摘要
目的:评价16层螺旋CT在结肠癌性肠梗阻中的应用价值。方法:回顾性分析经手术病理证实的34例结肠癌性肠梗阻的CT表现,并与临床手术及病理结果对照。结果:MSCT对引起梗阻的肿瘤定位、定性准确率分别为100%、97%,对其TNM分期的准确率为69.7%、78.8%、100%,对其浆膜外侵犯的敏感性和特异性分别为77.8%、33.3%,对淋巴结转移的敏感性和特异性分别为80.9%、75%。结论:MSCT对引起肠梗阻的结肠癌的定位、定性准确性高,对结肠癌TNM分期判断准确性高,对评估肿瘤的可切除性及制定治疗方案具有重要意义。
Objective：To evaluate the value of MSCT in the diagnosis of colon cancerous obstruction. Methods： MSCT features of 34 cases of colon cancerous obstruction were analyzed and compared with the results of surgical findings and pathology retrospectively. Resuits：The location and qualitative accuracy of MSCT was 100%, 97% respectively. The accuracy for TNM preoperative staging was 69.7%, 78.8%, 100%. The sensitivity and specificity of invading tunica serosa was 77.8%, 33.3%. The sensitivity and specificity of lymph node metastasis was 80.9%, 75%. Conclusion： MSCT has high accuracy in location and qualitative and TNM preoperative staging of colon cancerous obstruction. It has important significance in assessment of tumor respectability preoperatively and protocol making.
