二维超声和CT诊断阻塞性黄疸的对比研究

Comparison of two dimensional ultrasonography with computed tomography in the diagnosis of obstructive jaundice

目的比较二维超声与CT对阻塞性黄疸的诊断价值。方法回顾性分析82例阻塞性黄疸的二维超声和CT表现,并与手术后病理结果对照分析。梗阻部位分为三段:上段为肝门处胆囊水平以上的肝内外胆管,中段为胰腺以上的胆总管,下段为胰腺及壶腹周围的胆管。结果超声、CT对阻塞性黄疸梗阻部位诊断准确率分别为90.2%和91.5%,对结石及恶性肿瘤诊断准确率分别为94.9%和89.7%、88.9%和91.7%。经X2检验无统计学意义。结论二维超声对结石及大多数恶性肿瘤所致的阻塞性黄疸具有重要的诊断价值。

Objective To compare the diagnostic value of two dimensional uhrasonography and computed tomography（CT） in obstructive jaundice. Methods Retrospective analysis was performed in 82 patients with obstructive jaundice and the results of two dimensional ultrasonography and CT were compared with surgery and pathology. The obstructive level of biliary tract was defineded as pancreatic, periampulla, and at the level of the porta hepatis. Results The level of obstruction was correctly indicated by uhrasonography in 90.2%,and by CT in 91.5% of patients. The cause was correctly indicated by ultrasonography in 94.9% for eholedocholithiasis and 89.7% for malignant tumors, and by CT in 88.9% for choledocholithiasis and 91.7% for malignant tumors. There was no significant difference between ultrasonography. Conclusion Two dimensional ultrasonography is important in the diagnosis of the majority of patients with obstructive jaundice caused by choledocholithiasis and malignant tumors.
