Endoscopic papillary large balloon dilation (EPLBD) combined with endoscopic sphincterotomy (EST) has been increasingly used to remove large common bile duct (CBD) stones. However, the clinical outcomes of stone extraction have rarely been investigated in regard to the size of the balloon. The aim of this study was to assess the short- and long-term outcomes of 12- and 15-mm EPLBD with a limited EST for large CBD stones.
