 We compared barium (Ba) enema with colonoscopy for the screening examination of colon cancer. Compared to the total colonoscopy, the sensitivity of Ba enema was about 90% for the lesion more than 5 mm in size. But, Ba enema was not regarded as a sufficient examination for the flat lesion in the right side hemicolon, because even a sm cancer more than 10 mm in size may not be detected by Ba enema. The sensitivity and specificity of Ba enema for the small lesion less than 5 mm in size were not satisfactory for the screening examination. In conclusion, total colonoscopy is necessary for the routine screening examination of colon cancer. If Ba enema was chosen as a screening examination, shooting and reading of the film should be carefully done in awareness of blind spots of the examination.
