Objective To investigate the clinical value of ultrasound in the diagnosis of cancer thrombi in the bile duct. Methods Ultrasonic appearances of 23 patients with malignant biliary obstruction and cancer thrombi in the bile duct confirmed pathologically and radiographically were analyzed retrospectively. Results Ultrasonography showed,the obstruction position of cancer thrombi located the intrahepatic bile duct in 1 case,portal area in 17 cases, extrahepatic bile duct in 5 cases. The sonographic appearance of thrombi in biliary duct displayed hypoechoic filling in 20 cases and low ultrasonic transmission in 3 cases. The biliary duct wall was destroyed in 3 cases. Conclusions Ultrasonography could show the obstructive position cancer thrombi in biliary duct, and to indicate the extent of adhesions between bile duct wall and the thrombi.%目的 探讨超声在胆道癌栓诊断中的临床应用价值.方法 收集23例经手术病理和临床治疗证实的恶性梗阻性黄疸伴胆道癌栓的患者资料,回顾性分析其胆道癌栓的声像图表现.结果 23例超声显示胆管癌栓阻塞部位在肝内胆管部1例,肝门部17例,肝外胆管部5例.20例患者超声表现为胆道内低回声不同程度的填充,3例显示胆道内透声差;3例显示胆管壁受破坏.结论 超声不仅能提示胆管梗阻部位,也可以检出胆道内癌栓,且一定程度上可以提示胆管壁与癌栓的粘连程度,对临床治疗方式的选择具有较高的参考价值.
