If, by that time, there is no improvement in constipation, then colonoscopy or barium enema and sigmoidoscopy should be done. When test results were positive, a follow-up colonoscopy was assumed regardless of the polyp size. For this study, the morbidity and mortality rates of colonoscopy were considered as nil. The same point can be made for the subsequent colonoscopies. Cost-effectiveness of colonoscopy in screening for colorectal cancer. In center 2, for example, around 1% of subjects received a radiological examination after sigmoidoscopy, rather than colonoscopy, and the majority exited immediately thereafter. For a subject in center 9, the initial screen led to a radiological examination, colonoscopy, three episodes of surgery, and five outpatient attendances. Three homogenous cost-minimization analyses were identified, which all compare genetic testing with conventional colonoscopy or sigmoidoscopy based on family risk only (3;7;10). Colonoscopy costs have the largest influence on the results. For follow-up of positive cases in the fecal occult blood test, the same recommendation includes colonoscopy as the procedure of choice. On the contrary, changes in the costs of fecal occult blood test kit and colonoscopy had a stronger impact. For one individual in center 7, for example, sigmoidoscopy led directly to surgery, followed by three outpatient attendances, and a follow-up colonoscopy. In severe resistant constipation, the regimen should include a colonic lavage preparation used for colonoscopy. Sigmoidoscopy does not permit examination beyond the left (descending) side of the colon, whereas colonoscopy offers the potential of surveying the entire colon. Lowering colonoscopy costs greatly improved the cost-effectiveness of colonoscopy ever y 10 years. A colonoscopy is also recommended every 10 years. This strategy relies on flexible sigmoidoscopy or colonoscopy. In the case of a positive test, the subject was offered a full colonoscopy. Based on previous reports, we assumed that two deaths would occur for every 10,000 colonoscopies (1). The results of our sensitivity analyses showed the importance of both the cost of the fecal occult blood test and of colonoscopy. As is evident, the expected protocol-initial sigmoidoscopy, repeated if necessary, followed by colonoscopy, repeated if necessary-was adhered to for the vast majority of subjects. Flexible sigmoidoscopy and colonoscopy costs were separately estimated for simple screening procedures versus those with polypectomy/biopsy and pathology (complex). Other payers with a stable patient base and secure long-term financial future may choose colonoscopy, provided they can negotiate the charge down to an acceptable level (25). Thus, other than that for 5-year colonoscopy, cost:effectiveness ratios for all screening options considered in this study can be considered at or below the median.
