Barium Enema
The barium enema is a radiological procedure used to examine the lining of the colon and rectum. Also known as low intestinal series.
Barium refers to barium sulfate, a chalky chemical that appears white on radiographs. Enema means any liquid introduced into the rectum through the anus. After the barium sulfate reaches the intestines, take a series of radiographs. Through these films, the liquid white neighborhood allows certain abnormalities in the intestinal mucosa from being obscure. During this procedure, you can also introduce air into the intestines to help increase the contour of the bowel wall.
The test takes about 45 minutes. It is an outpatient procedure. Although radiographs are painless, the enema may cause mild discomfort and some gases.
For what it is used?
The barium enema is used to diagnose tumors of the colon and rectum. Also used to search for polyps (abnormal growths in the colon), diverticula and other problems. It is now used less frequently because there are new studies such as CT virtual colonoscopy (a type of enema that uses a CT scan), which provides more information.
