AI Article Synopsis

Article Abstract

Background: National data show a trend favoring laparoscopic sleeve gastrectomy (SG) over Roux-en-Y gastric bypass (RYGB). Published data demonstrating the differences in weight loss between the two procedures are mixed.

Objective: In this retrospective study using clinical data from 2010 to 2020, we compared the clinical and demographic characteristics of patients undergoing either SG or RYGB to evaluate their long-term weight loss outcomes.

Setting: University hospital in the United States.

Methods: A total of 3329 patients were identified in our institutional Metabolic and Bariatric Surgery Accreditation and Quality Improvement database using Current Procedural Terminology codes for either RYGB or SG. A general linear model was used for baseline characteristics. Logistic regression was used for factors favoring RYGB versus SG. A multivariable linear mixed model was used for weight-trajectory analysis. Cox regression was used for a cumulative hazard ratio of 10% weight regained from nadir.

Results: Factors favoring RYGB were diagnoses of type 2 diabetes and gastroesophageal reflux disease, Hispanic ethnicity, and surgeon's preference. SG was favored among Black patients and smokers. RYGB was associated with more weight loss at all time points. The risk of weight regain was significantly higher after SG versus RYGB.

Conclusions: The bariatric procedure choice is significantly influenced by race, medical history, and surgeon's experience. RYGB results in a significantly more durable weight loss compared with SG regardless of race or other stratification factors.
