METHODS: Randomized controlled trials published from 1990 to 2012 comparing EPBD with EST for CBD stone removal were evaluated. This meta-analysis was performed to estimate short-term and long-term com-plications of these two treatments. The fixed random effect model or random effect model was established to analysis the data. Results were obtained by analyz-ing the relative risk, odds ratio, and 95%CI for a given comparison using RevMan 5.1. Statistical significance was defined asP < 0.05. Risk of bias was evaluated us-ing a funnel plot. RESULTS: Of the 1975 patients analyzed, 980 of them were treated with EPBD and 995 were treated with EST. Of the patient population, patients in the EPBDgroup were younger (OR=-1.16, 95%CI:-1.49 to 0.84, P<0.01). There were no significant differences in gender proportion, average size of stones, number of gallstones, previous cholecystectomy, the incidence of duodenal diverticulum, CBD diameter or the total follow-up time between EST and EPBD groups. Com-pared with EST, the total stone clearance in the EPBD group decreased (OR=0.64, 95%CI: 0.42 to 0.96,P=0.03), the use of stone extraction baskets significantly increased (OR=1.91, 95%CI: 1.41 to 2.59, P<0.01), and the incidence of pancreatitis significantly increased (OR=2.79, 95%CI: 1.74 to 4.45, P<0.0001). The incidence of bleeding (OR=0.12, 95%CI: 0.04 to 0.34, P<0.01) and cholecystitis (OR=0.41, 95%CI: 0.20 to 0.84, P=0.02) significantly decreased. The stone re-currence rate also was significantly reduced in EPBD (OR=0.48, 95%CI: 0.26 to 0.90, P=0.02). There were no significant differences between the two groups with the incidence of stone removal at first attempt, hours of operation, total short-term complications and infection, perforation, or acute cholangitis. CONCLUSION: Although the incidence of pancreatitis was higher, the overall stone clearance rate and risk of bleeding was lower with EPBD compared to EST. 关 键 词：Common BILE duct stone ENDOSCOPIC papil-lary BALLOON DILATATION ENDOSCOPIC sphincteropapilloto-my META-ANALYSIS
