The extraction of large common bile duct (CBD) stones after an endoscopic sphincterotomy is successful in most cases. However, the procedure often requires a prolonged time and repeated trials, therefore, subsequent occurrence of procedure-related complications are not uncommon. The purpose of the present paper was to investigate the utility of a combined endoscopic papillary large balloon dilation (EPLBD) preceded by a mid-incision endoscopic sphincterotomy for the removal of large CBD stones. Stone removal was surprisingly effective with EPLBD in patients with large CBD stones. Occurrence of major complication, such as pancreatitis, bleeding, and perforation, was not observed in any patients who were treated with EPLBD. EPLBD also can be safely carried out on patients with anatomic alteration, such as a periampullary diverticulum, and on patients who have undergone a Billroth II operation. EPLBD is a landmark method of removing a large CBD stone, the impact of which is comparable to that of the introduction of endoscopic mechanical lithotripsy. However, further investigation is required to address the applications and potential outcomes of this procedure. Also, procedure guidelines should be established to avoid major complications.
