Weight reduction and the risk of gallbladder and biliary disease: A systematic review and meta‐analysis of randomized clinical trials.

Summary: In this meta‐analysis, we aim to evaluate the risk of gallbladder and biliary disease of weight management strategies and investigate the association between weight reduction and risk of gallbladder or biliary disease. Randomized controlled trials (RCTs) with a duration of at least 12 weeks that compare antiobesity medications (AOMs) with placebo or bariatric surgery with less intensive weight management strategy were concluded. Weight management strategy was associated with a significant increased risk of gallbladder or biliary disease (OR 1.361, 95% CI 1.147 to 1.614, P < 0.001, I2 = 3.5%), cholelithiasis, cholecystitis, and cholecystectomy compared with placebo or controls. The increased risk of gallbladder or biliary disease was observed both in pharmacotherapies subgroup and bariatric surgery subgroup. With regards of specific pharmacotherapies, an increased risk of gallbladder or biliary disease was observed in trials with glucagon‐like peptide 1 receptor agonist (GLP‐1 RA) treatments. In addition, trials with indication of obesity and overweight treatment and trials with higher doses showed significant higher risk of gallbladder or biliary disease compared with placebo or controls. In conclusion, weight management strategy was associated with an increased risk of gallbladder or biliary disease when compared with placebo or control groups. [ABSTRACT FROM AUTHOR]
