Both the ACG and ASGE recommend and endorse colonoscopy as the preferred prevention strategy for colorectal cancer because of its ability to view the entire colon and remove potentially precancerous polyps. Flexible sigmoidoscopy, on the other hand, offers only a limited view of the lower left side of the colon.
Delbert Chumley, MD, and M. Brian Fennerty, MD, presidents of the ACG and ASGE respectively, add that screening colonoscopy is one of the few preventive services that contributes to cost-savings in the healthcare system.
