This article presents information on a study related to an analysis of air contrast barium enema, computed tomographic colonography, and colonoscopy. 614 patients with 1 positive test result for fecal occult blood, 1 episode of bright-red blood per rectum in the previous 3 months, iron-deficiency anemia, or a family history of colon cancer or adenoma were observed for the said study. Exclusion criteria included active gastrointestinal hemorrhage and serious medical illness. In patients at high risk for colonic neoplasia, colonoscopy was more sensitive and specific than air-contrast barium enema or computed tomographic colonography for detecting large colonic polyps.
