ABSTRACT
BACKGROUND:
This meta-analysis aimed to compare the incidence of gallstone formation, subsequent biliary disease and the need for cholecystectomy in untreated patients and patients treated with ursodeoxycholic acid (UDCA) following bariatric surgery.METHODS:
Randomized controlled trials (RCTs) comparing UDCA and controls for the prevention of gallstone formation after bariatric surgery published until February 2022 were selected and subjected to a systematic review and meta-analysis. Articles were searched in the MEDLINE, Web of Science and Cochrane Trials Register databases. Meta-analysis was performed with Review Manager 5.0.RESULTS:
Eleven randomized controlled studies were included, with a total of 2363 randomized patients and 2217 patients analysed in the UDCA group versus 1415 randomized patients and 1257 patients analysed in the control group. Considering analysed patients, prophylactic use of UDCA was significantly associated with decreased (i) gallstone formation (OR = 0.25, 95% CI = 0.21-0.31), (ii) symptomatic gallstone disease (GD) (OR = 0.29, 95% CI = 0.20-0.42) and consequently (iii) cholecystectomy rate (OR = 0.33, 95% CI = 0.20-0.55). The results were similar in ITT analysis, in the subgroup of patients undergoing sleeve gastrectomy or considering only randomized versus placebo studies.CONCLUSIONS:
Prophylactic use of UDCA after bariatric surgery prevents both gallstone formation and symptomatic GD and reduces the need for cholecystectomy.Palavras-chave
