目的探讨肝内胆管细胞癌淋巴结转移的CT特征。方法选择于2013年12月~2015年12月在我院治疗的肝内胆管细胞癌淋巴结转移患者86例,总结其螺旋CT表现,主要是观察转移淋巴结的大小、分布、密度,ICC转移淋巴结分组及淋巴结转移与肿瘤分化程度的关系。结果 186例患者中,共发生淋巴结转移42例,占48.8%;242例肝内胆肝细胞癌淋巴结转移率由高到低依次为:肝十二指肠韧带淋巴结转移36例,占85.7%,贲门-胃小弯-胃左淋巴结组19例,占45.2%,胰头后方淋巴结组18例,占42.8%等;3在发生淋巴结转移的42例患者中,组织学分型为高-中分化癌的有33例,低分化型的有9例。结论螺旋CT能够清晰诊断肝内胆管细胞癌淋巴结转移情况,为临床治疗提供可靠的参考,值得推广应用。 Objective To investigate the CT features of intrahepatic cholangiocarcinoma lymph node metastasis. Methods Eighty-six patients with intrahepatic cholangiocarcinoma who had lymph node metastasis who were treated in our hospital from December 2013 to December 2015 were retrospectively analyzed. The spiral CT findings were mainly observed in the size, distribution, density, lymph node metastasis of ICC And lymph node metastasis and the degree of tumor differentiation. Results Of the 186 patients, there were 42 cases of lymph node metastasis, accounting for 48.8%. The lymph node metastasis rate of 242 cases of intrahepatic cholangiocarcinoma from high to low were as follows: 36 cases of hepatoduodenal lymph node metastasis (85.7% 19 cases (45.2%) were gastric cardia-gastric curvature-stomach left lymph node group, 18 cases were posterior pancreatic lymph node group (42.8%). 3 Among the 42 cases with lymph node metastasis, the histological type was high-moderately differentiated There are 33 cases, poorly differentiated in 9 cases. Conclusion Spiral CT can clearly diagnose lymphatic metastasis of intrahepatic cholangiocarcinoma and provide a reliable reference for clinical treatment, which is worthy of popularization and application.
