Debates still exist about the need for prevention and the selection of preventive methods. No studies had been reported comparing the efficacy of prophylactic ursodeoxycholic acid (UDCA) and prophylactic cholecystectomy (PC) for lowering postsurgical gallstone formation and subsequent cholecystectomy (SC) in patients who have undergone gastric surgery.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We did a systematic review to identify studies from PUBMED, EMBASE, and the Cochrane database through 30 June 2020. We conducted direct and indirect comparisons of each prophylaxis using conventional and network meta\u2010analysis.

The UDCA group showed a tendency to generate more gallstones (OR 3.74, [95% CI 0.88, 15.82]) and a greater need for SC (OR 2.19, [95% CI 0.47\u201010.14]) than did the PC group without statistical significance.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Prophylaxis for gallstone formation may be needed for patients who undergo gastric surgery to reduce troublesome morbidities. Prophylactic UDCA seems to be a reasonable preventive method for postsurgical gallstone formation to ensure clinical benefit while reducing the burden of subsequent cholecystectomy for the patient as
