双胆总管是胆道畸形中罕见的先天性异常。该异常与胆道梗阻有关,具有重要的临床意义。此外,如果两个胆总管中的一个在手术中被误认为是胆囊管,有可能发生结石残留和胆管损伤。这里,我们报告1例胆总管双变异(Vb型)伴胆总管结石。一名82岁妇女因上腹部轻度疼痛并伴有呕吐3天而入院。磁共振成像提示胆总管结石,胆总管变异和中度胆道扩张。腹腔镜联合胆道镜取石术用于胆总管切开取石术。在操作过程中,左、右胆总管切开取石术,所有胆结石都通过胆道镜切除.病人术后恢复良好,在撰写本文时,未观察到胆石症复发。
Double common bile duct is a rare congenital anomaly among biliary anomalies. The anomaly has an important clinical implication because of its association with biliary tract obstruction. In addition, if one of the two common bile ducts is mistaken for the cystic duct during surgery, residual stones and bile duct injury are likely to occur. Here, we report a case of double choledochal variation (Type Vb) with choledochal calculi. An 82-year-old woman was admitted to the hospital due to mild pain in the upper abdomen accompanied by vomiting for 3 days. Magnetic resonance imaging suggested common bile duct lithiasis, variation of the common bile duct and moderate biliary tract dilation. Laparoscopy combined with choledochoscopic lithotomy was performed for choledocholithotomy. During the operation, left and right choledocholithotomy was performed, and all the gallstones were removed via choledochoscope. The patient\'s post-operative recovery was good, and no recurrence of cholelith had been observed at the time of writing.
