Double-contrast barium enema
Double-contrast barium enema
Double-contrast barium enema (pronunciation: duh-buhl kon-trast bair-ee-uhm en-uh-muh) is a radiological procedure used to examine the colon and rectum for abnormalities. The term originates from the use of two contrasting materials, barium and air, to visualize the internal structure of the colon and rectum.
Procedure
The procedure involves the administration of a barium sulfate solution into the rectum, followed by air to distend the colon. The barium coats the lining of the colon and rectum, providing a clear silhouette of the area on an X-ray. The air helps to further enhance the images by providing a contrast to the barium.
Uses
Double-contrast barium enema is used to diagnose and monitor various conditions affecting the colon and rectum, such as colorectal cancer, diverticulosis, polyps, and inflammatory bowel disease.
Risks
While generally safe, the procedure may pose certain risks, including bowel perforation, allergic reactions to barium, and radiation exposure. Patients with certain conditions, such as severe colitis or a suspected bowel obstruction, may not be suitable candidates for a double-contrast barium enema.
