Amputation neuromas of the biliary tract are rare benign lesions, most of them follow cholecystectomy. A case of amputation neuroma of the common bile duct following gastrectomy is presented. A 52-year-old man was hospitalized because of obstructive jaundice, which had been noticed one and half year earlier and transient. He had had gastrectomy for duodenal ulcer six months before the first onset of jaundice. A percutaneous transhepatic cholangiogram had first shown narrowing of the common bile duct, which had developed to complete obstruction in the course of one and half year. No malignant findings were obtained by cytological examination of-the bile, preoperatively. On laparotomy, a 4×2 cm mass was found in the choledochal area. However, no maligant change was seen in frozen sections. Cholecystectomy and resection of the common bile duct with reconstruction by Roux-en-Y hepaticojejunostomy were performed. A permanent section confirmed that the lesional tissue was amputation neuroma. He is well and free of jaundice 30 months later.
