摘要
报告本院近4年收治的、经手术或术中、术后胆道造影证实的肝内结石102例,与术前B超资料进行对比分析,评价B超诊断肝内结石的作用。全组B超检出结石符合率为77.5％,假阴性为17.6％假阳性为4.9％。提示B超作为诊断肝内结石有实用价值。作者还讨论了影响B超正确诊断的一些因素,以及肝胆病变的诊断意义。
One-hundred-and-two cases of intrahepatic bile duct(canoliculi) hospitalized from June, 1982 to March, 1986, were studied. The diagnosis of the patients was confirmed by Type-B ultrasonograph, surgery and cholangiography during operation. The results were compared with the preoperative data of B-us. The positive rate of B-us test for stone was 77.5％, and the false negative rate and false positive rate were 17.6％ and 4.9％, respectively. This investigation demonstrates that this method was useful in the diagnosis of the stones of intrahepatic bile duct. It may also help to discover liver abscess, dilatation of intrahepatic bild duct or intrahepatic spaceoccuping lesion and obstruction of portal vein. etc. Thisethod might also be used as a guide for PTC (D). It had become one of the routine tests for screening patients in hepato-cholo-surgery. The influencing factors of B-us tests are: 1. The experince and carefulness of the technicians. 2. The size of stones and its characteristics on ultrasonic image. 3. No definite relation to the location of stones.
