Abstract

Background: As a modification of the duodenal switch (DS), single-anastomosis duodenal-ileal bypass with sleeve gastrectomy (SADI-S) has recently become very popular and is successful for weight loss and T2DM remission. However, current studies have been mostly aimed at patients with severe obesity.

Objectives: In this study, we firstly compare primary SADI-S to the Roux-en-Y gastric bypass (RYGB) in Chinese with diabetes and BMI< 35 kg/m.

Methods: Using a propensity score (PS) matching analysis, we analyzed all patients with diabetes and BMI< 35 kg/m who underwent primary SADI-S or RYGB. All surgeries were conducted by a single surgeon at a Chinese center from June 2017 to January 2019.

Results: Twenty-six patients who underwent SADI-S and 65 patients who underwent RYGB were included in our analysis. Of these, 26 (100%) of patients in the SADI-S group and 43 (66%) of patients in the RYGB group completed the 24-month follow-up. No severe perioperative complication was observed in either group. There was a statistically higher percentage of total weight loss with SADI-S at the 2-year follow-up when compared to RYGB (p = 0.017 after PS correction). After PS adjustment, 76.5% of patients in the SADI-S group and 82.4% of patients in the RYGB group achieved complete remission of T2DM (p = 1.000). Nutritional outcomes were similar in the two groups.

Conclusion: In Chinese with diabetes and BMI< 35 kg/m, with comparable T2DM remission and nutritional outcomes, primary SADI-S allows for better weight loss than RYGB. Compared with RYGB, SADI-S is also a safe, effective, and feasible treatment for these patients.
