AIM To evaluate early and late outcomes of endoscopic papillary large balloon dilation(EPLBD) with minor endoscopic sphincterotomy(m EST) 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 m EST 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 + m EST 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 + m EST 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 + m EST 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 m EST is more effective than EST alone for difficult CBD stone removal, with shorter procedure time and fewer early complications.
