摘要
目的：分析梗阻性黄疸的ＣＴ表现，探讨螺旋ＣＴ在鉴别诊断中的作用。材料与方法：对经手术、病理证实的梗阻性黄疸６２例进行螺旋ＣＴ、 ＥＲＣＰ＋螺旋ＣＴ联合检查。结果：肝内胆管呈枯枝状扩张多见于胆总管结石（２４／２８）少数可见于肿瘤性病变（３／２８）；呈软藤状扩张，胆管壁见软组织肿块为肿瘤性病变。但不能区分良恶性。病因诊断符合率Ｂ超７３％、螺旋ＣＴ ８７％、ＥＲＣＰ＋螺旋ＣＴ联合检查１００％。结论：梗阻性黄疸良恶性鉴别需结合临床和ＣＴ征象综合分析。螺旋ＣＴ、 ＥＲＣＰ＋螺旋 ＣＴ联合检查是鉴别诊断十分有效的方法。
Purpose: To analyze the CT features of the obstructive jaundice and explore the diagnostic value of Spiral CT. Materials and Methods: 62 cases of obstructive jaundice verified by surgery and pathology were examined by spiral CT and ERCP + spiral CT. Results: Deadwood dilatation of intrahepatic bile ducts usually was seen in choledocholithiasis (24/28), it also could be seen in a few tumorous diseases (3/28). Viny dilatation of intrahepatic bile ducts and mass in bile ducts were seen in tumorous diseases. But we can not differentiate benign and malignant disease only by CT features. The predict value of B - US, Spiral CT and ERCP + Spiral CT for cause of obstruction were 73 %, 87 % and 100 %. Conclusion: Differentiating diagnosis of obstructive jaundice caused by benign or malignant disease need combine clinical materials and CT features. Spiral CT and ERCP + Spiral CT are very effective methods for differentiating diagnosis.
