梗阻性黄疸的超声检查与定位诊断

Ultrasound diagnosis of obstructive jaundice and location of their obstructive site

目的 提高超声对梗阻性黄疸的诊断技术水平。方法 对近两年中有超声检查及手术结果的77例进行分析,其中胆管结石35例,胆管蛔虫2例,胆管癌10例,壶腹癌7例,胰头癌10例,其它13例。结果 通过对超声图像特征的分析与手术病理对照,梗阻性黄疸病因诊断准确率97％,定位诊断准确率98.7％。结论 认为超声对梗阻性黄疸病因的诊断及病变定位诊断具有很高的临床诊断价值。定位诊断准确性与检查者操作手法及经验密切相关。

purpose To improve the ultrasound technique for obstructive jaundice diagnosis. Methods In this paper 77 cases who had the results of ultrasonography and operation were analysed. There were 35 cases of choledocholithisis, 2 cases of bile duct ascariesis, 10 cases of cholan-giocarcinoma, 7 cases of carcinoma of ampulla vater, 10 cases of cnacer in head of pancreata and 13 cases of others. Results The analysis of ultra-sonographic characteristics and the comparation with operation results show that the accurate rate of ultrasonography is 97 % , obstructive site location is 98.7 % . Conclusions So the application of ultrasonography to obstructive jaundice diagnosis and obstructive site diagnosis has great clinical value . The accuracy of obstructive site location is relevant to technique and experience of the operators.
