چکیده
AIM To evaluate early and late outcomes of endoscopic papillary large balloon dilation (EPLBD) with minor endoscopic sphincterotomy (mEST) for stone removal. METHODS A total of 149 consecutive patients with difficult common bile duct (CBD) stones (diameter ≥ 10 mm or ≥ 3 stones) underwent conventional endoscopic sphincterotomy (EST) or mEST plus EPLBD from May 2012 to April 2016. Their demographic, laboratory and procedural data were collected, and pancreaticobiliary complications were recorded. RESULTS Sixty-nine (94.5%) of the patients in the EPLBD + mEST group and 64 (84.2%) in the conventional EST group achieved stone clearance following the first session (P = 0.0421). The procedure time for EPLBD + mEST was shorter than for EST alone (42.1 ± 13.6 min vs 47.3 ± 11.8 min, P = 0.0128). The overall rate of early complications in the EPLBD + mEST group (11%) was lower than in the EST group (21.1%); however, the difference was not significant (P = 0.0938). The cumulative recurrence rate of cholangitis and CBD stones between the two groups was also similar. The procedure time was independently associated with post-endoscopic retrograde cholangiopancreatography pancreatitis (OR = 6.374, 95%CI: 1.193-22.624, P = 0.023), CBD stone diameter ≥ 16 mm (OR = 7.463, 95%CI: 2.705-21.246, P = 0.0452) and use of mechanical lithotripsy (OR = 9.913, 95%CI: 3.446-23.154, P = 0.0133) were independent risk factors for stone recurrence. CONCLUSION EPLBD with mEST is more effective than EST alone for difficult CBD stone removal, with shorter procedure time and fewer early complications.

Endoscopic biliary large-balloon dilation after endoscopic sphincterotomy for the treatment of large common bile duct stones. Case report.
Common bile duct (CBD) stones extraction is usually performed by endoscopic sphincterotomy followed by removal by either a Dormia basket or extraction balloon catheter. However, some stones due to their size are not amenable to these procedures and extracorporeal or mechanical lithotripsy devices need to be used. Mechanical lithotripsy involves usage of a basket that will be inevitably destroye...

BACKGROUND/AIMS We evaluated the efficacy and cost-effectiveness of endoscopic papillary large balloon dilation (EPLBD) for large common bile duct (CBD) stone removal compared with endoscopic sphincterotomy (EST). METHODS A total of 1,580 patients who underwent endoscopic CBD stone extraction between January 2001 and July 2010 were reviewed. The following inclusion criteria were applied: chol...
متن کاملEndoscopic Papillary Large Balloon Dilation: Guidelines for Pursuing Zero Mortality
Since endoscopic papillary large balloon dilation (EPLBD) is used to treat benign disease and as a substitute for conventional methods, such as endoscopic sphincterotomy plus endoscopic mechanical lithotripsy, we should aim for zero mortality. This review defines EPLBD and suggests guidelines for its use based on a review of published articles and our large-scale multicenter retrospective review.
