梗阻性黄疸的CT表现及诊断价值

CT manifestation of obstructive jaundice and its diagnostic value

目的 提高CT对梗阻性黄疸诊断重要性的认识。方法 回顾性分析了72例经手术和病理证实的梗阻性黄疸病例的CT表现,并与B超诊断进行了比较。结果 本组引起梗阻性黄疸性的疾病,分别为胆管结石、胆管癌、胰头癌、胆囊癌及肝癌。CT的正确率为91.7％,超声的正确率84.7％,CT和超声作为互补的检查方法,其正确率可达94.4％。结论 CT能很好地显示胆管的扩张,梗阻段胆管的改变及其对周围软组织的浸润和转移情况。CT和超声互补,可作为梗阻性黄疽的病因诊断较为有价值的可靠方法。

[Abstract] Objective To make a further emphasis on the diagnostic significance of obstructive jaundice. To make a further understanding of the diagnosing of obstructive jaundice. Methods CT findings of 72 cases with surgically and pathologically proved obstructive jaundice were analyzed retrospectively, and a comparison with B-ultrasonography was made. Results The causes of obstructive jaundice in this study included cholelithes, cholangiocarcinoma, carcinoma of head of pancreas, carcinoma of gallbladder and hepatoma. The diagnostic accuracies of CT and ultrasonography were 91.7% and 84.7%, respectively. When coupled CT with ultrasound, the diagnostic accuracy could reach to 94.4%. Conclusion CT scan can well show cholangiectasis, the outline of obstructed bile duct and the invasion to the surrounding tissue. As complementary to each other, CT and ultrasound together can provide reliable cetiologic diagnosis for obstructive jaundice.
