Abstract
The case pertains to a 73-year-old man, who underwent cholecystectomy for cholecystolithiasis at another institute in June, 1998. Postoperative jaundice was observed and end anastomosis was conducted on the bile duct four days following surgery upon a diagnosis for bile duct injury. Jaundice and hepatic dysfunction appeared from 2001. A bile duct stent was endoscopically placed against stenosis of the biliary anastomosis in October 2001 and was repeatedly replaced thereafter. Cholangitis frequently appeared from 2010, leading to his referral to our department for surgery. An expanded intrahepatic bile duct, biliary anastomosis stenosis, and intrahepatic stone were observed upon imaging. Bile duct resection of the anal side, intrahepatic stone removal, and choledochojejunostomy were conducted in October 2011 upon diagnosis for stricture following bile duct injury. Bile duct amputation neuroma was diagnosed at the postoperative histopathological examination. Bile duct amputation neuroma is a rare disease appearing following biliary tract surgery and takes a long time until postoperative onset. However, an investigation into cases reported in Japan revealed that it frequently appears at an early stage following bile duct surgery compared to other surgeries, so the present case must be kept in mind regarding bile duct strictures generated during the early postoperative period.
