目的评价超声、CT对恶性胆道梗阻性疾病的临床诊断价值,探讨肝内、外恶性胆道梗阻的超声、CT诊断与鉴别诊断。方法回顾性分析58例恶性胆道梗阻患者的超声、CT表现,并与手术病理及临床结果对照。结果本组58例患者恶性胆道梗阻超声定位诊断准确率为95%,定性诊断率为90%;CT定位诊断准确率为91%,定性诊断率为83%。结论超声对恶性胆道梗阻定性、定位诊断正确率优于CT,是一种有效的非侵袭性检查方法。
Objective To evaluate the value of ultrasound and CT in the diagnosis of malignant biliary obstructive diseases and to explore the diagnosis and differential diagnosis of intrahepatic and extrahepatic biliary obstructions by ultrasonography and CT. Methods A retrospective analysis of 58 cases of malignant biliary obstruction in patients with ultrasound, CT findings, and surgical pathology and clinical results. Results The diagnostic accuracy rate of malignant biliary obstruction in 58 patients was 95%. The diagnostic accuracy rate was 90%. The diagnostic accuracy rate of CT localization was 91% and the qualitative diagnosis rate was 83%. Conclusion The diagnostic accuracy of ultrasound in the diagnosis of malignant biliary obstruction is better than that of CT, which is an effective noninvasive examination method.
