Laparoscopic gastric bypass for the treatment of type 2 diabetes: a comparison of Roux-en-Y versus single anastomosis gastric bypass

Abstract

Background: In recent years, gastric bypass surgery has been found to have therapeutic potential for the treatment of type 2 diabetes (T2D). However, the difference between 2 bypass procedures, Roux-en-Y gastric bypass (RYGB) and another single anastomosis gastric bypass (SAGB), is not clear. Objective: To evaluate the differences between SAGB and RYGB in the efficacy of T2D remission in obese patients. Setting: Tertiary teaching hospital. Methods: Outcomes of 406 (259 women and 147 male) patients who had undergone RYGB (157) or SAGB (249) for the treatment of T2D with 1-year follow-up were assessed. The remission of T2D after surgery was evaluated in matched groups, including body mass index (BMI) and the ABCD scoring system, which comprises patient age, BMI, C-peptide levels, and duration of T2D (yr). Results: The weight loss of the SAGB patients at 1 year after surgery was better than the RYGB patients (24.1% [8.4%] versus 30.7% [8.7%]; P <6.0%) at 1 year after surgery (P
