BACKGROUND
The effect of reinforcement technique is still controversial in bariatric surgery, and variations may exist in using this technique.
OBJECTIVE
This study aims to survey the views of bariatric surgeons on reinforcement technique and evaluate the effects of applying reinforcement technique in sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB).
METHODS
This study is mainly composed of two parts. Part 1 will investigate the differences of using reinforcement technique among surgeons worldwide who perform SG/RYGB through survey. And the survey will be conducted by email and social media. Part 2 is to evaluate the safety and effectiveness of using omentopexy/staple line reinforcement in SG and RYGB by systematic review and meta-analysis. In this part, literature searches will be performed in databases of Wanfang, China National Knowledge Infrastructure, Database for Chinese Technical Periodicals, Chinese Biological Medicine, PubMed, Web of science, Embase, and Cochrane Library from their establishment to March 2023. Randomized controlled trials and case-control studies will be included. The primary outcomes are rates of postoperative bleeding and gastric leakage. And the secondary outcomes include anastomotic stenosis, surgical site infection, re-operation, estimated intraoperative blood loss, operative time (minutes), hospital length of stay (days), overall complications, and 30-day mortality. Meta-analysis will be conducted by Revman 5.4 under the random-effects model, as well as extensive subgroup and sensitivity analyses. P-value <0.05 will be considered statistically significant.
