A case of amputation neuroma of the common bile duct after cholecystectomy and choledochotomy is reported. A 78-year-o1d man was hospitalized with the complication of jaundice. He had undergone cholecystectomy and choledochotomy four years previously. Percutaneous transhepatic cholangiography and cholangioscopy showed stenosis of the middle bile duct and a choledochal stone. The biopsy specimen revealed adenocarcinoma. Under a diagnosis of bile duct cancer, the common bile duct was resected and choledocho-jejunostomy was performed. The white tumor 1 cm in size was observed at the stenotic lesion of the choledochus and was histologically diagnosed as amputation neuroma. Amputation neuroma is rare, and as far as we investigated, only 30 cases have been reported in Japan. Cases of stricture of the bile duct were difficult to distinguish from bile duct cancer. When the patient has choledochal stenosis after choledochotomy, the possibility of amputation neuroma should be considered.
