Late Complications and Stone Recurrence Rates after Bile Duct Stone Removal by Endoscopic Sphincterotomy and Large Balloon Dilation are Similar to Those after Endoscopic Sphincterotomy Alone

Abstract Background/Aims: Between endoscopic sphincterotomy (ES) alone and combined endoscopic sphincterotomy and large balloon dilation (ES-LBD) groups, efficacy and long-term complications, difference in biliary stone recurrence rate, and risk factors of stone recurrence were compared. Methods: Medical records of 222 patients who underwent ERCP for biliary stone removal were retrospectively reviewed. Patients with dilated CBD ≥11 mm and follow-up longer than 6 months were included. Results: There were 101 patients in ES-LBD group and 121 patients in ES group. Mean
