逆行胰胆管造影对梗阻性黄疸的诊断价值

ＥＲＣＰ对梗阻性黄疸的诊断价值。３２例梗阻性黄疸做逆行胰胆管造影（ＥＲＣＰ），与Ｂ超和ＣＴ进行对比，探讨对其定位与病因的诊断价值。结果：恶性胆道梗阻１８例（５６．３％），良性梗阻１４例（４３．７％）。ＥＲＣＰ、Ｂ超及ＣＴ定位诊断率分别为９３．７％、８７．５％与８１．３％，三者比较差异无显著性（Ｐ＞０．０５）；病因诊断率分别为９０．６％、６２．５％与５６．３％，ＥＲＣＰ与Ｂ超和ＣＴ比较差异显著（Ｐ＜０．０５）；误诊率分别为９．４％、９．４％与３．１％，三者比较无显著性差异（Ｐ＞０．０５）。ＥＲＣＰ对梗阻性黄疸的病因诊断率明显优于Ｂ超和ＣＴ，对梗阻性黄疸是一种安全且不可缺少的诊断方法。

DIAGNOSTICVALUEOFENDOSCOPICRETROGRADE HOLANGIOPANCREATOGRAPHY FOR OBSTRUCTIVE JAUNDICE

In Order to evaluate the diagnostic values of the endoscopic retrograte cholangiopan-creatography (ERCP) for obstructive jaundice , we performed the prosedures in 32 cases ,and compared thenwith ultrasound and CT and their diagnostic values were evaluated in regard to location and causes of the obstruction. There were 18 cases of malignant biliary obstruction and 14 cases of benign biliary obstruction. Location of the obstruction judged correctly by ERCP , ultrasound and CT were 93. 7 % , 87. 5 %and 81. 3 %respectively .and there was no different signaicance among them ; Causes of the obstruction confirmed right-ly were 90. 6% ,62. 5%and 56. 3% respectively,the difference was signaficant(P<0. 05). The erroneousdiagnostic rates were 9. 4%,9. 4%and3. 1% separately,and there was no different significance among them (P>0. 05). The results showed that the diagnostic rate of ERCP in the causes of the obstruction had the advantage over ultrasound and CT , Furthermore , it was a safe and also effective diagnostic method in obstructive jaundice.
