Barium enema (children)
What is a barium enema examination?
A barium enema is a rectal injection of barium contrast that coats the lining of the colon and rectum. X-ray films are obtained to detect tumours, polyps, haemorrhoids, diverticula (pouches within the colon), or any other disease or changes in the colon. The procedure takes less than one hour.
In children, a water-soluble contrast is used instead of barium. This will cause less constipation and discomfort afterwards.
What preparation is needed?
The colon (sometimes called the large bowel) needs to be empty and clean for adults. For children, it depends on the age and what preparation is required. Please turn the page for the preparation instructions.
What happens during the examination?
Your child should be undressed completely. A gown will be available to put on. A lubricated soft catheter will be inserted into the rectum. The radiologist will use the x-ray equipment and watch as the barium or water-soluble fluid flows into the colon. In some cases, a little bit of air will also be pumped into the colon to distend it.
After a series of X-rays, the catheter will be removed, and the barium or fluid will be evacuated.
What are the possible complications?
The enema is a relatively safe procedure. Rare complications include bowel perforation, barium impaction, water intoxication, allergic reactions, or cardiac arrhythmias.
What happens after the procedure?
After this procedure, your child may resume normal activities.
What about the result?
Once the examination is completed, the radiologist will study the X-rays and compare them to any previous X-rays of the same area. A typed report of the findings will be completed and forwarded to your Physician. Please contact your physician for the results.
