BPD/DS and SADI-S conversion after RYGB had comparable short-term bariatric outcomes and 30-day complication rates in 616 patients.
Does conversion to BPD/DS compared to SADI-S result in different 30-day complication rates and early weight loss in patients with prior Roux-en-Y gastric bypass?
BPD/DS and SADI-S demonstrate comparable short-term safety and early weight loss outcomes when performed as revisional procedures following Roux-en-Y gastric bypass.

Abstract Background Recurrent weight gain (RWG) after Roux-en-Y gastric bypass (RYGB) is an increasingly common challenge. Biliopancreatic diversion with duodenal switch (BPD/DS) and single anastomosis duodeno-ileal bypass with sleeve gastrectomy (SADI-S) are surgical options available for achieving optimal clinical response in these patients. Objectives This study aimed to compare the characteristics and outcomes of patients who underwent either BPD/DS or SADI-S following RYGB. Methods An analysis of the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database was conducted, focusing on patients from 2020 to 2022 who underwent BPD/DS or SADI-S following a primary RYGB. Postoperative bariatric outcomes, complication rates, and weight loss metrics—including percentage of excess weight loss (%EWL), total weight loss (%TWL), and excess BMI loss (%EBMIL) at 30 days—were evaluated. A stratified analysis was also performed to assess differences between the procedures. Results A total of 616 patients were included. 75.5% ( n = 465) underwent BPD/DS and 24.5% ( n = 151) SADI after RYGB. The majority of patients were female (90.7%, n = 559), with a mean age of 48.2 ± 9.1 years. The mean preoperative body mass index (BMI) was 47.5 ± 8.3 for patients undergoing BPD/DS and 44.5 ± 6.8 for those undergoing SADI ( p < 0.001). Patients who underwent BPD/DS had a higher prevalence of hypertension (47% vs. 33.7%, p = 0.004) and ASA IV classification (12.2% vs. 1.3%, p < 0.001), but a lower rate of drain placement compared to those who underwent SADI (31.8% vs. 45%, p = 0.003). There was no statistically significant difference in terms of length of stay, operative time, or intraoperative/postoperative complications in the first 30 days. Weight loss outcomes at 30 days were comparable between the BPD/DS and SADI approaches. Conclusions Among patients undergoing conversion after RYGB, BPD/DS and SADI demonstrated comparable short-term bariatric outcomes, with similar 30-day postoperative complication rates.
