Background: Hyponatremia is a common electrolyte imbalance in hospitalized patients, including those undergoing orthopedic surgery. It is associated with increased mortality and morbidity. Early symptoms of hyponatremia are often vague and can be mistaken for normal post-operative sequelae. Therefore, it is important to be aware of hyponatremia’s risk factors and symptoms in post-operative orthopedic patients, especially in older patients. Aims and Objectives: The aims and objectives are to study the incidence of post-operative hyponatremia in patients undergoing lower-limb orthopedic surgery. Materials and Methods: This prospective observational study was done on 140 elective and emergency lower-limb surgery patients. The patients were divided into two groups based on their age. Group A comprised 70 patients under 65, and Group B comprised 70 patients over 65. The patients underwent pre-operative assessments, including complete physical and systemic examinations and routine pre-operative workups, including checking serum sodium and potassium levels. Results: In a study of 140 post-operative orthopedic patients, 55 (39%) had low serum sodium levels on post-operative day 1. Of these, 46 had mild hyponatremia, 7 had moderate hyponatremia, and 2 had severe hyponatremia. Elderly patients were more likely to develop hyponatremia than younger patients (27% vs. 12%, P=0.003). The most common symptoms of hyponatremia were headache (8.6%), nausea (3.6%), lethargy (7.1%), confusion (6.4%), and disorientation (1.4%). Hyponatremic patients had longer hospital stays than normal patients (13 days vs. 5–11 days). Conclusion: The elderly population had a higher incidence of post-operative hyponatremia and was more vulnerable to developing symptoms. Although hyponatremia following surgery is common after orthopedic surgeries, it is primary, temporary, and easily treatable.

There are many causes of ST-elevation on electrocardiogram (ECG). ECG changes in the setting of intra-abdominal pathology is a rare and under characterised and includes the “spiked helmet sign”. We report a rare case of the “spiked helmet sign” that presented with ST-elevation in the precordial leads due to post-operative ileus.

Abstract Background The role of lactate level in selecting the timing of definitive surgery for isolated extremity fracture remains unclear. Therefore, we aimed to elucidate the use of preoperative lactate level for predicting early postoperative complications. Methods This was a single-center retrospective observational study of patients with isolated extremity fracture who underwent orthopedic surgery. Patients who underwent lactate level assessment within 24 h prior to surgery were included. The incidence of early postoperative complications was compared between patients with a preoperative lactate level of ≥ 2 and

Key Clinical Message: Afferent loop syndrome is a rare post‐operative complication following upper gastrointestinal bypass surgeries, usually occurring within the first two weeks post‐operation. This case report, however, outlines afferent loop syndrome almost a decade post‐surgery, which was managed conservatively. A 54‐year‐old woman presented with a few days' history of epigastric pain, vomiting, and constipation. She had undergone a sleeve gastrectomy and was converted to a Roux‐en‐Y gastrojejunostomy for weight loss 9 and 7 years ago, respectively. Serum lipase was elevated at 1410 IU/L. Computed tomography showed high‐grade proximal small bowel obstruction, involving the efferent and afferent loops of the Roux‐en‐Y gastric bypass. The patient was given intravenous rehydration, electrolyte replacement and had a nasogastric tube inserted. She was discharged on day 5 of admission without significant sequelae. Afferent limb syndrome should be considered in patients with altered upper gastrointestinal anatomy who present with pancreatitis, regardless of the time period post‐operatively. Future guidelines should further more outline the factors indicated for surgical versus conservative management. [ABSTRACT FROM AUTHOR]

Background: The role of lactate level in selecting the timing of definitive surgery for isolated extremity fracture remains unclear. Therefore, we aimed to elucidate the use of preoperative lactate level for predicting early postoperative complications. Methods: This was a single-center retrospective observational study of patients with isolated extremity fracture who underwent orthopedic surgery. Patients who underwent lactate level assessment within 24 h prior to surgery were included. The incidence of early postoperative complications was compared between patients with a preoperative lactate level of ≥ 2 and < 2 mmol/L. Moreover, subgroup analyses were performed based on the time from hospital arrival to surgery and fracture type. Results: In total, 187 patients were included in the study. The incidence of postoperative complications was significantly higher in patients with a preoperative lactate level of ≥ 2 mmol/L than those with a preoperative lactate level of < 2 mmol/L. This result did not change after adjusting for age and severity. Further, a high preoperative lactate level was associated with a greater incidence of postoperative complications in patients who underwent definitive surgery within 6 h after arrival. Conclusion: A preoperative lactate level of ≥ 2 mmol/L was associated with a greater incidence of early postoperative complications in isolated extremity fractures. Nevertheless, this correlation was only observed among patients who underwent definitive fixation within 6 h after hospital arrival. [ABSTRACT FROM AUTHOR]

Objective: We aimed to analyse the risk factors of complications after laparoscopic anterior resection of rectal cancer, and to establish a nomogram prediction model and evaluate its accuracy. Patients and Methods: We retrospectively analysed the clinical data of 180 patients undergoing laparoscopic anterior resection of rectal cancer. Univariate analysis and multivariate logistic regression analysis were used to screen the potential risk factors of post-operative complications of Grade II and establish a nomogram model. The receiver operating characteristic (ROC) curve and Hosmer-Lemeshow goodness-of-fit test were used to evaluate the discrimination and coincidence of the model, and the calibration curve was used to internally verify. Results: A total of 53 patients (29.4%) with rectal cancer had Grade II post-operative complications. Multivariate logistic regression analysis showed that age (odds ratio [OR] =1.085, P < 0.001), body mass index ≥24 kg/m2 (OR = 2. 763, P = 0. 008), tumour diameter ≥5 cm (OR = 3. 572, P = 0.002), tumour distance from anal margin ≤6 cm (OR = 2.729, P = 0.012) and operation time ≥180 min (OR = 2.243, P = 0.032) were independent risk factors for Grade II post-operative complications. The area under the ROC was 0.782 (95% confidence interval: 0.706-0.858, sensitivity: 66.0%, specificity: 76.4%) in the nomogram prediction model. Hosmer-Lemeshow goodness-of-fit test showed χ2 = 9.350, P = 0.314. Conclusion: Based on five independent risk factors, the nomogram prediction model has a good predictive performance for post-operative complications after laparoscopic anterior resection of rectal cancer, which is helpful to early identify high-risk people and formulate clinical intervention measures.

Background: Incidence of post-operative complications after sleeve gastrectomy (SG) is low. However, the early identification of these complications remains crucial. Here, we report the impact of routine laboratory monitoring for the early diagnosis of complications after SG. Material and Methods: From January 2018 to December 2019, all consecutive patients who underwent primary SG (n = 457) were included. This was a comparative study of patients undergoing primary SG. Patients were divided into two groups: one group with routine laboratory monitoring performed at postoperative day (POD) 1 and 3 (LAB group) and another group without routine laboratory monitoring (control group). The study's primary endpoint was the overall impact of routine laboratory monitoring. The secondary endpoints were evaluation of patients with complications. Results: The population in the two groups were similar in term of demographic and intra-operative data. There was a statistical difference between the two groups in term of length of stay (5.7 days in the LAB group and 3.5 days in the control group (p < 0.001)). There were 19 complications (6.0%) in the LAB group and 5 complications in the control group (3.5%) (p = 0.25). A cut-off C-reactive protein level of 46.3 mg/l was found to be significant (p = 0.006). In the LAB group, 9 patients (2.9%) required readmission vs. three patients (2.0%) in the control group (p = 0.62). Conclusion: The interest of routine laboratory monitoring after SG seems limited. Routine laboratory monitoring alone is not associated with earlier diagnosis of complications. This routine monitoring is associated with an increase of stay in hospital. [ABSTRACT FROM AUTHOR]

Introduction The multicenter CHAMPION study aimed to assess the impact of smoking cessation on post-operative complications (PCs) and smoking cessation patterns in Chinese patients undergoing lung surgery. Methods Patients undergoing elective lung surgery were prospectively enrolled from three major tertiary centers in China. Patients were categorized as smokers or quitters before surgery. Baseline characteristics and smoking status were analyzed. The incidence of PCs and pulmonary PCs (PPCs), smoking relapse rate, and causes within six months post-operatively were investigated. The questionnaire was conducted in all patients and 30 healthcare professionals (HCPs), regarding the awareness and effectiveness of smoking cessation methods. Results Of the 276 enrolled patients, 213 (77.2%) were smokers and 63 (22.8%) were quitters; 76.4% were diagnosed with primary lung cancer. PCs occurred in 13.8% of patients, with similar proportions in smokers (14.1%) and quitters (12.7%). PPCs occurred in 9.8% of patients with no significant differences between smokers and quitters (9.4% vs 11.1%, p=0.70). At six months, 9.2% of patients relapsed, with a lower rate in quitters compared to smokers (3.3% vs 11.0%, p=0.01). HCPs exhibited higher awareness of smoking cessation methods than patients. Perceived effectiveness of smoking cessation methods from the patients were low. Conclusions In patients undergoing lung surgery with a low risk of PCs, active smoking does not significantly increase the risk of PCs or PPCs relative to quitters, suggesting that there is likely no need to postpone lung surgery for those who have not yet quit smoking. However, further large-scale studies are necessary to confirm these findings.

BACKGROUND: Imposed immobilization after electrophysiological studies (EPS) is known to cause different complications. The current study aims to assess the effect of early ambulation on comfort and vascular complications among patients undergoing transfemoral catheterization for EPS. MATERIALS AND METHODS: Hundred participants were assigned to control and intervention groups (50 each) using block randomization. The control group participants were ambulated at 6 hours after EPS. For the intervention group, participants were kept in the supine position with procedure-side leg extension for the first 2 hours, followed by 30° head-end elevation and turning to the left/right side for 30 min, and finally ambulation at the end of 3 hours. Both groups were assessed for vital signs, groin and back pain, satisfaction, bleeding, hematoma, and bladder pattern at the 6th and 24th hour after EPS. Data analysis was done on an intention-to-treat basis using the Chi-square test, Fisher’s exact test, independent student t-test, and Mann–Whitney U test. RESULTS: The level of back pain and groin pain was significantly lower in intervention group after 6 hours (P < 0.001) and after 24 hours (P < 0.05). Urinary problem was not reported in intervention group, whereas Eleven (22%), participants in the control group did not void at 6 hours (P < 0.001). Two patients in intervention group developed bleeding at 6 hours, and one patient in control group developed bleeding at 24 hours. Hematoma development was absent for both groups. CONCLUSION: Early ambulation at 3 hours after EPS is suggested to reduce back pain, groin pain, and urinary problem, without risk for vascular complications.

Recently, there has been a rapid shift from open shoulder surgery to arthroscopic shoulder procedures for treating several shoulder pathologies. This shift is mainly due to reduced postoperative complications and 30-day readmission. Although the 30-day readmission rate is low, the risk still exists. One way to minimize the risk factors is to analyze all the risk factors contributing to the 30-day readmission following shoulder arthroscopy. Electronic databases such as PubMed, Google Scholar, and Cochrane library were searched. Studies were selected based on predefined inclusion and exclusion criteria. Newcastle–Ottawa score was used for the quality assessment of individual studies. Two reviewers extracted data from the selected studies. Results were evaluated through narrative analysis and presented as an odds ratio with 95% confidence interval. A meta-analysis was not possible due to the heterogeneity in the available data. A total of 12 studies evaluating 494,038 patients were selected in our review. All the studies have a low risk of bias (median = 8). Significant factors predicting readmission included age, gender, COPD (chronic obstructive pulmonary disorder), steroid use, smoking, preoperative opioid use, higher American Society of Anesthesiologists (ASA) score (3 or higher), and general and regional anesthesia vs. regional anesthesia alone. Through our systematic review, we tried to identify risk factors that can predict 30-day readmission following shoulder arthroscopy. These include age > 65 years, COPD, steroid use, opioid use, and OR time > 90 mins. These high-risk patients could be triaged earlier by identifying these parameters, and effective pre and post-operative surveillance could minimize 30-day readmission risk following shoulder arthroscopy.

Abstract Introduction Patients undergoing major cardiothoracic or abdominal surgery are at increased risk of developing post‐operative pulmonary complications (PPC), but respiratory physiotherapy can prevent PPC. We have previously developed the PPC Risk Prediction Score to allocate physiotherapists' resources and stratify patients into three risk groups. In this study, we performed a temporal external validation of the PPC Risk Prediction Score. Such validation is rare and adds to the originality of this study. Methods A cohort of 360 patients, admitted to undergo elective cardiothoracic or abdominal surgery, were included. Performance and clinical usefulness of the PPC Risk Prediction Score were estimated through discrimination, calibration and clinical usefulness, and the score was updated. Results The score showed c‐statistics of 0.62. Related to clinical usefulness, a cut point at 8 gave a sensitivity of 0.49 and a specificity of 0.70, whereas a cut point at 12 gave a sensitivity of 0.13 and a specificity of 0.95. Two predictors included in the development sample score, thoraco‐abdominal incision odds ratio (OR) 2.74 (1.12;6.71) and sternotomy OR 2.09 (1.18;3.72), were statistically significantly associated to PPC in the validation sample. Conclusions The score was not able to discriminate between patients with and without PPC; neither was the updated score, but the study identified clinically relevant risk factors for developing PPC.

Introduction: The incidence of post-operative urinary retention (POUR) following inguinal hernia repair (IHR) is approximately 0.4% - 22.0%. POUR may lead to patient discomfort and catheter-related complications including urinary tract infection, urethral trauma, bladder overdistension and subsequent permanent bladder dysfunction. We aimed to perform a systematic review and meta-analysis of randomised control trials (RCT) evaluating the impact of administration of perioperative alpha-blockade to reduce the incidence of acute POUR following IHR. Methods: A systematic review was performed as per PRISMA guidelines. The incidence of POUR in the alpha-blocker and control groups were expressed as dichotomous outcomes, reported as odds ratios (ORs) expressed with 95% confidence intervals (CIs) following estimation using the Mantel-Haenszel method. Results: Eight RCTs with a combined total of 918 patients were included. Of these, 53.7% (493/918) received alpha-blockers while 46.3% (425/918) did not. Five studies used tamsulosin, two used prazosin and one used phenoxybenzamine. Overall, the prescription of prophylactic alpha-blockers in the preoperative setting significantly reduced POUR compared to the control group (7.9% (39/493) vs 21.2% (90/425), OR: 0.31, 95% CI: 0.12–0.80, P = 0.020). Conclusion: Preoperative prescription of alpha-blockers reduced the incidence of POUR following inguinal hernia repair. The next generation of prospective randomised trials may identify which patients should be prescribed this medication prior to surgery.

Background: Hypertension is one of the most common comorbidities among patients undergoing surgery. However, few studies have focused on patients undergoing knee arthroplasty, and most of them had small sample sizes. This study aimed to analyze post-operative complications associated with hypertension in patients who underwent knee replacement surgery. Methods: Data from the 2019 National Inpatient Sample (NIS) database were used. Patients who underwent primary total knee arthroplasty (pTKA) and those who underwent aseptic revision total knee arthroplasty (rTKA) were analyzed separately. Propensity score matching was performed to reduce the effects of demographic factors and comorbidities other than hypertension on post-operative complications. A multinomial logistic regression that included all significantly different demographics and comorbidities was performed to verify the results and evaluate the odds ratios. Results: A total of 107,981 patients who underwent pTKA and 6571 who underwent rTKA owing to mechanical complications were identified in the 2019 NIS database. Compared with the non-hypertension group, patients with hypertension had a higher risk of developing acute renal failure and electrolyte disorders after TKA. Further analysis revealed that hyponatraemia and hypokalaemia were associated with hypertension. Conclusions: Hypertension was associated with the incidence of acute renal failure after TKA. It is important to identify patients with risk factors for acute renal failure (in addition to hypertension) and take careful measures to prevent acute renal failure in them. [ABSTRACT FROM AUTHOR]

BackgroundOutcomes after lung transplant (LTx) in children have slowly improved. Although atrial arrhythmia (AA) is a common and adverse complication following LTx among adults, there is limited data on pediatric recipients. We detail our pediatric single-center experience while providing further insights on occurrence and management of AA following LTx.MethodsA retrospective analysis of LTx recipients at a pediatric LTx program from 2014 to 2022 was performed. We investigated timing of occurrence and management of AA following LTx, and its effect on post-LTx outcome.ResultsThree out of nineteen (15%) pediatric LTx recipients developed AA. The timing of occurrence was 9–10 days following LTx. Those patients in the older age group (age >12 years old) were the only ones who developed AA. Developing AA did not have a negative effect on hospital stay duration or short-term mortality. All LTx recipients with AA were discharged home on therapy that was discontinued at 6 months for those who was on mono-therapy without recurrence of AA.ConclusionsAA is an early post-operative complication in older children and younger adults undergoing LTx at a pediatric center. Early recognition and aggressive management can mitigate any morbidity or mortality. Future investigations should explore factors that place this population at risk for AA in order to prevent this complication post-operatively.

The purpose of the present systematic review was to describe the diagnostic evaluation of rheumatoid arthritis in the cervical spine to provide a better understanding of the indications and options of surgical intervention. We performed a literature review of Pub-med, Embase, and Scopus database. Upon implementing specific inclusion and exclusion criteria, all eligible articles were identified. A total of 1878 patients with Rheumatoid Arthritis (RA) were evaluated for cervical spine involvement with plain radiographs. Atlantoaxial subluxation (AAS) ranged from 16.4 to 95.7% in plain radiographs while sub-axial subluxation ranged from 10 to 43.6% of cases. Anterior atlantodental interval (AADI) was found to between 2.5 mm and 4.61 mm in neutral and flexion position respectively, while Posterior Atlantodental Interval (PADI) was between 20.4 and 24.92 mm. 660 patients with RA had undergone an MRI. A pannus diagnosis ranged from 13.33 to 85.36% while spinal cord compression was reported in 0–13% of cases. When it comes to surgical outcomes, Atlanto-axial joint (AAJ) fusion success rates ranged from 45.16 to 100% of cases. Furthermore, the incidence of postoperative subluxation ranged from 0 to 77.7%. With regards to AADI it is evident that its value decreased in all studies. Furthermore, an improvement in Ranawat classification was variable between studies with a report improvement frequency by at least one class ranging from 0 to 54.5%. In conclusion, through careful radiographic and clinical evaluation, cervical spine involvement in patients with RA can be detected. Surgery is a valuable option for these patients and can lead to improvement in their symptoms. [ABSTRACT FROM AUTHOR]

Purpose: Post-operative paralytic ileus (POI) occurs after surgery because of gastrointestinal dysfunction caused by surgical invasion. We therefore investigated the frequency of POI after laparoscopic colorectal surgery in patients with colorectal cancer using a strictly defined POI diagnosis and identified associated risk factors. Methods: Patients who underwent initial laparoscopic surgery for colorectal cancer between January 2014 and December 2018 were included. The primary end point was the incidence of POI. A multivariate logistic regression analysis revealed the contributing risk factors for POI. Results: Of the 436 patients, 94 (21.6%) had POI. Compared with the non-POI group, the POI group had significantly higher frequencies of infectious complications (p < 0.001), pneumonia (p < 0.001), intra-abdominal abscess (p = 0.012), anastomotic leakage (p = 0.016), and post-operative bleeding (p = 0.001). In the multivariate analysis, the right colon (odds ratio [OR] 2.180, p = 0.005), pre-operative chemotherapy (OR 2.530, p = 0.047), pre-operative antithrombotic drug (OR 2.210, p = 0.032), and post-operative complications of CD grade ≥ 3 (OR 12.90, p < 0.001) were independent risk factors for POI. Conclusion: Post-operative management considering the risk of post-operative bowel palsy may be necessary for patients with right colon, pre-operative chemotherapy, pre-operative antithrombotic drug or severe post-operative complications.

Introduction: Recent studies showed that balanced opioid-free anesthesia is feasible and desirable in several surgical settings. However, in thoracic surgery, scientific evidence is still lacking. Thus, we conducted the first systematic review and meta-analysis of opioid-free anesthesia in this field. Methods: The primary outcome was the occurrence of any complication. Secondary outcomes were the length of hospital stay, recovery room length of stay, postoperative pain at 24 and 48 h, and morphine equivalent consumption at 48 h. Results: Out of 375 potentially relevant articles, 6 studies (1 randomized controlled trial and 5 observational cohort studies) counting a total of 904 patients were included. Opioid-free anesthesia compared to opioid-based anesthesia, was associated with a lower rate of any complication (74 of 175 [42%] vs. 200 of 294 [68%]; RR = 0.76; 95% CI, 0.65–0.89; p < 0.001; I2 = 0%), lower 48 h morphine equivalent consumption (MD −14.5 [−29.17/−0.22]; p = 0.05; I2 = 95%) and lower pain at 48 h (MD −1.95 [−3.6/0.3]; p = 0.02, I = 98%). Conclusions: Opioid-free anesthesia in thoracic surgery is associated with lower postoperative complications, and less opioid demand with better postoperative analgesia at 48 h compared to opioid-based anesthesia.

Objectives: COVID-19 predominately affects safety net hospitals. Tracheostomies improve outcomes and decrease length of stay for COVID-19 patients. Our objectives are to determine if (1) COVID-19 tracheostomies have similar complication and mortality rates as non-COVID-19 tracheostomies and (2) to determine the effectiveness of our tracheostomy protocol at a safety net hospital. Methods: Patients who underwent tracheostomy at Los Angeles County Hospital between August 2009 and August 2020 were included. Demographics, SARS-CoV-2 status, body mass index (BMI), Charlson Co-morbidity Index (CCI), length of intubation, complication rates, decannulation rates, and 30-day all-cause mortality versus tracheostomy related mortality rates were all collected. Results: Thirty-eight patients with COVID-19 and 130 non-COVID-19 patients underwent tracheostomies. Both groups were predominately male with similar BMI and CCI, though the COVID-19 patients were more likely to be Hispanic and intubated for a longer time (P =.034 and P <.0001, respectively). Both groups also had similar, low intraoperative complications at 2% to 3% and comparable long-term post-operative complications. However, COVID-19 patients had more perioperative complications within 7 days of surgery (P <.01). Specifically, they were more likely to have perioperative bleeding at their tracheostomy sites (P =.03) and long-term post-operative mucus plugging (P <.01). However, both groups had similar 30-day mortality rates. There were no incidences of COVID-19 transmission to healthcare workers. Conclusions: COVID-19 tracheostomies are safe for patients and healthcare workers. Careful attention should be paid to suctioning to prevent mucus plugging.

The aim of this study was to investigate the effect of drains used in current clinical practice on operation parameters and post-operative morbidity. The comprehensive data obtained through the prospective design were analysed in detail according to whether abdominal drainage was applied. Abdominal drainage was present in 44.1% of patients who met the inclusion criteria. Drains were placed significantly more frequently during oncologic surgery (p =.007). The mean mobilisation (p =.001), first flatus (p =.001), and first oral intake (p =.029) times were longer in the drain group than those in the non-drain group. In patients who underwent oncological surgeries, no significant differences were observed except for the pre-operative duration of bowel preparation (p =.006) and first flatus time (p =.003). Our results suggest that drain placement in gynecological procedures does not provide an additional advantage. What is already known on this subject? Post-operative drainage of the abdominal cavity has been controversial for many years. However, whether abdominal drainage provides an additional benefit in lower and upper abdominal surgical procedures remains unclear. What do the results of this study add? Most studies have examined post-operative pain and surgical site infections. We examined the relationship between abdominal drainage and demographic and pre-/post-operative clinical features in detail. We demonstrated that abdominal drainage in gynecological procedures may not provide an additional advantage. What are the implications of these findings for clinical practice and/or further research? The present study provides valuable information that can guide physicians in deciding whether to use post-operative abdominal drainage. This topic warrants investigation with randomised data in the future. [ABSTRACT FROM AUTHOR]

No abstract available. Article truncated after the first 150 words. History of Present Illness: An 82-year-old man presented to his physician for general health maintenance as well as a complaint of persistently poor quality sleep and poor appetite with weight loss. The patient had undergone robotic-assisted radical left nephroureterectomy and cystectomy with pelvic lymph node dissection and urinary diversion for left clear cell renal cell carcinoma (staged T2a, grade 2) and transitional cell carcinoma of the bladder (carcinoma in situ at surgery), approximately 9 months earlier. The patient’s bladder malignancy was initially treated with transurethral resection, with histopathology at that procedure showing high-grade papillary urothelial malignancy with lamina propria invasion, but no muscular invasion; this procedure was followed by formal complete resection approximately 3 months later. The patient’s post-operative course was complicated by significant bleeding which required transfusion of 3 units of blood. He had undergone inferior vena caval filter placement prior to surgery when preoperative testing revealed lower extremity …

Persistent gastrocutaneous fistula (GCF) is a common complication after removal of a gastrostomy tube. Many different techniques for GCF closure have been described. A novel technique involving a punch biopsy device was recently described, called the Punch Excision of Epithelialized Tract (PEET) procedure. This case report describes a serious complication of necrotizing soft tissue infection after utilizing the PEET procedure for a GCF closure.

Background: The aim of our prospective multicentre study is to evaluate the five-year follow-up outcomes of primary reverse shoulder replacement utilizing two different designs of glenoid baseplates. Methods: There were 159 reverse shoulder replacements (91 cemented and 68 uncemented stems, 67 Trabecular Metal baseplates and 92 Anatomical Shoulder baseplates in 152 patients (99 women) with a mean age of 74.5 (58–90) years. The principal diagnosis was rotator cuff arthropathy in 108 shoulders. Results: Clinical and functional results improved significantly overall; the adjusted Constant Murley score improved from 28.2 ± 13.3 pre-operatively to 75.5 ± 22.8 (p < 0.0001) and the mean Subjective Shoulder Value improved from 27.5 ± 20 to 73.8 ± 21.3 points (p < 0.0001). Radiologically, there was good bony stability in 88% and 86% of cemented and uncemented stems without significant impact on the Constant Murley score and Subjective Shoulder Value at one, two and five years post-surgery. There were no significant clinical differences between Trabecular Metal and Anatomical Shoulder baseplates at five years. There were four cases of intraoperative shaft fractures that were managed with cables. Although the Trabecular Metal baseplates showed better integration radiologically, there was no significant difference in the mean of Constant Murley, Subjective Shoulder Value and the range of motion depending on the grade of inferior scapular notching at one-, two- and five-year intervals. Conclusions: Reverse total shoulder arthroplasty restores the function in shoulder with significant improvements in function and moderate complications with minor differences between both designs of baseplates that were not reflected clinically.

Analysing morbidity and using this to improve the quality of patient care is an important component of clinical governance. Several methods of data collection and clinical analysis have been suggested, but to date none have been widely adopted. All adult patients sustaining facial fractures were prospectively identified between 01 March 2019 and 28 February 2020, and matched to those who required a return to theatre for surgical complications. Morbidity resulting in a return to theatre was determined using the Clavien-Dindo classification and the Northwestern University error ascribing method. During this period, return to theatre occurred for 33/285 (11.6%) procedures and 23/173 (13.3%) of patients being treated for facial fractures. According to the 27 procedures discussed, Clavien-Dindo Grade IIIb was most commonly found (20/27). Error in judgement (13/35) and nature of disease (12/35) were ascribed as the most common causes of error. Presence of a consultant was associated with increased odds of a return to theatre (p = 0.014). Standardised national data collection of morbidity and error is required for comparisons of outcomes within a single institution or between institutions. To the best of our knowledge, this is the first paper to utilise these widely used methods of morbidity analysis for facial fracture surgery. We would recommend further development of an error analysis method that is more specific to complications from facial fracture surgery. [ABSTRACT FROM AUTHOR]

Purpose: The goal of this study was to evaluate, using definitive diagnostic criteria, the incidence of lymphocyst formation following pelvic lymphadenectomy for gynecological cancer, and to compare rates between the approaches of laparoscopy and laparotomy. Methods: We retrospectively reviewed the medical records of all patients who underwent pelvic lymphadenectomy for cervical or endometrial cancer between March of 2010 and March of 2016. We defined a lymphocyst as a circumscribed collection of fluid within the pelvic cavity, with a diameter of 2 cm or more, as diagnosed with ultrasound or computed tomography. Results: During the six-year observational period, a pelvic lymphadenectomy was conducted in 196 women with clinical stage I uterine cancer; 90 cases underwent laparoscopy, 106 underwent laparotomy. The minimally invasive laparoscopic group had a lower estimated blood loss (p < 0.01), shorter hospital stay (p < 0.01). Lymphocysts were observed in 14.4% (13/90) of the laparoscopy cases, and in 15.1% (16/106) of the laparotomy cases which means no significant difference of lymphocyst (p = 1.00). The median size of symptomatic lymphocyst was significantly larger in laparotomy group than in laparoscopy group (4.8 cm v.s. 2.8 cm, median) (p = 0.04). Symptomatic lymphocysts were more common in laparotomy [7/90 (7.8%) vs 14/106 (13.2%) (p = 0.253)]. Conclusions: In a retrospective analysis with a strict diagnostic criteria, we could find no statistical difference in lymphocyst occurrence between laparoscopy and laparotomy. The median size of the lymphocyst was bigger and lymphocyst was likely to be symptomatic in the laparotomy group. [ABSTRACT FROM AUTHOR]

Abstract Background Gluteal compartment syndrome is an uncommon condition and can be difficult to diagnose. It has been diagnosed after trauma, vascular injury, infection, surgical positioning, and prolonged immobilization from drug or alcohol intoxication. The diagnosis is based on clinical findings and, in most cases, recognizing these symptoms and making a diagnosis early is critical to a complete recovery. Case presentation A 53-year-old male who underwent left foot surgery had severe pain to his contralateral hip and posterior gluteal compartment radiating to the right lower extremity immediately postoperative. He was positioned supine with a “bump” placed under his right hip to externally rotate his operative leg during the surgery. Due to the patient’s complex past medical history, a presumptive diagnosis of a herniated disc and/or compression of the sciatic nerve was made as a cause for the patient’s pain. This resulted in a misdiagnosis period of 36 h until the patient was diagnosed with unilateral gluteal compartment syndrome. Performing a fasciotomy was decided against due to the increased risk of complications. The patient was treated with administration of IV fluids and closely monitored. On post-op day 6, the patient was discharged. At three months post-op, the patient was walking without a limp and he had no changes in his peripheral neurologic examination compared to his preoperative baseline. Conclusion Gluteal compartment syndrome is a surgical emergency that must be considered postoperatively especially in obese patients with prolonged operation times who experience acute buttock pain. The use of positional bars or “bumps” in the gluteal area should be used with caution and raise awareness of this complication after orthopedic surgeries.

Mycotic aneurysms are localized and irreversible dilatations of the arteries caused by weakening and damaging the arterial wall by an invasive organism establishing infective arteritis. Mycotic aneurysm of the thoracic aorta is a rare event; however, it can be fatal if not diagnosed early or not treated appropriately. Clinical findings are usually nonspecific; however, contrast-enhanced computed tomography (CT) is a common imaging modality of choice for the detection of mycotic aneurysms. Current management consists of antibiotic therapy and surgical treatment or endovascular interventions as early as possible. Herein, we present a case report of mycotic aneurysm of the thoracic aorta as a postoperative complication in a 60-year-old female with a clinical history of the cardia and esophageal carcinoma who underwent thoracic surgery. The presence of mycotic aneurysm was detected after performing a contrast-enhanced thoracic CT scan

Background: Imposed immobilization after electrophysiological studies (EPS) is known to cause different complications. The current study aims to assess the effect of early ambulation on comfort and vascular complications among patients undergoing transfemoral catheterization for EPS., Materials and Methods: Hundred participants were assigned to control and intervention groups (50 each) using block randomization. The control group participants were ambulated at 6 hours after EPS. For the intervention group, participants were kept in the supine position with procedure-side leg extension for the first 2 hours, followed by 30° head-end elevation and turning to the left/right side for 30 min, and finally ambulation at the end of 3 hours. Both groups were assessed for vital signs, groin and back pain, satisfaction, bleeding, hematoma, and bladder pattern at the 6 th and 24 th hour after EPS. Data analysis was done on an intention-to-treat basis using the Chi-square test, Fisher's exact test, independent student t -test, and Mann-Whitney U test., Results: The level of back pain and groin pain was significantly lower in intervention group after 6 hours ( P < 0.001) and after 24 hours ( P < 0.05). Urinary problem was not reported in intervention group, whereas Eleven (22%), participants in the control group did not void at 6 hours ( P < 0.001). Two patients in intervention group developed bleeding at 6 hours, and one patient in control group developed bleeding at 24 hours. Hematoma development was absent for both groups., Conclusion: Early ambulation at 3 hours after EPS is suggested to reduce back pain, groin pain, and urinary problem, without risk for vascular complications., Competing Interests: There are no conflicts of interest., (Copyright: © 2024 Journal of Education and Health Promotion.)

Introduction: A popliteal cyst, or Baker's cyst, is often associated with joint diseases such as osteoarthritis and rheumatoid arthritis (RA). It is rare for these cysts to develop following total knee arthroplasty (TKA), but understanding when and why they might can optimize patient care. Presented here is a unique case of a massive, chronically recurring infected popliteal cyst in a patient with RA and prior TKA, shedding light on an unusual complication worth attention in the orthopedic literature., Case Report: In this case, the patient had longstanding, difficult-to-treat RA. Following left TKA, the patient developed a painful popliteal cyst, leading to hospitalization in 2023. Microbiological analysis identified Staphylococcus lugdunensis as the infectious agent despite negative mycobacterial and mycological cultures. Surgical intervention involved a one-stage procedure, encompassing resection of the extensive thigh cyst and prosthesis replacement. Notably, the cyst reached an unprecedented size, measuring 32 cm at its peak, presenting a unique challenge in management., Conclusion: This case report contributes significantly to orthopedic literature by highlighting the intricate interplay between joint pathologies, surgical interventions, and infections. It highlights the importance of multidisciplinary collaboration in managing complex musculoskeletal conditions. The rarity of a massive and infected popliteal cyst post-TKA emphasizes the need for heightened vigilance in patient care post-surgery. Furthermore, this case report serves as a valuable addition to the understanding of potential complications associated with TKA, offering insights that may inform future treatment strategies and optimize patient outcomes in orthopedic practice., Competing Interests: Conflict of Interest: Nil, (Copyright: © Indian Orthopaedic Research Group.)

Introduction: Ankle fractures associated with disruption of the syndesmotic complex could potentially have poorer outcomes if missed or malreduced at the time of surgery. Favourable results have been reported for the suture button (SB) technique and may provide advantages over standard screw fixation of the syndesmosis, although this remains the gold standard method in many units., Aim: To compare the outcomes of syndesmotic screws (SS) with SB fixation of the syndesmosis during ankle fracture fixation at a high-volume orthopaedic department of a Scotland trauma unit., Method:  A cross-sectional, retrospective study looking at ankle fracture fixations was undertaken at the Clyde Trauma Unit, Paisley. Relevant information was obtained from electronic patient records for 457 ankle fracture patients between August 2019 and February 2022 and followed up for six months. The digital patient archive system (PACS) was used for evaluating radiographs. Patients were divided into two groups depending on whether they had an SS or SB fixation of their syndesmosis. We focused on the surgical and radiological outcomes following syndesmotic fixation as no functional scores following surgery were conducted on the patients., Result: Out of the entire study group, 26.3% (120/457 patients) required syndesmotic fixation. Within the syndesmotic fixation group, 70.8% (85/120 patients) underwent SS fixation, and 29.2% (35/120 patients) had an SB fixation. Both groups were statistically well-matched. Additionally, 21.1% (18/85) of SS fixation went on to have a second surgical procedure (four fixation failures, five planned removals, five for pain/stiffness, two infections, and two metalwork breakage/migration), whereas 8.6% (3/35) of the SB fixation group had a secondary procedure - two for fixation failures and one for infection., Conclusion: We reported a higher incidence of associated syndesmotic injury in our series of 457 ankle fractures than previously described. There were significantly fewer sequelae in the SB group compared to the SS fixation group (P = 0.0464). Although we did not observe a statistically significant difference in the rate of reoperation (P = 0.1184), this is likely due to the small numbers in the SB group. Our study suggests that SB fixation may be associated with a lower rate of reoperation for post-op complications such as metalwork failure, pain, and stiffness (21.1% SS vs 8.6% SB). Regardless of the fixation method used, accurate reduction of the ankle mortice and syndesmosis is a key step to a successful surgical outcome., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Objective: This study aimed to evaluate in hospital outcomes after carotid endarterectomy (CEA) according to shunt usage, particularly in patients with contralateral carotid occlusion (CCO) or recent stroke. Data from CEAs registered in the Vascular Quality Initiative database between 2012 and 2020 were analysed, excluding surgeons with < 10 CEAs registered in the database, concomitant procedures, re-interventions, and incomplete data., Methods: Based on their rate of shunt use, participating surgeons were divided in three groups: non-shunters (< 5%), selective shunters (5 - 95%), and routine shunters (> 95%). Primary outcomes of in hospital stroke, death, and stroke and death rate (SDR) were analysed in symptomatic and asymptomatic patients., Results: A total of 113 202 patients met the study criteria, of whom 31 147 were symptomatic and 82 055 were asymptomatic. Of the 1 645 surgeons included, 12.1% were non-shunters, 63.6% were selective shunters, and 24.3% were routine shunters, with 10 557, 71 160, and 31 579 procedures in each group, respectively. In the univariable analysis, in hospital stroke (2.0% vs. 1.9% vs. 1.6%; p = .17), death (0.5% vs. 0.4% vs. 0.4%; p = .71), and SDR (2.2% vs. 2.1% vs. 1.8%; p = .23) were not statistically significantly different among the three groups in the symptomatic cohort. The asymptomatic cohort also did not show a statistically significant difference for in hospital stroke (0.9% vs. 1.0% vs. 0.9%; p = .55), death (0.2% vs. 0.2% vs. 0.2%; p = .64), and SDR (1.0% vs. 1.1% vs. 1.0%; p = .43). The multivariable model did not show a statistically significant difference for the primary outcomes between the three shunting cohorts. On subgroup analysis, the SDRs were not statistically significantly different for patients with CCO (3.3% vs. 2.5% vs. 2.4%; p = .64) and those presenting with a recent stroke (2.9% vs. 3.4% vs. 3.1%; p = .60)., Conclusion: No statistically significant differences were found between three shunting strategies for in hospital SDR, including in patients with CCO or recent stroke., (Copyright © 2024 The Author(s).

Gluteal augmentation surgery, commonly known as the Brazilian Butt Lift (BBL), has become increasingly popular and is offered at numerous surgical centers. Typically performed on an outpatient basis, the procedure takes less than four hours, making it an appealing option for many patients. However, BBL is associated with multiple complications, some of which can be severe, resulting in high mortality rates. Most such post-operative adverse events necessitate urgent transfer to hospitals for optimal care, with post-operative respiratory distress being one such critical sign. Fat embolism syndrome (FES) is a notable complication of BBL. The diagnosis of FES is primarily clinical, supported by imaging studies such as chest X-rays and CT scans. FES often goes underdiagnosed due to the lack of definitive diagnostic criteria and its clinical and radiological similarities to other conditions. Despite its underdiagnosis, FES is reported in approximately 0.06% of patients undergoing BBL. Failure to diagnose it early can lead to complications from empiric treatment of other suspected conditions, potentially worsening the prognosis. Our patient developed respiratory failure within an hour after undergoing BBL. The time to symptom onset and the patient's agitation before the respiratory episode broadened the differential for her condition. This case report highlights the importance of recognizing FES and exploring potential preventive measures, including advancements in surgical techniques and prophylactic strategies., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Background: We sought to assess the efficacy of prophylactic abdominal drainage to prevent complications after appendectomy for perforated appendicitis. Methods: In this post hoc analysis of a prospective multi-center study of appendicitis in adults (≥ 18 years), we included patients with perforated appendicitis diagnosed intra-operatively. The 634 subjects were divided into groups on the basis of receipt of prophylactic drains. The demographics and outcomes analyzed were surgical site infection (SSI), intra-abdominal abscess (IAA), Clavien-Dindo complications, secondary interventions, and hospital length of stay (LOS). Multivariable logistic regression for the cumulative 30-day incidence of IAA was performed controlling for age, Charlson Comorbidity Index (CCI), antibiotic duration, presence of drains, and Operative American Association for the Surgery of Trauma (AAST) Grade. Results: In comparing the Drain (n = 159) versus No-Drain (n = 475) groups, there was no difference in the frequency of male gender (61% versus 55%; p = 0.168), weight (87.9 ± 27.9 versus 83.8 ± 23.4 kg; p = 0.071), Alvarado score (7 [6-8] versus 7 [6-8]; p = 0.591), white blood cell (WBC) count (14.8 ± 4.8 versus 14.9 ± 4.5; p = 0.867), or CCI (1 [0-3] versus 1 [0-2]; p = 0.113). The Drain group was significantly older (51 ± 16 versus 48 ± 17 years; p = 0.017). Drain use increased as AAST EGS Appendicitis Operative Severity Grade increased: Grade 3 (62/311; 20%), Grade 4 (46/168; 27%), and Grade 5 (51/155; 33%); p = 0.007. For index hospitalization, the Drain group had a higher complication rate (43% versus 28%; p = 0.001) and longer LOS (4 [3-7] versus 3 [1-5] days; p < 0.001). We could not detect a difference between the groups in the incidence of SSI, IAA, or secondary interventions. There was no difference in 30-day emergency department visits, re-admissions, or secondary interventions. Multi-variable logistic regression showed that only AAST Grade (odds ratio 2.7; 95% confidence interval7 1.5-4.7; p = 0.001) was predictive of the cumulative 30-day incidence of IAA. Conclusions: Prophylactic drainage after appendectomy for perforated appendicitis in adults is not associated with fewer intra-abdominal abscesses but is associated with longer hospital LOS. Increasing AAST EGS Appendicitis Operative Grade is a strong predictor of intra-abdominal abscess. [ABSTRACT FROM AUTHOR]

Limb graft occlusion (LGO) is a serious complication after endovascular aneurysm repair (EVAR) and while device development enables treatment of increasingly complex aortic anatomy, little is known about how endograft type affects the risk of occlusion. This observational study aimed to explore the incidence of LGO after EVAR for three major endograft systems. All patients with standard EVAR as the primary intervention for infrarenal abdominal aortic aneurysm (AAA), between January 2012 and December 2018, at five Swedish vascular surgery centres, were included in this multicentre retrospective cohort study. LGO was defined as a total limb occlusion regardless of symptoms, or a treated significant stenosis. A nested case control (NCC) design with incidence density sampling of 1:3 was used for analysis of potential per-operative and morphological risk factors. Conditional logistic regression was used to estimate multivariable odds ratios (OR) with 95% confidence intervals (CI) A total of 924 patients were included. The majority were male (84%), the mean age was 76 years (± 7.5 SD), and median AAA diameter was 59 mm (IQR 55, 67). Patients were treated with Zenith Alpha (n = 315, ZISL limbs), Excluder (n = 152, PLC/PXC limbs), and Endurant (n = 457, ETLW/ ETEW limbs). During median follow up of 37 months (IQR 21, 62), 55 occlusions occurred (5.9%); 39 with Zenith Alpha (12.4%), one with Excluder (0.7%), and 15 with Endurant (3.3%). In the NCC analysis, the Zenith Alpha device (OR 5.31, 95% CI 1.97 – 14.3), external iliac artery (EIA) landing (OR 5.91, 95% CI 1.30 – 26.7), and EIA diameter < 10 mm (OR 4.99, 95% CI 1.46 – 16.9) were associated with an increased risk of LGO. Endograft device type is an independent risk factor for LGO after EVAR. Specifically, the Zenith Alpha demonstrated an increased risk of LGO compared with the Endurant and Excluder devices. In addition, a narrow EIA and landing zone in EIA are also risk factors for LGO. [ABSTRACT FROM AUTHOR]

The decision to undertake a major lower limb amputation can be complex. This review evaluates the performance of risk prediction tools in estimating mortality, morbidity, and other outcomes following amputation. A systematic review was performed following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The MEDLINE, Embase, and Cochrane databases were searched to identify studies reporting on risk prediction tools that predict outcomes following amputation. Outcome measures included the accuracy of the risk tool in predicting a range of post-operative complications, including mortality (both short and long term), peri-operative morbidity, need for re-amputation, and ambulation success. A narrative synthesis was performed in accordance with the Guidance on the Conduct of Narrative Synthesis In Systematic Reviews. The search identified 518 database records. Twelve observational studies, evaluating 13 risk prediction tools in a total cohort of 61 099 amputations, were included. One study performed external validation of an existing risk prediction tool, while all other studies developed novel tools or modified pre-existing generic calculators. Two studies conducted external validation of the novel/modified tools. Nine tools provided risk estimations for mortality, two tools provided predictions for post-operative morbidity, two for likelihood of ambulation, and one for re-amputation to the same or higher level. Most mortality prediction tools demonstrated acceptable discrimination performance with C statistic values ranging from 0.65 to 0.81. Tools estimating the risk of post-operative complications (0.65 – 0.74) and necessity for re-amputation (0.72) also performed acceptably. The Blatchford Allman Russell tool demonstrated outstanding discrimination for predicting functional mobility outcomes post-amputation (0.94). Overall, most studies were at high risk of bias with poor external validity. This review identified several risk prediction tools that demonstrate acceptable to outstanding discrimination for objectively predicting an array of important post-operative outcomes. However, the methodological quality of some studies was poor, external validation studies are generally lacking, and there are no tools predicting other important outcomes, especially quality of life.

Background: The post-operative management of simple (acute) appendicitis differs throughout the United States. Guidelines regarding post-operative antibiotic usage remain unclear, and treatment generally is dictated by surgeon preference. We hypothesize that post-operative antibiotic use for simple appendicitis is not associated with lower post-operative complication rates. Methods: In a post-hoc analysis in a large multi-center observational study, only patients with an intra-operative diagnosis of AAST EGS Grade I were included. Subjects were classified into those receiving post-operative antibiotics (POST) and those given pre-operative antibiotics only (NONE). Clinical outcomes examined were length of stay (LOS), 30-day emergency department (ED) visits and hospital re-admissions, secondary interventions, surgical site infection (SSI), and intra-abdominal abscess (IAA). Results: A total of 2,191 subjects were included, of whom 612 (28%) received post-operative antibiotics. Compared with the NONE group, POST patients were older (age 37 [range 26-50] versus 33 [26-46] years; p < 0.001), weighed more (82 [70-96] versus 79 [68-93] kg (p = 0.038), and had higher white blood cell counts (13.5 ± 4.2 versus 13.1 ± 4.4/103/mcL (p = 0.046), Alvarado Scores (6 [5-7] versus 6 [5-7]; p < 0.001), and Charlson Comorbidity Indices (median score 0 in both cohorts; p < 0.001). The POST patients had a longer LOS (1 [1-2] versus 1 [1-1] days; p < 0.001). There were no differences in the number who had ED visits within 30 days (9% versus 8%; p = 0.435), hospital re-admission (4% versus 2%; p = 0.165), an index hospitalization SSI (0.2% for both cohorts; p = 0.69), an SSI within 30 days (4% versus 2%; p = 0.165), index hospitalization IAA rate (0.3% versus 0.1%; p = 0.190), 30-day IAA (2% versus 1%; p = 0.71), index hospitalization interventions (0.5% versus 0.1%; p = 0.137) or 30-day secondary interventions (2% versus 1%; p = 0.155). Conclusions: Post-operative antibiotic use after appendectomy for simple appendicitis is not associated with better post-operative clinical outcomes at index hospitalization or at 30 days after discharge.

Lymphoceles are lymphatic fluid collections resulting from lymphatic vessel disruption after surgery or trauma. They are most often described following retroperitoneal surgeries such as cystectomies, prostatectomies, renal transplants, and gynecologic surgeries. Most lymphoceles are asymptomatic and resolve spontaneously without treatment. If persistent, they can become infected or exert mass effect on adjacent structures causing pain, urinary, or lower limb edema particularly for lymphoceles in the pelvis Symptomatic lymphoceles should be treated to relieve symptoms and prevent functional compromise of vital adjacent structures. Although surgery has been traditionally accepted as the gold standard treatment, advances in imaging and interventional technology allow for less invasive, percutaneous treatment. Available minimally invasive treatment options include percutaneous aspiration, catheter drainage, sclerotherapy, and lymphangiography with lymphatic embolization. A review of these treatment options and a suggested algorithm for managing lymphoceles is presented. [ABSTRACT FROM AUTHOR]

Background: We examined the safety of laparoscopic surgery for colorectal cancer (CRC) in patients with pulmonary dysfunction, and evaluated risk factors (RF) for post‐operative complications. Methods: We defined pulmonary dysfunction as having any diagnosed pulmonary disease with spirometry findings of obstructive or restrictive defects. Clinicopathological factors of 213 patients with pulmonary dysfunction who underwent laparoscopic surgery for CRC at Toranomon Hospital from 1999 to 2016 were evaluated to retrospectively identify RFs for any post‐operative complications and major complications, namely post‐operative pulmonary complications (PPCs). Examined preoperative factors included age, gender, body mass index, tumour location, smoking history, percentage vital capacity (%VC), forced expiratory volume in 1 s (FEV1.0), a ratio of FEV1.0 to forced vital capacity and American Society of Anesthesiologists physical status grade. Intraoperative factors, such as operative time, blood loss and blood transfusion, were also assessed. Results: Forty patients (18.8%) developed any complications including PPCs. Multivariate analysis revealed that male, rectal cancer and spirometry findings (both low FEV1.0 (0.8 L) and low %VC (<95)) were RFs (P = 0.026, 0.003 and 0.007, respectively). Six cases (2.8%) developed PPCs. The prevalence of PPCs was higher in patients with both low %VC (<95%) and low FEV1.0 (<0.8 L), with statistical significance (P = 0.006). Conclusion: Our study suggested that not only low FEV1.0 but also low %VC was an important RF for post‐operative complications after laparoscopic surgery for CRC. [ABSTRACT FROM AUTHOR]

Introduction: Stoma closure surgery (SCS; restoring intestinal continuity) in children is associated with high post-surgical complication rates with no established preventive strategies. Although many of these complications can be directly or indirectly attributable to bowel obstruction, no anatomical obstructive pathology is found in the majority. Intestinal dysmotility in children with no prior surgery is a well-known entity, which can lead to clinical features similar to anatomical obstruction. It is not known if a similar pathology could be the reason for SCS complications as well. Method & Results: We retrospectively reviewed five consecutive cases in our institution between 2016 and 2018, where scintigraphy was utilized to assess bowel motility prior to SCS. The radiotracer is administered via stoma or per anum, admixed with barium for anatomical assessment. Three children had failed prior attempts at SCS (underlying disease: spontaneous neonatal perforation, necrotizing enterocolitis, colonic atresia). A fourth patient, with gastroschisis, had ongoing obstruction despite multiple stricture resections. In all these patients, a dysmotile section of bowel was identified on scintigraphy in the distal small or large bowel and was resected. Three had excellent post-surgical follow up with no complications; one patient died in the immediate postoperative period likely from unrelated cause. A fifth child had a normal bowel motility study prior to SCS and had an uneventful follow up. Conclusions: Areas of segmental dysmotility in the distal gut may be the primary cause of post-SCS complications. Using a novel approach of assessing bowel motility using scintigraphy, such areas can be identified pre-operatively and resected, leading to reduced post-SCS complications. We recommend further investigation and validation in a larger prospective study.

Sugammadex can rapidly reverse neuromuscular blockade and has several advantages over cholinesterase inhibitors. It is unclear, however, whether administration of sugammadex in the absence of intraoperative deep neuromuscular blockade has direct clinical benefits. The present study retrospectively assessed the ability of sugammadex to prevent post-operative respiratory adverse events in patients undergoing laparoscopic colorectal surgery in the absence of routine deep neuromuscular blockade. The medical records of patients who underwent laparoscopic colorectal surgery from 2014 to 2018 in a tertiary care hospital were reviewed. Patients who underwent reversal of neuromuscular blockade with sugammadex or pyridostigmine were subjected to propensity score matching. To assess their relative effects on post-operative adverse respiratory events (defined as a composite of SpO2 < 94% in the post-anesthesia care unit, additional oxygen supplementation during ward transfer or stay, and emergency use of sugammadex in the post-anesthesia care unit), the incidence of these effects was compared in propensity score matched groups of patients treated with sugammadex or pyridostigmine. Of the 602 patients, 210 remained in each group after propensity score matching. The incidence of post-operative respiratory adverse events did not differ significantly in the two groups. These findings suggest that the unrestricted administration of sugammadex not preceded by intra-operative deep neuromuscular blockade does not have clinical benefits, when compared with pyridostigmine, in preventing post-operative respiratory adverse events.

Background The consumption of recreational and medicinal cannabis in the United States continues to increase. Understanding the effects of cannabis in patients undergoing elective primary breast augmentation (EPBA) is of paramount importance with the expanding rates of reported cannabis consumption. Objectives This study aims to analyze the peri-operative impact of cannabis use in conjunction with EPBA in a single-surgeon practice in San Francisco, California. Methods A retrospective chart review was performed of 134 adult female patients undergoing EPBA from August 2018 to January 2022 within a single-surgeon practice plastic surgery office. Cannabis use was self-reported as current use or former use. Cohorts were grouped as cannabis users and cannabis non-users. Results Of the 134 patient charts identified for analysis, 58 (43.3%) reported cannabis use. Cannabis users were significantly younger than cannabis non-users (26.8 years versus 31.5 years, P <0.001). No significant differences were found between groups among intra-operative blood loss, post-operative complication rates, post-operative narcotic use, or intra-operative anesthetic requirements. The incidence of adverse events, including wound breakdown, skin necrosis, and capsular contracture requiring reoperation, did not differ significantly between cannabis users and cannabis non-user groups. Ninety-six percent of patients had their implants placed subpectorally, and all procedures were done using a Keller funnel. Eighty-three percent of patients had Sientra implants, and 96% of all implants were silicone gel implants. All procedures were done under general anesthesia. Patients were followed for up to two years. Discussion This review found no significant differences in peri-operative and post-operative outcomes between cannabis users and cannabis non-users., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Mehta et al.)

Background/Aim: Older patients are considered to bear a higher perioperative risk. Since idiopathic normal pressure hydrocephalus (NPH) predominantly concerns older patients, identifying risk factors for early shunt failure for preoperative risk/benefit assessment is indispensable for indication and/or consultation of patients for ventriculoperitoneal shunting (VPS).Methods: We performed a retrospective study design, including data acquired from two university hospital neurosurgical institutions between 2012 and 2019. Overall, 211 consecutive patients with clinical/radiological signs for NPH who additionally showed alleviation of symptoms after lumbar cerebrospinal fluid (CSF) drainage, received VPS and were included for further analysis. Frailty was measured using the Clinical Frailty Scale (CFS). Main outcome was early shunt failure or post-operative complications within 30 days after initial VPS surgery.Results: The overall complication rate was 14%. Patient-related complications were observed in 13 patients (6%) and procedure-related complications in 16 patients (8%). Early post-operative complications resulted in a significantly prolonged length of hospital stay 6.9 ± 6.8 vs. 10.8 ± 11.8 days (p = 0.03). Diabetes mellitus with end-organ damage (OR 35.4, 95% CI 6.6 – 189.4, p < 0.0001) as well as preexisting Parkinson's disease were associated with early patient-related post-surgical complications after VPS for NPH.Conclusions: Patients comorbidities but not frailty were associated with early post-operative patient-related complications in patients suffering NPH. While frailty may deter patients from other (neurosurgical) procedures, VPS surgery might contribute to treating NPH in these patients at a tolerable risk.

Abstract Background Treatment for tracheoesophageal fistula (TEF), a life-threatening complication after esophagectomy, is challenging. Case presentation A 75-year-old man with thoracic esophageal cancer underwent subtotal esophagectomy and gastric tube reconstruction through the post-mediastinal root after neoadjuvant chemotherapy. Owing to postoperative anastomotic leakage, an abscess formed at the anastomotic region. Sustained inflammation from the abscess caused refractory TEF between the esophagogastric anastomotic site and membrane of the trachea, and several conservative therapies for TEF failed. Hence, the patient underwent surgery including division of the fistula, direct suturing of the leakage sites, and reinforcement with the flap of the thymus pedicle. As a result, the abscess and TEF disappeared after surgery and the patient was immediately administered an oral diet and discharged home 103 days after initial surgery. Conclusions Although pedicle flaps for the reinforcement of TEF are usually obtained from muscle or pericardium, these flaps need enough lengths to overcome moving distance. We are the first in the existing literature to have successfully treated TEF with surgical repair using a thymus flap located close to TEF. The thymus pedicle might be another candidate for the reinforcement flap in TEF.

Background: Single-port laparoscopic cholecystectomy (SPLC) is a new advanced technique in laparoscopic surgery which has many benefits according to previous reports. The purpose of this study was to present personal experiences with SPLC in >800 cases performed by a surgeon to evaluate the safety and feasibility of this procedure. Materials and Methods: A retrospective review of 817 cases of SPLC was conducted. All patients had received elective SPLC by a surgeon in our centre during March 2009–August 2015. Our review suggests patients’ character, peri-operative data and post-operative outcome. Results: Three hundred and ninety-eight men (48.7%) and 419 women (51.3%) with an average age of 48.3 years had received SPLC. Their mean body mass index (BMI) was 23.75 kg/m2. The mean operating time took 46.9 min (19–130). Seventy-nine cases (9.7%) needed additional port during operation. BMI, age and previous abdominal surgical history did not affect conversion to multiport surgery. Bile spillage during operation occurred in 73 cases (8.9%). There were 4 cases of open conversion because of bleeding (2 cases, 0.2%) and common bile duct (CBD) injury (2 cases, 0.2%). Mean duration of hospital stay was 2.36 days. We have experienced 38 cases (4.7%) of post-operative complication: 8 cases (1.0%) of major one and 30 cases (3.7%) of minor one. Major complication occurred in 3 cases (0.4%) of retained CBD stone, 3 cases (0.4%) of cystic duct leakage needed endoscopic retrograde cholangiopancreatography and 2 cases (0.2%) of CBD injury needed reoperation. Most minor complications were wound infections that have healed after conservative treatment. There were no post-operative mortalities. Conclusion: SPLC is a safe and practicable technique. With surgical experience, criteria and area of SPLC can be broadened. SPLC is occupying a greater domain of a laparoscopic cholecystectomy.

Background: Conservative surgical approaches, reconstructive techniques and technology are increasingly used in parotid surgery. The aim of this study was to determine the surgeon‐modifiable factors which impact the rates of post‐operative complications following parotidectomy for benign pathology. Methods: A retrospective cohort study of patients undergoing parotidectomy for benign pathology by or under the supervision of the senior author between 2006 and 2019 was performed. Clinicopathological variables, operative techniques and post‐operative complications were recorded using standardized templates. Multivariable logistic regression models were used to obtain odds ratios (ORs) whilst adjusting for the effect of other clinically relevant covariates. Results: In total, 357 parotidectomies were performed. Independent factors associated with post‐operative facial paresis were re‐operative surgery (OR 3.51, 95% CI 1.19–10.33, P = 0.023), nerve integrity monitoring (OR 0.50, 95% CI 0.26–0.99, P = 0.046) and operation type, with focused tumour dissection (FTD) having the lowest rate of paresis (OR 0.19, 95% CI 0.040–0.92, P = 0.038) compared to limited parotidectomy. Factors associated with reduced wound complications on adjusted analysis were dermofat grafting (OR 0.10, 95% CI 0.01–0.72, P = 0.023), lesion size (OR 0.68, 95% CI 0.50–0.92, P = 0.01) and FTD (OR 0.16, 95% CI 0.05–0.59, P = 0.005) compared to limited parotidectomy. Conclusion: FTD, nerve integrity monitoring and dermofat grafting are surgeon‐modifiable variables associated with lower rates of post‐operative complications following parotidectomy for benign pathology. However, the benefit of these operative techniques relies on their appropriate utilization by performing surgeons. [ABSTRACT FROM AUTHOR]

Background: The high and increasing rate of opioid use is a serious issue in the Western world affecting the population's physical and mental health. In most cases, opioid dependency starts with prescriptions by medical professionals, so efforts aimed at reducing in‐hospital opioid use should result in less long‐term dependency. The aim of the current study was to evaluate the feasibility of implementing an opioid‐scarce protocol as part of a new online modifiable Enhanced Recovery After Surgery (mERAS) programme. Methods: A single‐centre retrospective study was conducted comparing a cohort treated under the new opioid‐scarce mERAS protocol (n = 96; May 2018–Nov 2018) to those treated under the original ERAS protocol (n = 84; November 2017–April 2018). The primary outcome was the quantity and duration of opioid use. Results: Fewer patients used fentanyl via intravenous patient‐controlled analgesia in the mERAS group (54% versus 70%; P = 0.03). The mERAS group was also less likely to use oral oxycodone (80% versus 99%; P < 0.0001) and for a shorter duration (median 3 versus 5 days; P = 0.0002). More local anaesthetic transversus abdominis plane catheters were used in the mERAS group (34% versus 6% in the control group; P < 0.0001). Conclusion: Opioid use can be significantly reduced after elective colorectal surgery by employing an opioid‐scarce ERAS protocol. Further data is required to confirm the clinical benefits of this approach. [ABSTRACT FROM AUTHOR]

Background: Angiotensin-converting enzyme inhibitor (ACE-I) and angiotensin-receptor blocker (ARB) users may be associated with increased mortality in patients with post-operative acute kidney injury (AKI), but data are limited. We studied whether users of ACE-I/ARBs with AKI after colorectal cancer surgery (CRC) were associated with increased 1-year mortality after AKI.Methods: This population-based cohort study in Northern Denmark included patients with AKI within 7 days after CRC surgery during 2005-2014. From reimbursed prescriptions, patients were classified as ACE-I/ARB current, former, or non-users. We computed the cumulative 30-day and 1-year mortality after AKI with 95% confidence intervals (95% CI) using the Kaplan-Meier method (1-survival function). Hazard ratios (HRs) comparing mortality in current and former users with non-users were computed by Cox proportional hazards regression analyses, controlling for potential confounders.Results: We identified 10 713 CRC surgery patients. A total of 2000 patients had AKI and were included. Thirty-day mortality was 16.5% (95% CI 13.7-19.8), 16.2% (95% CI 11.3-22.8), and 13.4% (95% CI 11.6-15.4) for current, former, and non-users. Adjusted HR was 1.26 (95% CI 0.96-1.65) and 1.19 (95% CI 0.78-1.82) for current and former users compared with non-users. One-year mortality rates were 26.4% (95% CI 22.9-30.4), 29.8% (95% CI 23.2-37.8), and 24.7% (95% CI 22.4-27.2) in current, former, and non-users. Compared with non-users, the adjusted 1-year HR for death in current and former users were 1.29 (95% CI 0.96-1.73) and 1.11 (95% CI 0.91-1.35).Conclusion: Based on our findings, current users of ACE-I/ARB may possibly have a small increase in mortality rate in the year after post-operative AKI, although the degree of certainty is low.

Background: Gluteal compartment syndrome is an uncommon condition and can be difficult to diagnose. It has been diagnosed after trauma, vascular injury, infection, surgical positioning, and prolonged immobilization from drug or alcohol intoxication. The diagnosis is based on clinical findings and, in most cases, recognizing these symptoms and making a diagnosis early is critical to a complete recovery. Case presentation: A 53-year-old male who underwent left foot surgery had severe pain to his contralateral hip and posterior gluteal compartment radiating to the right lower extremity immediately postoperative. He was positioned supine with a "bump" placed under his right hip to externally rotate his operative leg during the surgery. Due to the patient's complex past medical history, a presumptive diagnosis of a herniated disc and/or compression of the sciatic nerve was made as a cause for the patient's pain. This resulted in a misdiagnosis period of 36 h until the patient was diagnosed with unilateral gluteal compartment syndrome. Performing a fasciotomy was decided against due to the increased risk of complications. The patient was treated with administration of IV fluids and closely monitored. On post-op day 6, the patient was discharged. At three months post-op, the patient was walking without a limp and he had no changes in his peripheral neurologic examination compared to his preoperative baseline. Conclusion: Gluteal compartment syndrome is a surgical emergency that must be considered postoperatively especially in obese patients with prolonged operation times who experience acute buttock pain. The use of positional bars or "bumps" in the gluteal area should be used with caution and raise awareness of this complication after orthopedic surgeries. [ABSTRACT FROM AUTHOR]
