肝门胆管癌,又称Klatskin瘤,是指起源于肝总管、左右肝管及其汇合部的胆道上皮恶性肿瘤。根治性切除是目前治疗肝门胆管癌最有效的手段。该肿瘤位于肝门狭小且管道结构复杂的区域,手术难度大、风险高。近年来,由于影像评估水平和外科手术技术的提高,肝门胆管癌手术切除例数逐年上升。但各治疗中心对于手术入路选择、肝切除范围、淋巴结清扫数量均有不同的标准,且差异较大。有必要探索肝门胆管癌手术质量控制体系。一方面通 Hilar cholangiocarcinoma, also known as Klatskin tumor, refers to the biliary epithelial malignancies that originate in the common hepatic duct, left hepatic duct, and their confluence. Radical resection is currently the most effective treatment of hilar cholangiocarcinoma. The tumor is located in a narrow area of ​​the hepatic portal and the complex structure of the pipeline, the operation is difficult, high risk. In recent years, the number of resections of hilar cholangiocarcinoma has increased year by year due to the improvement of image evaluation and surgical technique. However, the treatment centers for the choice of surgical approach, the scope of liver resection, the number of lymph node dissection have different standards, and the differences are large. It is necessary to explore the hilar cholangiocarcinoma surgical quality control system. On the one hand
