Superiority of 10-mm-wide Balloon over 8-mm-wide Balloon in Papillary Dilation for Bile Duct Stones: A Matched Cohort Study

Abstract Background/Aims: Endoscopic papillary balloon dilation (EPBD) is a possible alternative to endoscopic sphincterotomy (EST) for common bile duct (CBD) stones. To date, 10- and 8-mm EPBD have not been fully compared. Patients and Methods: Patients who underwent EPBD for CBD stones at two Japanese tertiary care centers between May 1994 and January 2014 were identified. Matched pairs with 10- and 8-mm EPBD were generated. Short- and long-term outcomes were compared between the two groups. Results: A total of 869
