Which procedure is often recommended for patients with suspected colon polyps?

Flexible sigmoidoscopy is the recommended procedure for patients with suspected colon polyps because it allows direct visualization of the rectum and the lower part of the colon (sigmoid colon). During this procedure, a flexible tube with a light and camera is inserted into the rectum, enabling the healthcare provider to examine the lining of the colon for abnormalities, including polyps.

If polyps are observed during the sigmoidoscopy, they can often be removed at that time for biopsy, allowing for both diagnosis and treatment in a single visit. This procedure is less invasive than a full colonoscopy and typically requires less preparation, making it a practical choice for initial evaluation of polyps.

Other imaging options like MRI or X-ray are not as effective for directly assessing the mucosal surface of the colon and identifying polyps. Similarly, stool testing can be useful for screening purposes or detecting blood in the stool but does not provide visual confirmation of polyps or the ability to remove them. Thus, flexible sigmoidoscopy is the superior method for evaluating suspected colon polyps.
