enhance the safety and feasibility of resection for massive hepatic hemangiomas with minimal intraoperative blood loss and reduced risk.

BackgroundIt is increasingly recognized that non-opioid analgesia is an important analgesia in the perioperative period. Specifically, NSAIDs (nonsteroidal anti-inflammatory drugs) have been touted as an adjunct, or even replacement, for opioids. However, uptake of NSAIDs has been slow due to concern for side effects, including bleeding. We sought to understand the risk of bleeding caused by NSAIDs in the perioperative period.Study designA physician-librarian team performed a search of electronic databases (MEDLINE, EMBASE), using search terms covering the targeted intervention (use of NSAIDs) and outcomes of interest (surgical complications, bleeding), limited to English language articles of any date. We performed a systematic review and meta-analysis of the data.ResultsA total of 2,521 articles were screened, and 229 were selected on the basis of title and abstract for detailed assessment. Including reference searching, 74 manuscripts met inclusion criteria spanning years 1987-2019. These studies included 151,031 patients. Studies included 12 types of NSAIDs, the most common being ketorolac, diclofenac, and ibuprofen, over a wide-range of procedures, from otorhinolaryngology (ENT), breast, abdomen, plastics, and more. More than half were randomized control trials. The meta-analyses for hematoma, return to the operating room for bleeding, and blood transfusions showed no difference in risk in any of 3 categories studied between the NSAID vs non-NSAID groups (p = 0.49, p = 0.79, and p = 0.49, respectively). Quality scoring found a wide range of quality, with scores ranging from lowest quality of 12 to highest quality of 25, out of a total of 27 (average = 16).ConclusionsNSAIDs are unlikely to be the cause of postoperative bleeding complications. This literature covers a large number of patients and remains consistent across types of NSAIDs and operations.

Background: Small bowel obstruction (SBO) is common and its management has evolved in recent years. Study design: The literature describing adhesive small bowel obstruction (aSBO) treatment was reviewed, and a formal systematic review was performed to identify publications reporting results of aSBO treatment without NGTs. Results: The annual rate of hospital admission for SBO in the US has increased, with 340,100 admissions in 2019 alone. SBO is usually treated with bowel rest, intravenous hydration and NGT placement. In recent years, water soluble contrast (WSC) has been used as a cathartic to simulate bowel function and may reduce hospital length of stay (HLOS) by 1.95 days (95%CI 0.56–3.3). There were 3 articles of the initial 1650 screened that reported outcomes of SBO treatment without NGTs. These articles included 759 patients, of whom 272 (36%) with aSBO were managed successfully without NGTs. When comparing outcomes to patients who did receive NGT decompression, there were no significant differences in operative rates (28.6% v 16.5%, risk ratio 1.34, 95% CI 1.0, 1.8). Mortality and rates of bowel resection were also not affected by NGT decompression (risk ratio 1.98, 95% CI 0.43, 9.10 and risk ratio 1.56, 95% CI 0.92, 2.65, respectively). Conclusion: SBO is a common disease process with increasing annual incidence. Use of WSC stimulates the bowel and may reduce HLOS. Modern aSBO treatment protocols should include NGT decompression with consideration of WSC administration. Selection of patients for treatment without NGT decompression requires further investigation.

Background: Digit replantation affords the opportunity to restore hand function following amputation. To date, however, few studies have evaluated functional outcomes following replantation. Therefore, it was the objective of this study to perform a meta-analysis to better characterize the predictors of hand function. Methods: A literature search was performed using the PubMed database to identify studies that focused on digit amputation/replantation and functional outcomes. Studies were evaluated for patient- and injury-related factors and their respective effects on clinical outcomes of sensation, grip strength, and Disabilities of the Arm, Shoulder, and Hand (DASH) scores. Statistical analysis was conducted across the pooled data set to identify significant trends. Results: Twenty-eight studies representing 618 replanted digits were included in this study. We found the average grip strength was 78.7% (relative to contralateral), the average 2-point discrimination (2PD) was 7.8 mm, and the average DASH score was 12.81. After conducting statistical analysis, we found patients with more proximal injuries had lower grip strength scores (P < .05). We found 2PD scores were influenced by age, mechanism of injury, and amputation level (P < .05). Finally, we found DASH scores after replantation were predicted by mechanism of injury and level of amputation (P < .05). The following variables did not influence outcomes: gender, tobacco use, ischemia time, and digit number. Conclusions: Digit replant does not restore premorbid hand function but does result in adequate hand function. Expected functional outcomes following replant should be considered in the decision-making process. These data can help risk-stratify patients, guide postreplant expectations, and influence the decision for replantation.

BackgroundThe COVID-19 pandemic disrupted the delivery of surgical services. The purpose of this communication was to report the impact of the pandemic on surgical training and learner well-being and to document adaptations made by surgery departments.Study designA 37-item survey was distributed to educational leaders in general surgery and other surgical specialty training programs. It included both closed- and open-ended questions and the self-reported stages of GME during the COVID-19 pandemic, as defined by the ACGME. Statistical associations for items with stage were assessed using categorical analysis.ResultsThe response rate was 21% (472 of 2,196). US stage distribution (n = 447) was as follows: stage 1, 22%; stage 2, 48%; and stage 3, 30%. Impact on clinical education significantly increased by stage, with severe reductions in nonemergency operations (73% and 86% vs 98%) and emergency operations (8% and 16% vs 34%). Variable effects were reported on minimal expected case numbers across all stages. Reductions were reported in outpatient experience (83%), in-hospital experience (70%), and outside rotations (57%). Increases in ICU rotations were reported with advancing stage (7% and 13% vs 37%). Severity of impact on didactic education increased with stage (14% and 30% vs 46%). Virtual conferences were adopted by 97% across all stages. Severity of impact on learner well-being increased by stage-physical safety (6% and 9% vs 31%), physical health (0% and 7% vs 17%), and emotional health (11% and 24% vs 42%). Regardless of stage, most but not all made adaptations to support trainees' well-being.ConclusionsThe pandemic adversely impacted surgical training and the well-being of learners across all surgical specialties proportional to increasing ACGME stage. There is a need to develop education disaster plans to support technical competency and learner well-being. Careful assessment for program advancement will also be necessary. The experience during this pandemic shows that virtual learning and telemedicine will have a considerable impact on the future of surgical education.

Background: Acne often worsens in transmasculine patients who are on prolonged testosterone therapy. Isotretinoin is an oral retinoid used in the treatment of severe or refractory cases of acne, but it has the potential to cause delayed wound healing. Transmasculine patients may potentially be prescribed treatment for acne with isotretinoin while also planning to undergo chest masculinization surgery. Objective: This scoping review aims to determine whether isotretinoin has a negative impact on postoperative healing in transmasculine patients undergoing chest masculinization surgery. Methods: A scoping review was performed using the PubMed and Ovid databases. A total of 16 publications were selected for inclusion. Results: Acne tends to peak in transmasculine patients six months after initiation of testosterone treatment. Severe cases can be treated with isotretinoin; however, acne may recur once treatment is discontinued, given ongoing hormone therapy. There is little-to-no evidence in the medical literature regarding perioperative use of isotretinoin specifically among transmasculine patients undergoing chest masculinization surgery. In general, however, recent studies have found no evidence of increased hypertrophic scars or keloids in patients taking isotretinoin. Conclusion: Further studies are required to strengthen the current evidence that suggests that isotretinoin does not need to be discontinued before or after incisional or excisional surgeries, including chest masculinization surgery in transmasculine patients.

Background: The present study aimed to assess variables associated to ICU-mortality among patients admitted to surgical intensive care unit in Ethiopia. Methods: A Hospital-based retrospective follow-up study was conducted on all patients who were admitted to the surgical intensive care unit. Data were extracted from patients' charts with a pretested data extraction tool, entered into Epi-data 4.6.0, and analyzed with STATA- 14. Bivariate and multivariate Cox proportional hazards regression models were fitted. Results: Of the total study participants (388), 148 (38.1%) patients admitted to the surgical intensive care unit died during the follow-up period with a median survival time of 11 days. Potassium level < 3.5 mmol/L (adjusted hazard ratio (AHR): 3.46, 95% CI (1.83 6.55), potassium level > 5.0 mmol/L (AHR:2.41, 95% CI (1.29–4.51), hypoxia (AHR:1.66, 95% CI (1.10–2.48), Glasgow Coma Scale (GCS) score < 9 (AHR: 4.06, 95% CI (1.51–10.89), mechanical ventilation (AHR:12, 95%CI (3–45), absence of thromboprophylaxis (AHR:10.8,95% CI (6.04–19.29), absence of enteral feeding (AHR:3.56, 95% CI (2.20–5.78) were variables associated with ICU-mortality among patients admitted to surgical intensive care unit. Conclusions: The overall ICU-mortality of patients admitted to our surgical intensive care unit was higher compared to patients admitted to similar intensive care unit in developed countries. The variables associated to ICU-mortality among patients admitted to surgical intensive care unit were abnormal serum potassium level, lower GCS score, mechanical support, hypoxia, absence of thromboprophylaxis, and enteral feeding.

Purpose: To define the impact of the COVID-19 outbreak on hospital surgical activity and assess the incidence of perioperative COVID-19 within two protocolized screening pathways for elective and non-elective surgery. Methods: We conducted a prospective cohort study of adults undergoing surgery during the COVID-19 outbreak. The elective pathway included telephone surveys and a quantitative polymerase-chain-reaction test (RT-PCR) only for patients who were asymptomatic and at low risk of infection. Only patients with negative screening underwent surgery. In the non-elective pathway, preoperative screening was performed during the hospital admission. Results: Among 835 patients considered for the elective pathway, 725 had negative RT-PCR results and underwent surgery. This reflects an 83% reduction in surgical activity from 2019. Moreover, 596 patients underwent non-elective surgery, representing a 28% reduction. Preoperatively, 39 patients (6.5%) tested positive for SARS-CoV-2 and underwent surgery through the non-elective pathway, vs. none in the elective pathway (p < 0.001). Postoperatively, 1.4% of elective surgery patients and 2.2% of non-elective surgery patients tested positive (p > 0.05). Mortality was higher in non-elective surgery (0.6% vs. 2.9%, p < 0.001) and in patients with COVID-19 (0% vs. 14%, p < 0.001). Conclusions: The low incidence of COVID-19 in elective surgeries during the outbreak demonstrates the importance and effectiveness of preoperative screening, combining surveys and RT-PCR.

Contrast enema is the gold standard technique for evaluating a pelvic anastomosis (PA) prior to ileostomy closure. With the increasing use of flexible endoscopic modalities, the need for contrast studies may be unnecessary. The objective of this study is to compare flexible endoscopy and contrast studies for anastomotic inspection prior to defunctioning stoma reversal. Patients with a protected PA undergoing ileostomy closure between July 2014 and June 2019 at our institution were retrospectively identified. Demographics and clinical outcomes in patients undergoing preoperative evaluation with endoscopic and/or contrast studies were analyzed. We identified 207 patients undergoing ileostomy closure. According to surgeon's preference, 91 patients underwent only flexible endoscopy (FE) and 100 patients underwent both endoscopic and contrast evaluation (FE + CE) prior to reversal. There was no significant difference in pelvic anastomotic leak (2.2% vs. 1%), anastomotic stricture (1.1% vs. 6%), pelvic abscess (2.2% vs. 3.0%), or postoperative anastomotic complications (4.4% vs. 9%) between groups FE and FE + CE (P > .05). Flexible endoscopy alone appears to be an acceptable technique for anastomotic evaluation prior to ileostomy closure. Further studies are needed to determine the effectiveness of different diagnostic modalities for pelvic anastomotic inspection.

Patient satisfaction measures and the opioid epidemic have highlighted the need for effective perioperative pain management. Multimodal analgesia, including non-steroidal anti-inflammatory drugs (NSAIDs), have been shown to maximize pain relief and reduce opioid consumption, but are also associated with potential perioperative bleeding risks.A multidisciplinary panel conducted a clinical appraisal of bleeding risks associated with perioperative NSAID use. The appraisal consisted of review and assessment of the current published evidence related to the statement "In procedures with high bleeding risk, NSAIDs should always be avoided perioperatively." We report the presented literature and proceedings of the subsequent panel discussion and national pilot survey results. The authors' assessment of the statement based on current evidence was compared to the attempted national survey data, which revealed a wide range of opinions reflecting the ongoing debate around this issue in a small number of respondents.The appraisal concluded that caution is warranted with respect to perioperative use of NSAIDs. However, summarily excluding NSAIDs from perioperative use based on potential bleeding risks would be imprudent. It is recommended that NSAID use be guided by known patient- and procedure-specific factors to minimize bleeding risks while providing effective pain relief.

Introduction: The description of the Anaplastic Large Cell Lymphoma and the explantation surgery resulted in an increase of histopathological exams in breast implant removing surgery. Methods: 251 pathology requests were studied. The following data from the medical requests were analyzed: gender, age, type of surgery, number of specimens containers sent, laterality, anatomical and spatial location, clinical history, signs and symptoms, previous radiotherapy, previous chemotherapy, diagnostic hypothesis, previous surgeries, and reference to previous breast exams. Results: The mean age was 43 years old. Laterality was not mentioned in 16 requests. The surgery performed was mentioned in 15.94% requests. The number of containers varies from 1 to 5, with a median of 2. The containers include capsules in 242 cases, 161 as isolated capsule, 27 mammary tissue, and capsule in the same specimen, 54 mammary tissues sent in a separate container, anatomical and spatial location was mentioned in 6.33% cases. The detailed clinical data was included in 19.12%, signs and symptoms 13.94%, contracture as the only item mention in 64 of them. In 27 requests, lymphoma evaluation was requested. 15 included seroma and from nine of those, liquid was sent with a request for immunohistochemical and cytology analysis. None of the requests had any data on implant type or brand. Conclusion: The amount of information contained in the medical request forms is minimal. The authors recommend the need for a protocol to standardize the surgical removal of the capsule and the adjacent mammary tissue. Surgical specimens should be spatially oriented.

Abstract Background Clinically insignificant hemolytic anemia is occasionally a complication of prosthetic valve replacement. However, hemolysis related to kinked grafts is a very rare complication after central repair for acute aortic dissection. Case presentation A 42-year-old man had undergone replacement of the ascending aorta and a root repair for type A aortic dissection 6 months previously. Laboratory data showed mild hemolysis 5 months later, and he began to complain of fatigue on exertion. The serum hemoglobin level reduced to 8.6 g/dL, and lactate dehydrogenase levels increased to 3071 IU/L with gross change in urine color, indicating hemoglobinuria. We diagnosed mechanical hemolytic anemia caused by a kinked graft and planned a repeat operation. The kinked graft was resected and graft-graft anastomosis was performed. Postoperatively, the clinical course was uneventful, and the hemolytic anemia completely resolved. Conclusion We herein report a case of hemolytic anemia caused by kinking of the graft 6 months after acute aortic dissection repair. The diagnosis was swiftly made, and the patient was successfully managed with redo surgery.

Background: The use of prosthetic meshes in abdominal wall reconstruction is a well-established approach; however, in certain cases where a bowel resection coexists its application is disputed. Any underlying inflammatory process may augment adhesion formation which is a major postoperative complication. In this animal study, our aim was to investigate the effect of N-acetyl-l-cysteine (NAC) on adhesion formation and the expression of inflammatory markers when a mesh was used in a clean or a potentially contaminated environment. Methods: Sixty male Wistar rats were randomly and equally allocated in 3 groups: A, B and C. Animals in all groups underwent laparotomy, a prosthetic mesh was placed and chemoprophylaxis with ciprofloxacin was administered. In groups B and C an enterectomy was also performed. NAC was injected intraperitoneally in group C. Adhesion formation, IL-1a, IL-6, TNF-a and histological data including fibrosis, neutrophils’ infiltration and neovascularization were assessed. Mesh samples were sent for cultivation. Results: Adhesion formation was significantly less and inflammation markers were also lower in group C compared to group B (p

Calcaneum fractures are debilitating injuries with high complication rates and poor functional outcomes after both operative and non-operative management. The optimal management of such fractures is still highly debated in the literature with conflicting evidence on the preferred management of displaced intra-articular calcaneum fractures (DICAF). This article reviews the current concepts in the management of DIACF. [ABSTRACT FROM AUTHOR]

Perioperative frailty is prevalent and requires complex management, which could be guided by clinical practice guidelines (CPGs). The objective of this systematic review was to identify and synthesise CPGs that provide perioperative recommendations specific to older adults living with frailty. After protocol registration, we performed a systematic review of CPGs. MEDLINE, Embase, CINAHL, and 14 grey literature databases were searched (January 1, 2000 until December 22, 2021). We included all CPGs that contained at least one frailty-specific recommendation related to any phase of the perioperative period. We compiled all relevant recommendations, extracted underlying strength of evidence, and categorised them by perioperative phase of care. Within each phase, recommendations were synthesised inductively into themes. Quality of CPGs was assessed using the Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument. From 4707 citations, 13 guidelines were included; 8/13 were focused on the perioperative care of older surgical patients in general. Among 110 recommendations extracted, 37 themes were generated, with the majority pertaining to preoperative care. Four themes were supported by strong evidence: performing preoperative frailty assessments, using multidimensional frailty instruments, reducing urinary catheter use, and following multidisciplinary care and communication throughout the perioperative period. Per AGREE II, most guidelines (8/13; 62%) were recommended for use with modifications. Despite increasing numbers of patients living with frailty, few guidelines exist that address frailty-specific perioperative care. Given the lack of strong evidence-based recommendations, particularly outside the preoperative period, high-quality primary research is required to underpin future guidelines and better inform the care of older surgical patients with frailty.

ABSTRACT Background: classical models of microsurgical anastomosis training are expensive and have ethical implications. Some alternatives join low cost and easiness to store. However, the translation of knowledge acquired by training in these methods into the traditional ones is not clear. This project aims to assess the feasibility of konjac noodles as a reliable microsurgery-training model. Methods: 10 neurosurgery residents performed an end-to-end anastomosis in a 2-3mm placenta artery. The anastomoses were evaluated quantitatively, recording time; and qualitatively, applying a validated score (Anastomosis Lapse Index - ALI) by three experienced neurosurgeons and verifying the presence of gross leakage through the infusion of fluorescein. Subsequently, they performed 10 non-consecutive sessions of anastomosis training in the konjac noodle. Eventually, a final anastomosis in the placenta model was performed and the same parameters were scored. Results: we observed a 17min reduction in the mean time to perform the anastomosis in the placenta model after the training in the konjac (p
