彩色多普勒超声对肝门部胆管癌的诊断价值

The value of color Dopper ultrasonography in diagnosing hilar cholangiocarcinoma

目的 评价彩色多普勒超声对肝门部胆管癌的诊断价值。方法 对 42例经手术病理证实的肝门部胆管癌患者进行彩色多普勒超声检查 ,观察肿瘤内供血特点及肿瘤与门静脉之间的关系 ,并对误诊病例进行分析。结果 肝门部胆管癌的彩色血流显示率为 64 .3 % ,彩色血流显示率、门静脉受侵率与肿瘤大小无统计学相关性 ,本组病例超声诊断符合率为 71.4%。肝门部胆管癌需与原发性硬化性胆管炎、Mirizzi综合征、胆囊癌侵犯肝门部胆管、肝细胞癌胆管内癌栓等疾病鉴别。结论 彩色多普勒超声具有符合率高、操作简便、无损伤等特点 ,可评估肝门部胆管癌根治性切除的可能性 ,为临床外科提供了有益的帮助。

Objective To evaluate the value of color Doppler ultrasonography for diagnosing hilar cholangiocarcinoma.Methods Blood flow condition of hilar cholangiocarcinoma and the relationship between tumors and the portal vein were observed by color Doppler ultrasonography in 42 patients who were confirmed in the pathological examination.Results The rate of color blood flow displaying in hilar cholangiocarcinoma was 64.3 %,the diagnostic accuracy was 71.4 % in comparison with surgical and histopathologic findings.It was found that no relationship exists between tumor size and the portal vein involvement as well as the rate of blood flow displaying in the tumor.Hilar cholangiocarcinoma had to be distinguished from primary selerosing cholangitis,Mirizzi syndrome,gallbladder cancer accompanied with hilar bile duct involvement,and hepatocellular carcinoma caused bile duct embolus.Conclusions Color Doppler ultrasonography is a sensitive,convenient and non invasive method and provides important information for preoperative evaluation of resection of hilar cholangiocarcinoma.
