A Preliminary Comparison of Endoscopic Sphincterotomy, Endoscopic Papillary Large Balloon Dilation, and Combination of the Two in Endoscopic Choledocholithiasis Treatment

Abstract Background: Endoscopic retrograde cholangiopancreatography (ERCP) is commonly performed to remove bile duct stones. Endoscopic sphincterotomy (EST), endoscopic papillary large balloon dilation (EPLBD), and endoscopic sphincterotomy plus large balloon dilation (ESLBD) are 3 methods used to enlarge the papillary orifice, but their efficacy and safety remains controversial. This study aimed to compare these methods for treating common bile duct (CBD) stones. Material/Methods: Between July 2011 and December 2013, 255 consecutive patients with proven CBD stones were randomly assigned to EST,
