| description | Colorectal cancer is an important public health problem that is amenable to prevention and early treatment. Traditional screening techniques - fecal occult blood testing, flexible sigmoidoscopy, barium enema and colonoscopy - each have limitations in terms of diagnostic accuracy, cost and/or patient acceptability. Compliance with recommendations for screening has been poor, in part, because of negative perceptions about the available modalities. Virtual colonoscopy, or computerized tomographic colography, is a minimally invasive technique that safely evaluates the entire colon and does not require sedation. Thorough cleansing as well as immobilization and air insufflation of the colon is crucial to a successful examination. Sensitivity and specificity rates are reasonable, compared with conventional colonoscopy, and it has been shown that the latter technique can be averted in over two-thirds of cases, with few false-negative examinations. Most patients find virtual colonoscopy more acceptable than the conventional technique, and would prefer it if a repeat procedure were warranted. An economic analysis that found that computerized tomographic colography was less cost effective than conventional colonoscopy did not consider the indirect costs of the latter, which is an important limitation. Virtual colonoscopy is a novel radiological technique that may revolutionize screening for colorectal cancer. |
