Enteroclysis
How the test is performed:
This test is done in a hospital radiology department. A tube is placed through your nose or mouth and manipulated past the stomach into the small intestines. (This may require periodic fluoroscopic examination to determine the correct placement of the tube.) Contrast (barium and/or methylcellulose) is then given through the tube directly into the intestines. The contrast is infused at a controlled rate with a pump. The passage of the barium through the small intestine is monitored on the fluoroscope. Pictures are taken with one in a variety of positions. The test takes up to 6 hours to complete.
How to prepare for the test:
A clear liquid diet is needed for at least 24-hours before the test. Laxatives and/or enemas may be prescribed to ensure that the intestines are clear of any particles that can obstruct the view of the X-rays. The night before the test and the day of the test there should be no smoking. Most oral medications, anticholinergics, and narcotics need to be stopped 24-hours before the test. Remove all jewelry. You must wear a hospital gown. You must sign a consent form.
Infants and children:
The physical and psychological preparation you can provide for this or any test or procedure depends on your child's age, interests, previous experience, and level of trust. For specific information regarding how you can prepare your child, see the following topics as they correspond to your child's age:
How the test will feel:
The X-ray causes no discomfort. However, placement of the tube into the intestines can be uncomfortable.
Why the test is performed:
This test is used to examine the small intestine. It can clarify lesions suspected on upper GI (gastrointestinal) X-ray. It is the best means of demonstrating that the small intestine is normal (when abnormality is suspected) and is useful for identifying the site of partial, intermittent bowel obstructions (the flow rate of barium can cause the intestines to dilate at the obstruction area).
