Abstract

This systematic review of 10 studies aimed to investigate the mid- and long-term results of duodeno-ileostomy with sleeve gastrectomy (SADI-S) according to the PRISMA guideline. Related articles, which reported outcomes of laparoscopic SADI-S with follow-up ≥ 3 years, were selected and analyzed. The percentage of excess weight loss (EWL) was 70.9–88.7%, and 80.4% at 6, and 10 years, respectively. The more common late complications were malabsorption (6.3%) and gastroesophageal reflux disease (GERD) (3.6%). The remission rates of hypertension, diabetes, GERD, obstructive sleep apnea, and dyslipidemia were 62.9%, 81.3%, 53.2%, 60.9%, and 69.7%, respectively. In conclusion, SADI-S is a safe and effective surgical technique with durable weight loss and a high rate of comorbidity resolution in mid and long term.

Key Points

• The SADI-S surgical technique is safe and effective, providing significant sustained mid- and long-term weight loss and resolution of comorbidities.

• SADI-S can be performed as safe and effective revisional surgery after sleeve gastrectomy.

• SADI-S should be performed in appropriately selected patients with dietary and follow-up compliance.
