梗阻性黄疸的CT诊断（附40例报告）

目的：研究梗阻性黄疸的良恶性鉴别以及CT的应用价值。材料与方法：回顾性分析40例经临床和手术证实的梗阻性黄疸病例,着重对肝内胆管扩张的不同表现与良恶性梗阻的关系进行探讨。结果：在40例梗阻性黄疸中,28例为良性梗阻,肝内胆管呈“枯树枝”样扩张者26例,占92．8％;12例为恶性梗阻,肝内胆管呈“软藤样”扩张率占100％。结论：“枯树枝”与“指套样”胆扩张虽然不是鉴别良有恶性梗阻的特异现象,但是结合B超、临床以及化验室检查进行综合分析,对提高诊断符合率有着重要意义。

CT Study for to Distinguishing the Obstructive Jaundice (Report 40 Cases)

Purpose:To carry out a research into distinguishing the obstructive jaundice Benign-malignant quality and the appliance value of CT.Materials and Methods:To retrospectively analyze 40 cases of obstructive jaundice proved by operation and clinic,and lay stress on the discussion of the relationship between the different manifestation of the intrahepatic duct's dilatation and obstructive jaundice's benign-malignant quality.Results:among the 40 cases of the obstructive jaundice 28 cases belong to benign obstruction and 26 cases which are 92.85% of them dilate with a "Withered Tree Sign";12 cases among the 40 belong to malignant obstruction and all of these cases dilate with a "Soft Rattan Sign",which are 100%.Conclusion:though they are not the special signs to distinguish the benign-malignant jaundice,linking with the colligate analysis of ultrasound,Clinic and laboratory examining,"Withered Tree Sign"and "Soft Rattan Sign"have a very important meaning of improving the diagnostic coincidence rate
