Background/Aims: To compare the efficacy and long-term complications, biliary stone recurrence rate, and risk factors of stone recurrence between endoscopic sphincterotomy (ES) alone and combined ES and large balloon dilation (ES-LBD). Methods: The medical records of 222 patients who underwent endoscopic retrograde cholangiopancreatography (ERCP) for biliary stone removal were retrospectively reviewed. Patients with a dilated common bile duct (CBD; ≥11 mm) who were followed up for >6 months were included. Results: There were 101 patients in the ES-LBD group and 121 patients in the ES group. The mean follow-up duration was 25.0 months (range, 6 to 48) and 13.0 months (range, 6 to 43), respectively (p=0.001). The number of ERCP sessions, brown pigment stones, angle between the mid and distal CBD (<135°), and lithotripsy rate did not differ between groups. The complete retrieval success rate was excellent in both groups (100% vs. 99%). The early complication rate of the ES-LBD and the ES-alone group was 4% and 4.1%, respectively (p=1.000). One patient in the ES-LBD group died of delayed bleeding. The late complication rate was 5.9% and 3.3%, respectively (p=1.000). The stone recurrence rate was 6.9% and 5.8%, respectively (p=0.984). The presence of a periampullary diverticulum was the only independent risk factor of stone recurrence. Conclusions: The late complications and stone recurrence rates were similar between ES-LBD and ES alone.
