Abstract
Background: Billroth I, Billroth II, Roux-en-Y, and Un-cut Roux-en-Y are common reconstruction techniques of distal gastrectomy. Which of these techniques is better has yet to be established. We performed an indirect comparison to evaluate which technique was optimal for preventing reflux symptoms.
Methods: The PubMed, Cochrane Collaboration, Embase, ClinicalTrials.gov and Web of Science databases were searched to identify clinical trials that compared at least two of the reconstruction skills among Billroth I, Billroth II, Roux-en-Y, and Un-cut Roux-en-Y. Data on reflux gastritis, intraoperative blood loss, bile reflux and postoperative hospital stays were extracted from the included clinical trials for meta-analysis using a random-effects model.
Results: Twenty-four articles that included 5419 individuals were assessed as eligible for meta-analysis. The indirect comparison suggested that Roux-en-Y reconstruction significantly reduces reflux gastritis, and it tended to rank first and had the highest probability of preventing bile reflux. No significant differences were found in intraoperative blood loss and postoperative hospital stays.
Conclusion: This indirect comparison suggested some superiority of Roux-en-Y reconstruction after distal gastrectomy. Further perspective clinical trials are required to provide evidence for the optimal reconstruction skill.
