The Pros And Cons Of CT Colonoscopy

Optical Colonoscopy was invented in 1969 and has been the gold standard for CRC screening ever since (Wolf, 1989). The gold standard is its 90% sensitivity for adenoma 5mm, and 97% sensitivity for advanced adenoma based on employing CTC as a standard. Colonoscopy is an invasive imaging procedure which visually examines the whole colon and permits the gastroenterologist to perform biopsies on suspicious polyps. A few additional disadvantages to this procedure besides the invasiveness are the prep procedures to cleanse the bowel, the mandatory use of sedatives, patients must have a companion to transport them home, time-consuming, expensive, perforation of the bowel, and bleeding. However, this test is repeated every ten years (Patel & Ahnen, 2015).
Its specificity is 86-95% and the test is repeated every five years. Disadvantages to using CTC is that it may not detect small polyps sizes such as
Most patients are unaware of the choice to undergo the CTC procedure thus do not ask for them. It should become common practice for physicians to offer this to their patients. They only offer CTC for screening CRC in frail patients. Providing educational materials and administering patient preference Likert questionnaire to patients will assess the state of mind of their patients. Although the June 2016 recommendation by the USPSTF does not have a snapshot of CTC as a screening method. It is still listed as evidence is not sufficient but it does not advertise that with a recommendation of I as seen in the 2008 snapshot. The USPSTF now believes that any CRC screening test that encourages patients to participate is worth it. (USPSTF,
