Short-term outcomes after simultaneous gastrectomy plus cholecystectomy in gastric cancer: A pooling up analysis.

The purpose of this study was to evaluate the short-term outcomes after simultaneous gastrectomy plus cholecystectomy in gastric cancer patients. PUBMED, EMBASE, and the Cochrane Library were searched from inception to Apr 15, 2021. Short-term surgical outcomes were compared between the simultaneous gastrectomy plus cholecystectomy group and the gastrectomy only group. Five retrospective studies with 3,315 patients and 1 randomized controlled trial with 130 patients were included. There was no significant difference in age, sex, surgical methods, or reconstruction. In terms of short-term outcomes, no significance was found in postoperative complications (odds ratio, OR = 1.08, = 24%, 95% CI = 0.78-1.50, = 0.65), postoperative biliary complications (OR = 0.98, = 0%, 95% CI = 0.43-2.25, = 0.96), mortality (OR = 1.28, = 0%, 95% CI = 0.49-3.37, = 0.61), and postoperative hospital stay (MD = -0.10, = 0%, 95% CI = -0.73-0.54, = 0.77) between the two groups. Simultaneous gastrectomy plus cholecystectomy in gastric cancer patients is safe and does not increase the short-term outcomes.
