评价超声与腹部CT在胆总管末端癌诊断价值

Ultrasound Evaluation of Common Bile Duct and Abdominal CT in the Diagnosis of Terminal Cancer

目的探讨腹部B超及CT扫描在胆总管末端癌中的诊断价值,指导临床应用。方法回顾性分析我院2000年6月至2011年6月38例住院治疗的胆总管末端癌患者B超与CT检查的情况。结果腹部超声诊断符合率为84.21%,误诊率占15.79%,诊断敏感性为85.29%,特异性为75%;CT扫描诊断符合率达94.74%,误诊率为5.26%,诊断敏感性为97.14%,特异性为66.67%。结论 B超检查与CT扫描检查各有优缺点,两者相结合可以大大提高胆总管末端癌的诊断率。超声及CT诊断医生提高诊断水平有利于减少患者的医疗负担。

Objective To evaluate the abdomen and CT scan in the B--end common bile duct cancer in the diagnosis and guide clinical practice.Methods A retrospective analysis of our hospital in June 2000 - June 2011 38 cases of hospitalized cancer patients with B-end common bile duct and CT inspection.Results Abdominal ultrasound diagnosis rate was 84.21%, accounting for 15.79% misdiagnosis rate,the diagnostic sensitivity of 85.29%,specificity 75%; CT scan diagnosis rate of 94.74% misdiagnosis rate was 5.26%,the diagnostic sensitivity of 97.14 %,a specificity of 66.67%.Conclusion B--ultrasound and CT scans have advantages and disadvantages,a combination of both ends of the common bile duct cancer can greatly improve the diagnostic rate.Ultrasound and CT diagnosis of doctors to improve diagnosis helps to reduce the patient＇s care burden.
