CT仿真内镜与电子肠镜对老年结肠癌诊断价值的比较研究

Comparative study of diagnostic value of computed tomographic virtual endoscopy versus electronic colonoscopy for colon cancer in elderly patients

目的对比研究CT仿真内镜与电子肠镜对老年结肠癌患者的诊断价值。方法69例老年结肠癌患者术前均行CT仿真内镜与电子结肠镜检查，比较两种检查方法的成功率，敏感度及病理分型的符合率。结果对老年结肠癌患者CT仿真内镜检查的成功率98．6％（68／69），电子肠镜检查成功率62．3％（43／69），差异有统计学意义（χ2=14．72，P〈0．05）；对老年结肠癌患者CT仿真内镜检查的敏感度95．6％（65／68），电子肠镜检查的敏感度97．7％（42／43），差异无统计学意义（χ2=0．003，P〉0．05）；对老年结肠癌患者CT仿真内镜检查的病理分型符合率95．4％（62／65），电子肠镜检查的病理分型符合率95．2％。结论CT结肠仿真内镜可作为老年结肠癌患者的检查方洪岁一．

Objective To study the diagnostic value of computed tomographic virtual endoscopy versus electronic colonoscopy for colon cancer in elderly patients. Methods The 69 cases of elderly patients with colon cancer received CTVE and electronic colonoscopy before surgery to compare achievement rates, sensitivities, and endoscopy coincidence rate with pathologic classification between the two methods. Results For a definite diagnosis of colon cancer in elderly patients, achievement ratio was 98.6 % （ 68/69 ） in CTVE and 62.3 % （43/69） in electronic colonoscopy （χ2 = 14.72, P 〈0.05） ;sensitivity was 95.6% （65/68） in CTVE and 97.7% （42/43） in electronic colonoscopy（χ2 = 0. 003, P 〈 0.05 ） ; endoscopy coincidence rate with C-TVE and 95.2 % （40/42） in electronic colonoscopy pathologic classification was 95.4% （62/65） in Conclusions CT virtual endoscopy may be one of examination methods in elderly patients with colon cancer
