Background Single anastomosis duodenal-ileal bypass with sleeve gastrectomy (SADI-S) is a modification of Roux-en-Y duodenal switch (RYDS). Long-term data on this operation is lacking in the literature. We reviewed our mid-term data of this RYDS modification. Purpose To analyze the outcomes with SADI-S at 4 years. Methods Data from patients who underwent a primary SADI-S procedure performed by three surgeons at a single institution from June 2013 through February 2018 were retrospectively reviewed. All revision bariatric surgeries were excluded. Regression analyses were performed for all follow-up weight loss data. Results There were 437 patients in our database. The pre-operative mean body mass index (BMI) was 49.8 ± 8.8 kg/m 2 . The 30-day complication rate was 7.7%. The 30-day readmission, reoperation, and mortality rates were 1.8, 1.3, and 0.2%, respectively. The long-term complication rate was 10.9%. Seventy-nine patients were 4 years post SADI-S surgery and follow-up was possible for 44 patients (55.7%). At 4 years, patients had an average change in BMI of 18.1 ± 6 units with an excess weight loss (EWL) of 85.7 ± 27.3%. At 4 years, 97.6% patients were able to maintain HbA1c
