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.
胆道创伤性神经瘤很少与胆道梗阻相关。作者描述了一例腹腔镜胆囊切除术后发生的梗阻性黄疸病例。一名39岁女性在腹腔镜胆囊切除术后8个月出现梗阻性黄疸。切除狭窄段并进行了Roux-en-Y肝空肠吻合术。组织学检查显示为创伤性神经瘤及胆管周围的纤维瘢痕。据我们所知，此前尚未有腹腔镜胆囊切除术后发生胆道创伤性神经瘤的报道。热损伤可能导致纤维瘢痕和创伤性神经瘤的迟发性发生。因此，当腹腔镜胆囊切除术后出现迟发性胆道梗阻时，鉴别诊断应考虑创伤性神经瘤。
