Abstract    Objective    To explore the feasibility and outcome of resection of the ventral segment of the hepatic portal，for the treatment of complicated intrahepatic and extrahepatic bile duct stones with portal stenosis. Methods    To analyze the cilinical data such as stone clearance rate，complications，and follow-up results of 16 cases，with complicated intrahepatic and extrahepatic bile duct stones with portal stenosis who treated with resection of the ventral segment of the hepatic portal from January 2015 to August 2019 in Hunan Provincial People's Hospital retrospectively. Results    Among the 16 patients，7 cases received the resection of partial IVb segment of the liver; 3 cases received the resection of partial V segment of the liver; 4 cases received the resection of partial IVb and V segment of the liver; 2 cases received the resection of IVb and partial V segment of the liver. The operation was successful without death in hospital and serious complications. The postoperative follow-up time was 6~57 months，and all of patients had an excellent evaluation of therapeutic efficacy. There was no stenosis in primary and secondary bile ducts by postoperative cholangiography，but 7 cases exist stenosis in tertiary bile ducts with a few retained bile duct stone. 5 cases were not completely removed after postoperative choledochofiberscopy. Close follow-up showed no obvious clinical symptoms. Conclusion    The resection of the ventral segment of the hepatic portal is a safe and feasible method for the treatment of complicated intrahepatic and extrahepatic cholelithiasis with hilar stenosis，and it can fully expose the hilar bile duct.

摘要： 目的    探讨肝门腹侧肝脏切除手术处理复杂肝胆管结石并肝门狭窄的可行性和疗效。方法    回顾性分析2015年1月至2019年8月湖南省人民医院肝胆外科采用肝门腹侧肝脏切除手术治疗的16例复杂肝内胆管结石并肝门狭窄病例的临床资料，随访观察结石清除及术后并发症情况。结果    16例病人中4b段部分切除7例，5段部分切除3例，4b段+5段部分切除4例，部分4b段+5段切除2例。手术均顺利完成，无住院死亡，无严重并发症。术后随访时间6~57个月。所有病人疗效评估均为优。术后胆道造影检查均未见1、2级胆管狭窄，7例有3级胆管狭窄，发现少量结石残留，术后经胆道镜取净结石，5例未能取尽，密切随访观察，无明显临床症状。结论    肝门腹侧肝脏切除手术可充分显露肝门胆管，更有效地处理复杂肝内外胆管结石并肝门狭窄，手术安全可行且能建立通畅的胆肠引流途径。
