Colonoscopy (cont.)

Considerations for the Future

In an effort to develop a safe, efficient, and comfortable screening exam for colorectal cancer, the development of a test called virtual colonoscopy has received increasing interest. This technique involves similar preparation of the bowel and computerized manipulation of a series of abdominal and pelvic CT scan images. Initial studies appear promising. More studies are required, however, to prove that this procedure is just as accurate.

The American Cancer Society recently revised its recommendations for colorectal screening to include an emphasis on the examination of the entire colon. Despite this, 80% of American adults do not undergo screening. Currently, colonoscopy is the only technique available to directly look at, biopsy, and potentially treat digestive diseases of the large intestine.
