METHODS: We compared prospectively SES + ELBD (group A, n = 27) with conventional EST (group B, n = 28) for the treatment of large bile duct stones (≥ 15 mm). When the stone could not be removed with a normal basket, mechanical lithotripsy was performed. We compared the rates of complete stone removal with one session and application of mechanical lithotripsy. RESULTS: No significant differences were observed in the mean largest stone size (A: 20.8 mm, B: 21.3 mm), bile duct diameter (A: 21.4 turn, B: 20.5 ram), number of stones (A: 2.2, B: 2.3), or procedure time (A: 18 min, B: 19 rain) between the two groups. The rates of complete stone removal with one session was 85% in group A and 86% in group B (P = 0.473). Mechanical lithotripsy was required for stone removal in nine of 27 patients (33%) in group A and nine of 28 patients (32%, P = 0.527) in group B.CONCLUSION: SES + ELBD did not show significant benefits compared to conventional EST, especially for the removal of large (≥ 15 mm) bile duct stones.展开更多

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 a展开更多

However, as the efficacy of endoscopic papillary largeballoon dilatation(EPLBD) becomes widely recognized, EPBD is attracting attention. Here we investigate whether EPBD is truly a risk factor for PEP, and seek safer and more effective EPBD procedures by reviewing past studies. We reviewed thirteen randomised control trials comparing EPBD and endoscopic sphincterotomy(EST) and ten studies comparing direct EPLBD and EST. Three randomized controlled trials of EPBD showed significantly higher incidence of PEP than EST, but no study of EPLBD did. Careful analysis of these studies suggested that longer and higher-pressure inflation of balloons might decrease PEP incidence. The paradoxical result that EPBD with small-calibre balloons increases PEP incidence while EPLBD does not may be due to insufficient papillary dilatation in the former. Insufficient dilatation could cause the high incidence of PEP through the use of mechanical lithotripsy and stress on the papilla at the time of stone removal. Sufficient dilation of the papilla may be useful in preventing PEP.展开更多
