Abstract
Untreated benign biliary stricture can lead to serious complications including recurrent cholangitis, biliary cirrhosis, hepatic failure, and death. Benign stricture of a postoperative anastomosis site is also a problematic issue after biliary surgery. Percutaneous transhepatic cholangioscopy (PTCS) with balloon dilatation is a recently introduced noninvasive therapeutic option for biliary stricture. Guidewire insertion through the stricture site is essential for the success of PTCS treatment. Recently, we treated a difficult case with complete bilioenteric anastomosis stricture that failed to allow passage of the guidewire for balloon dilation. The stricture was treated with artificial bilioenteric fistula using a needle-knife papillotome during the PTCS.
