Endoscopic papillary large balloon dilation as a salvage procedure for basket impaction during retrieval of common bile duct stones

摘要

Endoscopic management of common bile duct stones (CBDSs) is an effective and minimally invasive procedure. CBDSs are retrieved using either a balloon or basket catheter after managing the major papilla with endoscopic sphincterotomy (ES) or endoscopic papillary balloon dilation (EPBD). However, this procedure is associated with complications such as pancreatitis, hemorrhage, perforation, and cholangitis [1, 2]. Although basket impaction at the papilla during stone retrieval is a rare complication with a reported incidence rate of 0.8 % [3], it can cause serious complications such as biliary obstruction and secondary cholangitis. Furthermore, attempts to release the basket impaction by forceful manipulation can lead to perforation of the duodenum or CBD that will eventually require surgery to resolve the complication.
