A barium enema is a radiographic (X-ray) examination of the lower gastrointestinal (GI) tract. The large intestine, including the rectum, is made visible on X-ray film by filling the colon with a liquid suspension called barium sulfate (barium) or water soluble contrast agent. This study is used for colon cancer screening, evaluation of stricture (narrowing to the hole in the bowel), leak at the site of surgery. Barium enema is used to evaluate ulcerative colitis, crohn’s disease, irritable bowel syndrome, obstructions, and growth. With this study, a catheter is needed to prevent the contrast agent from leaking out through the anal canal. Since the Cephus Catheter is the only double balloon colorectal catheter available for use on patients, it will provide an optimal outcome.
