下消化道间叶源性肿瘤CT仿真内镜与病理的对照研究

目的观察下消化道间叶源性肿瘤CT仿真内镜与病理的对照研究．及探讨其可能的作用机理。方法选取来我院消化科就诊的可疑结肠癌患者80例，随机分为实验组和对照组．各40例．实验组给予CT仿真内镜检查及病理检查．对照组给予传统电子肠镜检查及病理检查．所得结果与病理检测结果相对比。结果与病理检测结果相对比．实验组一致率达94．73％．对照组一致率达92．85％。差异无统计学意义（P〉0．05）。结论CT仿真内镜可以很快成像并得出详尽资料，并且癌症诊断的敏感性和特异性大为提高。在临床上，CT仿真内镜与结肠镜有相同功能可替代结肠镜．可以作为电子结肠镜检查不能耐受者或有禁忌症者的重要补充．其应用价值值得近一步深入研究。

Comparative of Gastrointestinal Mesenchymal Tumors of CT Virtual Endoscopy and Pathology

Objective To observe the lower gastrointestinal mesenchymal tumors CT virtual endoscopy and pathology, and to explore its possible mechanism. Methods Select 80 patients suspected colon gastroenterology treat in the hospital gastroenterology department, randomly divided into experimental group and control group, 40 cases in experimental group were given CT virtual endoscopy and pathological check, the control group received conventional colonoscopy and pathological check, and all the results compared with the pathological results. Results Compared with the pathological test results, consistent rate with the experimental group reached 94.73%, the same rate was 92.85% in control group. The difference was not statistically significant （P 〉 0.05）. Conclusions CT virtual endoscopy can quickly image and draw detailed information, and can improve the sensitivity and specificity of cancer diagnosis greatly. Clinically, CT virtual endoscopy have the same function as colonoscopy, can replace colonoscopy, can be important complement of electronic colonoscopy by those who cannot tolerate electronic colonoscopy or have contraindications. Its value is worth taking a step forward in-depth study.
