Roux-En-Y Gastric Bypass Versus Sleeve Gastrectomy Plus Procedures for Treatment of Morbid Obesity: Systematic Review and Meta-Analysis

AbstractSleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) are the most commonly performed bariatric procedures globally, but both techniques have shortcomings. Several modifications of SG (SG plus procedures) have been developed, but the efficacy of the different procedures has not been completely elucidated. In this meta-analysis, we aimed to evaluate the efficacy and safety of SG plus procedures. Out of the initially identified 2357 studies, thirteen were selected for this meta-analysis: two studies on banded sleeve gastrectomy (BSG), four studies on sleeve gastrectomy plus duodenal –jejunal bypass (SG + DJB) or sleeve gastrectomy with loop duodenal–jejunal bypass (SADJB), two studies on sleeve gastrectomy with jejunal–jejunal bypass (SG + JJB), four studies on single anastomosis duodenal–ileal switch (SADI-S), and one study on stomach intestinal pylorus–spari ng surgery (SIPS). SADI-S procedure was found to achieve significantly greater percentage of excess weight loss than the RYGB. SG + DJB and SADJB achieved greater weight loss than the RYGB. Major complications were fewer with SG + JJB than with RYGB, but the difference was not significant. O verall, SG plus procedures appear to achieve better weight loss and cause fewer complications than RYGB.Graphical abstract
