目的探讨超声对胆管癌浸润血管的诊断价值,提高手术切除术。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 to improve the surgical resection. Methods A retrospective analysis of 52 cases of cholangiocarcinoma data, focusing on the local tumor and adjacent blood vessels, and set the diagnosis of vascular infiltration of ultrasound. Results Surgical pathology confirmed cholangiocarcinoma 37% (19/52) portal vein invasion. The sensitivity, specificity and diagnostic accuracy were 56% (9/16), 89% (32/36) and 79% (41/52) respectively. The sonographic grade was lower than the pathological grade Accounting for 15% (8/52), higher than grading 6% (3/52); color ultrasound also contributed to the observation and evaluation of hepatic artery branches. Conclusion Ultrasound is a good method to evaluate the extent and extent of vascular invasion around cholangiocarcinoma. It has no trauma and high specificity, and has the value of popularization and application.
