Barium Enema - TRG Group - Radiology Radiologists New Zealand

Barium Enema

The barium enema is an imaging test to evaluate the colon and the rectum and may allow imaging of the distal loops of the small bowel.

The barium enema is indicated for the investigation for:


			Pre Examination

	The patient will require an appointment. To ensure the colon is clear the patient will be given a one day laxative preparation. The examination takes 40 - 60 minutes. Female patients – Except in emergency circumstances, this examination is not performed on pregnant women. If your patient may be pregnant please delay the barium enema until after their period or following a negative pregnancy test. Who does the test? A Radiologist and a Radiographer will be in the examination room and will explain the procedure to the patient as the examination proceeds.


			The Examination

	Barium Sulphate is used to coat the bowel wall while the air distends the lumen. The Radiologist observes the filling bowel using fluoroscopy and will position the patient to maximise barium coating and air distribution, necessary to obtain optimal images. Some patients can experience discomfort as the bowel becomes distended with air and the Radiologist may reduce air volume if this is the case. The Radiologist may use an intravenous smooth muscle relaxant to reduce or stop the peristaltic movement. This will lessen the discomfort and also improve visualisation of the bowel. We will advise the patient this may result in temporary impaired vision.


			Post Examination

	After the Radiologist has seen the films the patient is able to go to the toilet. Some patients experience mild colic as the smooth muscle relaxant effect dissipates , but walking around or lying decubitus may assist. It takes several days to fully evacuate the barium. Barium may result in mild constipation so you may wish to advise your patient to increase water consumption and fibre-rich food over the 7 days after the examination. Unless you have requested the images they will be sent to the patient A written report will be available on the day of the examination.
