Gastric Bypass Versus Sleeve Gastrectomy: Comparison of Patient Outcomes, Satisfaction, and Quality of Life in a Single-Center Experience.

Background: Laparoscopic sleeve gastrectomy (LSG) is the most common primary bariatric operation performed in the United States. Its relative technical ease, combined with a decreased risk for anatomic and malabsorptive complications make LSG an attractive option compared to laparoscopic gastric bypass (LGB) for many patients and surgeons. However, emerging evidence for progressive gastroesophageal reflux disease (GERD) after LSG, and the inferior weight loss in many studies, suggests that the enthusiasm for LSG requires reassessment. We hypothesized that patient satisfaction and quality of life (QoL) may be lower after LSG compared to LGB because of these differences. Methods: We distributed a survey querying weight-loss outcomes, complications, foregut symptoms, QoL, and overall satisfaction to patients who underwent bariatric operations at our institution between 2000 and 2020 and who had electronic mail contact information available. Mean follow-up was 2.75 ± 2.41 years for LGB patients and 3.37 ± 2.18 (P = .021) years for LSG patients. We compared these groups for weight-loss outcomes, changes in foregut symptoms, gastrointestinal QoL, postbariatric QoL, and overall satisfaction using appropriate statistical tests. Results: Among 323 respondents, 126 underwent LGB and 197 underwent LSG. LGB patients had larger body mass index (BMI) reduction than LSG patients (-17.16 ± 9.07 kg/m2 versus -14.87 ± 7.4 kg/m2, P = .023). LGB patients reported less reflux (P = .003), with decreased heartburn (P < .0001) and regurgitation (P = .0027). However, a greater proportion of LGB patients reported at least one complication (P = .025). Despite this, more LGB patients reported satisfaction (92.86%) than LSG patients (73.6%). Conclusion: LGB patients are significantly more likely to be satisfied than LSG patients. Factors contributing to the higher level of satisfaction include less GERD and better BMI decrease.

Diagnostic significance of the CT rim sign in cases of gangrenous cholecystitis.

PURPOSE: To evaluate the association between the CT rim sign and gangrenous cholecystitis (GC) and increased surgical difficulty. METHOD: Patients who had a contrast enhanced CT of the abdomen and pelvis, followed by non-elective cholecystectomy were analyzed. The scans were reviewed for the CT rim sign by radiologists blinded to the pathologic and clinical outcomes. Demographic and clinical characteristics were compared between patients with and without GC using t-tests or Wilcoxon ranked sum test for continuous variables, and Fishers' exact test for categorical variables, when appropriate. A logistic regression model was fitted with multiple risk factors. Odds ratios as well as 95% confidence intervals were then calculated for the risk factors. A secondary analysis predicting increased surgical difficulty, defined as an operative time of greater than 2 h or increased conversion rate to open surgery, was also examined. RESULTS: A total of 100 patients were included; 20 of which had GC. On imaging, patients with GC were more likely to have a CT rim sign (65% vs 32.5%, OR = 3.80, 95% CI: 1.24-12.7, p = 0.011). The presence of the CT rim sign did not reach a statistically significant association with an operative time >2 h or conversion to open case (56.52% vs 33.77%, OR = 2.55, p = 0.056). CONCLUSION: The CT rim sign can be utilized to raise the possibility of GC, however the presence of the CT rim sign does not demonstrate an association with increased surgical difficulty.
