Abstract
INTRODUCTION Emergency general surgery (EGS) patients are at increased risk for postoperative morbidity and mortality. Obesity is a risk factor for poor outcomes in this population. Our study aimed to explore the association of body mass index (BMI) with postoperative outcomes in patients requiring common EGS procedures. METHODS A retrospective review of the 2018-2020 National Surgical Quality Improvement Program database identified patients undergoing four common EGS procedures: large bowel resection, small bowel resection, cholecystectomy, and appendectomy. Patients were classified by BMI: normal weight (18.5-24.9 kg/m2), obesity classes I (30-34.9 kg/m2), II (35-39.9 kg/m2), III (40-49.9 kg/m2), and IV (≥50 kg/m2). Main outcomes of interest were major adverse event (MAE) and mortality. RESULTS From 2018 to 2020, a total of 82,540 patients underwent one of four common EGS procedures. On unadjusted analysis, obesity class IV had higher mortality rates compared to classes I-III (6.2% vs 3.1%, P < 0.001). Patients in obesity classes I-III had lower odds of MAE and death relative to those of normal weight. Compared to other patients with obesity, those in obesity class IV were at increased risk of MAE (odds ratio 1.27; 95% confidence interval 1.13-1.44) and death (odds ratio 1.69; 95% confidence interval 1.34-2.13). CONCLUSIONS Patients with varying degrees of obesity have different risk profiles following common EGS procedures. While patients in lower obesity classes had reduced odds of adverse outcomes, those with BMI ≥50 kg/m2 were particularly at greater risk for postoperative morbidity and mortality. This vulnerable population warrants further investigation and increased vigilance to ensure high-quality care.

Conversion from Laparoscopic to Open Appendectomy: Trends, Risk Factors and Outcomes. A 15-Year Single-Center Analysis of 2193 Adult Patients. World J Surg 2022; 46:2642-2647. [PMID: 35871658 PMCID: PMC9309015 DOI: 10.1007/s00268-022-06670-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 07/04/2022] [Indexed: 11/11/2022]
Abstract
Background Laparoscopic appendectomy (LA) has become the standard of care for the management of acute appendicitis in adult patients. Despite the increasing experience in laparoscopy, conversion to open surgery might still occur. We aimed to identify preoperative and intraoperative risk factors for conversion and determine surgical outcomes in this population. Methods We performed a retrospective analysis of a consecutive series of patients undergoing LA during the period 2006–2020. The cohort was divided into two groups: patients who underwent a fully laparoscopic appendectomy (FLA) and patients who were converted to open appendectomy (CA). Demographics, perioperative variables and postoperative outcomes were compared between both groups. Independent risk factors for conversion were determined by logistic regression analysis. Results A total of 2193 patients were included for analysis; 2141 (98%) underwent FLA and 52 (2%) CA. Conversion rates decreased significantly over time (p = 0.006). Patients with CA had significantly higher overall postoperative morbidity rates (FLA 14.9% vs. CA 48.0%, p < 0.0001) and longer mean length of hospital stay (FLA 1.7 vs. CA 5 days). In the multivariate analysis, obesity (p < 0.001), previous abdominal operations (p = 0.013), peritonitis (p = 0.003) and complicated appendicitis (p < 0.001) were independent risk factor for conversion. Conclusions Although conversion from laparoscopic to open appendectomy is infrequent and has decreased over time, it is associated with significantly higher postoperative morbidity. Patients with previous abdominal operations, obesity and complicated appendicitis should be thoroughly advised about the higher risk of conversion.

Abstract
IMPORTANCE Severe obesity is a risk factor for major early complications after total hip arthroplasty (THA). OBJECTIVE To determine the association between surgeon experience with THA in patients with severe obesity and risk of complications. DESIGN, SETTING, AND PARTICIPANTS This retrospective population-based cohort study was performed in Ontario, Canada, from April 1, 2007, to March 31, 2017, with data analysis performed from March 2020 to January 2021. A cohort of patients who received a primary THA for osteoarthritis and who also had severe obesity (body mass index [calculated as weight in kilograms divided by height in meters squared] ≥40) at the time of surgery was defined. These patients were identified using the Canadian Institute for Health Information Discharge Abstract Database and physician claims from the Ontario Health Insurance Plan. Generalized estimating equations were used to determine the association between overall THA and severe obesity-specific THA surgeon volume and the occurrence of complications after controlling for potential confounders. The study hypothesized that surgeon experience specific to patients with severe obesity could further reduce the risk of complications. EXPOSURES Primary THA. MAIN OUTCOMES AND MEASURES Complications were considered as a composite outcome (revision, infection requiring surgery, or dislocation requiring reduction), within 1 year of surgery. This was defined before the study, as was the study hypothesis. RESULTS A total of 4781 eligible patients was identified. The median age was 63 (interquartile range [IQR], 56-69) years, and 3050 patients (63.8%) were women. Overall, 186 patients (3.9%) experienced a surgical complication within 1 year of surgery. The median overall THA surgeon volume was 70 (IQR, 46-106) cases/y, whereas the median obesity-specific surgeon volume was 5 (IQR, 2-9) cases/y. After controlling for patient and hospital factors, greater obesity-specific THA surgeon volume (adjusted odds ratio per additional 10 cases, 0.65 [95% CI, 0.47-0.89]; P = .007), but not greater overall THA surgeon volume (adjusted odds ratio per 10 additional cases, 0.97 [95% CI, 0.93-1.02]; P = .24), was associated with a reduced risk of complication. CONCLUSIONS AND RELEVANCE Increased surgeon experience performing THA in patients with severe obesity was associated with fewer major surgical complications. These findings suggest that surgeon experience is required to mitigate the unique anatomical challenges posed by surgery in patients with severe obesity. Referral pathways for patients with severe obesity to surgeons with high obesity-specific THA volume should be considered.
