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 investigate the diagnostic value of ultrasound in infiltrating blood vessels of cholangiocarcinoma and improve the resection rate. Methods: Retrospective analysis of 52 cases of cholangiocarcinoma, focused on the relationship between local tumors and adjacent blood vessels, and set diagnostic indicators of ultrasound on vascular invasion. RESULTS: Surgical pathology confirmed 37% (19/52) portal vein invasion of cholangiocarcinoma. The sensitivity, specificity, and diagnostic accuracy of echocardiographic evaluation of cholangiocarcinoma invasion were 56% (9/16), 89% (32/36), and 79% (41/52), respectively; ultrasound grading was lower than pathological grading 15% (8/52) was higher than 6% (3/52) of pathological grade; color ultrasound also contributed to the observation and evaluation of hepatic artery branches. Conclusion: Ultrasound is a good method to evaluate the extent of vascular invasion around the bile duct cancer. It is non-invasive and highly specific. It has the value of popularization and application.
