Postoperative benign biliary stricture successfully treated using percutaneous balloon dilatation after cauterization using Nd-YAG laser

64-year-old female had extrahepatic bile duct resection with choledochoduodenostomy for cystoma of the common bile duct. Fifteen years later, a bilateral hepaticojejunostomy was required due to the presence of bilioenteric anastomotic stricture. Nevertheless, cholangitis repeatedly recurred. Percutaneous balloon dilatation for stricture of the bilioenteric anastomosis was ineffective. Therefore, the stricture of the bilioenteric anastomosis was cauterized using Nd-YAG laser with percutaneous transhepatic cholangioendoscopy. Balloon dilatation was then performed. A favorable degree of dilatation was achieved, and long-term catheter insertion was avoided.
