螺旋CT诊断老年大肠癌162例

Diagnostic value of spiral CT for detecting colon carcinoma in senile patients:an analysis of 162 cases

目的:探讨螺旋CT对老年大肠癌的诊断价值.方法:分析经外科手术加病理检查证实的162例老年大肠癌患者的螺旋CT扫描图像,比较螺旋CT检查与结肠镜检查对老年人结肠癌的诊断符合率.结果:CT检查受检率100%,电子肠镜受检率75.3%,40例患者未能完成结肠镜检查,其中包括冠心病、高血压病27例(16.67%),CT检查对老年大肠癌的诊断检出率为80.86%,与电子结肠镜(70.37%)比较有显著提高(P<0.05).结论:螺旋CT检查不仅能发现病变.还能确定病变侵犯范围及转移情况,且无痛苦,对老年患者更安全、方便易行,可作为老年大肠癌诊断的常规手段.

AIM： To evaluate the diagnostic value of spiral CT for detecting colon carcinoma in senile patients. METHODS： One hundred and sixty-two senile colon cancer patients were confirmed by operation and histological examination. All of them received spiral CT or colonoscopy examination. The diagnostic value of spiral CT was compared with that of colonoscopy. RESULTS： All patients received spiral CT scan and 75.3% of the patients received colonoscopy examination. A total of 40 patients did not finish the colonoscopy examination; 27 of these （16.67%） were intolerant of colonoscopy examination because of coronary heart disease and hypertension. The accuracy rate of spiral CT in the diagnosis of colon carcinoma was 80.86%, which was significantly higher than that of colonoscopy examination （70.37%, P 〈 0.05）. CONCLUSION： Spiral CT is a safe, painless and convenient method for detecting colon cancer and its metastasis. It is more suitable for the diagnosis of colon carcinoma in senile patients.
