What the risks are:

The type of radiation exposure is similar to other x-ray procedures. However, the radiation exposure may be greater with this test than with other types of x-rays because of the length of time needed for the fluoroscopic examination. Most experts feel that the risk is low compared with the benefits.

Pregnant women and children are more sensitive to the risks of x-ray radiation. If there is a chance that you are pregnant, you must inform your health care provider, and an appropriate decision will be made regarding the necessity of the procedure.

Rare complications include allergic reactions to medications prescribed for the examination. You should consult with your health care provider to determine any known drug sensitivities. Another very rare complication is possible injury to bowel structures during the study.

Barium may cause constipation. Consult your health care provider if the barium has not passed through your system by 2 or 3 days after the test.

Special considerations:

This test may not be able to see some parts of the intestine because of the position of the tube. An alternative may be an abdominal CT scan.
