Abstract

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/m2. 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 < 6% with or without the use of diabetic medication. There was a statistically significant difference between most of the pre-operative and post-operative nutritional data.

Conclusions

SADI-S is a safe and effective procedure in both short- and mid-term data points. Diabetes resolution and weight loss appear similar to traditional RYDS and better than RYGB.
