A traumatic neuroma associated with obstructive jaundice after laparoscopic cholecystectomy.

A traumatic neuroma of the biliary tract is rarely associated with biliary obstruction. The authors describe a case of obstructive jaundice that occurred after laparoscopic cholecystectomy. Obstructive jaundice developed in a 39-year-old woman 8 months after laparoscopic cholecystectomy. The stricture was resected and a Rouxen-Y hepaticojejunostomy was performed. Histological examination revealed a traumatic neuroma and a fibrous scar around the biliary duct. To our knowledge, a traumatic neuroma of the biliary tract after laparoscopic cholecystectomy has not been reported previously. Thermal injury may cause the late onset of a fibrous scar and traumatic neuroma. Therefore, traumatic neuroma should be included in the differential diagnosis when late-onset biliary tract obstruction develops after laparoscopic cholecystectomy.
