脂餐后肌注654—2对胆管扩张超声诊断的研究

Study of ultrasonographic Diagnosis of Bile Duct Dilataion by Injection of 654-2 after Fat Intake

为提高超声显像对胆管扩张病因诊断符合率，对40例胆管扩张者行服餐后肌注654－2进行B超观察。结果显示肝外胆管显示长度增加，内径明显增宽，同时胆管内透声亦明显改善。其病变显示率从37．5％提高到90％，病因诊断符合率达87．5％。说明本方法为提高胆管扩张病因诊断率提供了无创伤的手段。

To improve the accuracy rate of ultrasonographic diagnosis of the causes of bile duct dilatation.Forty subjects of bile duct dilatation intramuscular injected 654 - 2 after fat intake were studied by ultrasonography. The results showed the increased length and the inside diameter of extrahepatic bile duct and the obvious improvement of ultrasound pentration. The demenstration rate of bile duct dilatation increased from 35.7% to 90%,and the diagnosis accuray rate was 87. 5%. The is method is a noninvasive one to increase the accuracy rate of diagnosis in the causes of bile duct dilatation.
