What are the alternative options for a colonoscopy if the patient does not wish to have one?

• A. FIT, CT colonography, colon guard
• B. Colonoscopy every 5 years
• C. Flexible sigmoidoscopy
• D. Barium enema

Answer: (A)

If a patient prefers not to have a colonoscopy, there are alternative colorectal cancer screening options that do not require going inside the colon. Fecal immunochemical testing (FIT) checks for hidden blood in the stool, is simple and noninvasive, and is typically done annually. CT colonography, or virtual colonoscopy, uses CT imaging to visualize the colon; it doesn’t remove polyps, so if a polyp is found, a traditional colonoscopy is still needed for removal. A stool DNA test (Cologuard) looks for DNA markers and blood in stool and is performed at longer intervals; a positive result also requires a follow-up colonoscopy. These options provide screening without an immediate colonoscopy, but each has tradeoffs in sensitivity, frequency, and what happens if results are positive. In contrast, a flexible sigmoidoscopy only examines part of the colon and can miss lesions higher up in the colon, making it not a full substitute for colonoscopy. A barium enema is older and less sensitive, making it a less favored substitute for modern screening.
