Barium Enema What Affects the Test
Reasons you may not be able to
have the test or why the results may not be helpful include:
Stool or gas in the colon. Muscle
spasms in the colon wall. Severe ulcerative colitis, toxic megacolon, acute
diverticulitis, or a suspected perforation of the intestine. Pregnancy. Inability to remain still or to cooperate
during the test. Extreme
obesity. A barium swallow test ( upper gastrointestinal series) done within a week before the test. What To Think About If your doctor thinks you have an abdominal mass, other tests
may be needed before or after a barium enema. These include abdominal X-rays,
ultrasound studies, and
computed tomography (CT) scans. If an
upper gastrointestinal series is planned, it should be performed after the
barium enema. The barium swallowed during an upper GI series may take several
days to pass through the intestine and thus can interfere with the results of a
barium enema. A barium enema is not generally used to screen for colon cancer. Other tests are used instead. For more
information, see the topics Stool Tests for Colorectal Cancer,
Colonoscopy, Sigmoidoscopy, and Virtual Colonoscopy. Other Works Consulted
