Clinical and Radiological Considerations for Incorporating Computed Tomographic Colonography into Colorectal Cancer Screening Programs

Flexible fiberoptic colonoscopy or Optical Colonoscopy (OC) has evolved to a routine 20-30 minute procedure. The test requires a pre-procedure preparation consisting of low residue foods and colon cleansing usually with oral, large-volume polyethylene glycol lavage the day prior to the examination. Intravenous sedation, vital sign monitoring, and a 2-3 hour post-procedure recovery are also required. Though OC is considered by most to be the gold standard for viewing the colonic surface, it has limitations. In the largest studies of patients referred for a wide range of suspected colonic problems, failure to view the entire colon occurs in 3-9% and 3% of screening examinations.
