In this examination it is administered through a tube to outline the small bowel.

You will be asked to eat or drink nothing for 6 hours prior to the time of the examination. You may take your usual medication.

The Examination
A soft, plastic tube is passed in through the nose and down the throat into the stomach and into the small bowel. A local anaesthetic spray into the nose or throat may allow a smooth and more comfortable passage of the tube.

Barium liquid is then put down the tube and a series of X-rays is taken. Sometimes the barium is slow to pass into the small bowel and the procedure may take up to one hour.

After the Test
The radiologist can review the films and send a report to your doctor.

If a local anaesthetic spray has been used, you should not eat or drink for two hours after the X-ray.

A laxative is given following the procedure to allow the barium to be passed out of the bowel more easily, and your bowel motions will be white for the next few days.
