Fairly high risk: CT scans are NOT good tools for looking inside the bowel. Endoscopy is the preferred tool, but a sigmoidoscopy, at its best, misses looking at half the colon. A look to merely 35 cm has missed about 85-90% of the colon. The usual method to evaluate the colon is a complete colonoscopy.
