Duplication of the extrahepatic bile duct is an extremely rare congenital anomaly of the biliary system.
A 44-year-old woman presented with a history of continuous upper abdominal pain and vomiting.
Magnetic resonance cholangiopancreatography (MRCP) disclosed diffuse dilatation of the intrahepatic and extrahepatic bile ducts. Endoscopic retrograde cholangiopancreatography (ERCP) showed the presence of two extrahepatic bile ducts with calculus at the distal end of the CBD.
Laparoscopic cholecystectomy (LC) was performed after an ERCP. Choledochoscopy, performed during the operation, showed duplicated common bile duct and the cystic duct was seen opening at the right side of the extrahepatic duct.
The patient was doing well after 6 months of follow-up.
We reported a case of a double common duct with choledocholithiasis and gallstone. This rare anomaly may lead to cholangitis, common bile duct injury during surgery, malignancy occurrence, and should be treated with extreme care.
肝外胆管重复是胆道系统极为罕见的先天性异常。
一名44岁女性，有持续上腹部疼痛和呕吐病史。
磁共振胰胆管造影（MRCP）显示肝内和肝外胆管弥漫性扩张。内镜逆行胰胆管造影（ERCP）显示存在两条肝外胆管，胆总管远端有结石。
ERCP后行腹腔镜胆囊切除术（LC）。术中进行的胆管镜检查显示胆总管重复，胆囊管在肝外胆管右侧开口。
随访6个月后患者情况良好。
我们报告了一例双胆总管合并胆总管结石和胆结石的病例。这种罕见的异常可能导致胆管炎、手术中胆总管损伤、恶性肿瘤发生，应极其谨慎地进行治疗。
