Single Anastomosis Duodeno-ileal Bypass As a Revisional Procedure Following Sleeve Gastrectomy: Review of the Literature.

Laparoscopic sleeve gastrectomies (LSGs) can experience weight-loss failure and conversion to another bariatric procedure. An analysis of the bariatric literature concerning the single anastomosis duodeno-ileal bypass with sleeve gastrectomy (SADI-S) as revisional surgery after LSG in terms of safety and efficacy identified 607 studies. Fifty-nine studies were analyzed for full content review and 9 primary studies (398 patients) were included. Revisional single anastomosis duodeno-ileal bypass (SADI) was performed in 294 patients at a mean interval of 37.7 months (range 11-179). Total weight loss (%) varies from 20.5% to 46.2%. Early complications after surgery occurred in 4.1% surgeries including leak (7 cases -1.9%). Mortality was nil. SADI after LSG, after failed sleeve gastrectomy or as a sequential procedure, offers a satisfactory weight loss result. Both early and late term complications are acceptable.
