摘　　要：目的：探讨超声对胆管癌浸润血管的诊断价值，提高手术切除率。方法：回顾性分析了５２例胆管癌资料，重点观察局部肿瘤与相邻血管关系，并设定了超声对血管浸润的诊断指标。结果：手术病理证实胆管癌３７％（１９／５２）门脉受侵。超声评价胆管癌门脉受侵的敏感性、特异性及诊断正确率分别为５６％（９／１６）、８９％（３２／３６）和７９％（４１／５２）；超声分级低于病理分级者占１５％（８／５２），高于病理分级者占６％（３／５２）；彩色超声亦有助于肝动脉分支的观察评价。结论：超声是一种较好的评价胆管癌周围血管受侵及其程度的方法，其无创伤及特异性高，有推广应用价值。Objective:To evaluate the diagnostic value of ultrasound for vascular involvement in cholangiocarcinoma.Methods:Fifty two patients with cholangiocarcinoma were studied retrospectively.Results:Portal vein infiltration was found by opeation and pathology in 37% of cases.The sensitivity,specificity and accuracy of ultrasound in evaluating vascular involvement were 79%,97% and 91%,respectively,of 52 cases,the degree of vascular infiltration as compared with operation and patologic findings was 79% correct,15% underestimated and 6% overestimated.Conclusion:Ultrasound appears to be useful modality in the assessment of vascular involvement of cholangiocarcinoma.
