Immediate or Interval Endoscopic Papillary Large-balloon Dilation after Limited Endoscopic Sphincterotomy for Bile Duct Stone Removal

Abstract Objective : Endoscopic papillary large-balloon dilation (EPLBD) with limited endoscopic sphincterotomy (EST) is widely used for removing multiple large common bile duct (CBD) stones. However, the safety and effectiveness of immediate EPLBD after limited EST and EPLBD at an interval after limited EST is unclear. Thus, this multicenter retrospective study was conducted to examine this matter. Methods : Propensity score-matching was performed to adjust the baseline characteristics between the immediate and interval EPLBD groups. We compared the incidence of
