- Abstract
Purpose: Compare primary single anastomosis duodeno-ileal bypass with sleeve gastrectomy (SADI-S) and two-stage SADI after sleeve gastrectomy (SG) in terms of weight loss, reduction/remission of comorbidities, and morbidity. Methods: Retrospective study including 179 patients treated laparoscopically between 2016 and 2020. A 50Fr bougie was used for the SG in the primary SADI-S (group 1) and 36/40Fr for the two-stage procedure (group 2). The duodeno-ileal anastomosis was performed at 250 cm from the ileocecal valve and at least 2 cm after the pylorus. Results: Mean age was 44.1 years old, and there were 148 women and 31 men. There were 67 (37.4%) patients in group 1 and 112 (62.6%) in group 2, with 67% completing the 4-year follow-up. Mean preoperative body mass index (BMI) was 51.1 kg/m2 and 44.6 kg/m2 for groups 1 and 2, respectively. Preoperative comorbidities were obstructive sleep apnea, hypertension, type 2 diabetes, and dyslipidemia in 103 (57.5%), 93 (52%), 65 (36.3%), and 58 (32.4%) of cases. At 4 years postoperatively, excess weight loss (EWL) was 67.5% in group 1 and 67% in group 2 (p = 0.1005). Both groups had good comorbidity remission rates. Early postoperative morbidity rate was 10.4% in group 1 and 3.6% in group 2. In group1, there were mostly postoperative intra-abdominal hematomas managed conservatively (n = 4). Two revisional surgeries were needed for duodeno-ileal anastomosis leaks. Postoperative gastroesophageal reflux disease (GERD), daily diarrhea, vitamin, and protein levels were similar in both groups. Conclusion: Both types of strategies are efficient at short and mid-term outcomes. Preoperative criteria will inform surgeon decision between a primary and a two-stage strategy.
