目的：探讨ＣＴ对梗阻性黄疸病因的诊断价值。方法：回顾性分析了１２４例经手术和病理证实的梗阻性黄疸病例的ＣＴ征象，并与Ｂ超诊断进行了对比。结果：１．ＣＴ诊断梗阻性黄疸病因的符合率９６％ ，高于Ｂ超的７９％ 。２．梗阻性黄疸病因最多为结石（７０ 例），其次为肝脏、胆道肿瘤（４８例）。３．ＣＴ对硬化性胆管炎等少见病有３例漏误诊。结论：ＣＴ能明确显示扩张的胆管、胆管梗阻段的征象及对周围软组织的浸润和转移。应作为梗阻性黄疸诊断的首选方法，在疑难病例中应结合其他影像学方法诊断。
Objective: To investigate the diagnostic value of CT on the etiology of obstructive jaundice. Methods: CT findings of 124 cases of obstructive jaundice confirmed by surgery and pathology were retrospectively analyzed and compared with the diagnosis of B-ultrasound. Results: 1. The coincidence rate of CT diagnosis of obstructive jaundice was 96%, which was higher than 79% of B ultrasound. 2. The causes of obstructive jaundice were mostly stones (70 cases), followed by liver and biliary tumors (48 cases). 3. CT sclerosing cholangitis and other rare diseases, 3 cases misdiagnosis. Conclusion: CT can clearly show the expansion of bile duct, bile duct obstruction signs and the surrounding soft tissue infiltration and metastasis. Should be used as the preferred method of diagnosis of obstructive jaundice in difficult cases should be combined with other imaging methods of diagnosis.
