Abstract

Difficult common bile duct (CBD) stones are difficult to remove using conventional stone clearance methods such as endoscopic papillary sphincterotomy. In this guideline, we present several recommendations and relevant information on the endoscopic treatment of difficult CBD stones. For the primary treatment of large CBD stones in patients without distal bile duct stricture, we recommend limited endoscopic sphincterotomy followed by endoscopic papillary large balloon dilation. For large CBD stones that are difficult to remove with conventional endoscopic treatment methods, we recommend electrohydraulic or laser lithotripsy under cholangioscopy. Short-term biliary stenting is recommended in patients with CBD stones that are difficult to remove by these methods. Finally, endoscopic treatment via small bowel enteroscopy or percutaneous transhepatic cholangioscopy may be an option in patients with surgically altered anatomy.
