Abstract: 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(x2 =14.72,P＜ 0.05);sensitivity was 95.6％ (65/68) in CTVE and 97.7％ (42/43) in electronic eolonoscopy(x2=0.003,P ＞ 0.05);endoscopy coincidence rate with pathologic classification was 95.4％ (62/65) in C-TVE and 95.2％(40/42) in electronic colonoscopy.Conclusions CT virtual endoscopy may be one of examination methods in elderly patients with colon cancer.
