0 a medical examination of the colon (= the lower part of the tube that takes solid waste out of your body)
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).
