Weight failure after sleeve gastrectomy (SG) is frequently observed. Consensus on the most effective treatment is lacking. The aim of this meta-analysis was to assess revisional strategies for weight regain (WR) or insufficient weight loss (IWL) following SG. The included studies reported on endoscopic gastroplasty (ESG), re-sleeve gastrectomy (re-SG), Roux-en-Y gastric bypass (RYGB), one-anastomosis gastric bypass (OAGB), single-anastomosis duodeno-ileal bypass (SADI), and duodenal switch (DS). All techniques resulted in clinically relevant weight loss. Although our data suggest that revisional OAGB was the most effective procedure, the lack of direct comparisons precludes strong conclusions. All procedures were feasible but differed regarding complication rates. Choice of procedure is depending on patient’s characteristics and surgeons’ expertise.
