摘要
目的探讨肝外胆管癌术前应用超声检查的临床价值。方法对经手术病理证实的73例肝外胆管癌病人的超声与临床手术病理结果进行对照,分析其二维声像图特征。结果超声诊断肝外胆管癌符合66例占90.4%,其中肝门部胆管癌31例;胆总管癌35例。结论超声能显示胆管癌的形态、大小及周围淋巴结肿大等异常声像图。应用二次谐波成像技术能判断肿瘤对周围组织是否浸润,对治疗方案的制定有一定意义。
Objective To explore the clinical value of ultrasound on preoperative diagnosis of extrahepatic cholangiocarcinoma. Methods The ultrasound results of 73 cases with extrahepatic cholangiocarcinoma confirmed by pathology were compared with clinical pathological characteristics and the characteristics of 2 - D images were analyzed. Results Accordance rate of ultrasound was 90.4% （66/73）, of which 91.2% （31/34） in hilus hepatis, 89.7% （35/39） in common bile duct. Conclusion The ultrasound can reveal unusual images of cholangiocarinoma, including its shape, size and enlarged perilymph nodes. Preoperative examination of extrahepatic cholangiocarcinoma by second harmonic imaging technology can reveal small lesion in bile duct, and determine tumor infiltration to adjacent tissues. It has importamt value in making treatment plan.
