Comparison of Laparoscopic Sleeve Gastrectomy and Laparoscopic Greater Curvature Plication Regarding Efficacy and Safety: a Meta-Analysis.

Laparoscopic sleeve gastrectomy (LSG) and laparoscopic greater curvature plication (LGCP) are two restrictive bariatric procedures. Eight studies (three randomized, controlled trials, four retrospective studies, and one prospective study) with 536 patients on LSG and LGCP were included by searching PUBMED, EMBASE, and the Cochrane Library. The software Review Manager 5.3 was used to evaluate operation time, adverse events, percent excess weight loss (%EWL), resolution of obesity-related comorbidities, and postoperative hospital stay. Despite the limitations, this meta-analysis suggests that LSG is superior to LGCP in terms of providing greater %EWL at the follow-up of 3, 6, and 12 months and 3 years. LSG gains shorter postoperative hospital stay than LGCP. No significant difference was found in operation time, adverse events, and the resolution of obesity-related comorbidities.
