BARIUM ENEMA - AN X-RAY STUDY OF YOUR COLON

 

This fact sheet is designed to give you general information about your exam. Any individual problems or questions should be directed to your physician.

 

Barium Enema:

The purpose of this exam is to study your colon (large intestine) in a controlled manner with barium (a white liquid that permits the visualization of the colon under fluoroscopy). The colon’s function is to assist in the absorption of digested food.

 

Preparation for the Exam:

1. Barium Enema is a scheduled exam and must be proceeded with a 2-3 day preparation diet, to include oral and/or rectal laxatives. This diet usually includes a low fat diet 2-3 days prior to exam and a clear liquid diet the day before the exam, then nothing by mouth after midnight the morning of the exam. Failure to follow the preparation instructions closely may reduce the diagnostic value of your examination and make a thorough evaluation of your colon very difficult. Follow your local radiology department’s instructions because each hospital’s preparation instructions may vary slightly.

2. If at any time during the preparation of the exam you feel ill, please notify your physician and call the Diagnostic Imaging unit for assistance or further instructions.

 

The X Ray Itself:

1. A radiologist will perform the exam using a machine called a fluoroscope. The radiologist will insert a rectal tube that allows the barium to flow into your colon in the same manner any enema would be given. Once the enema tip is in place the barium is released to fill the colon. Once the colon is filled, the barium is drained to just leave the colon coated with a thin layer of barium. At this point, the colon is distended with air to enhance the visualization of the colon.

2. You may feel discomfort or some cramping at the time air is added to the colon. Slow, deep breaths will help you relax. During the exam, the machine and x-ray table will move and you will be asked to roll in various positions. After the radiologist has completed the fluoroscopic exam, the technician will take additional radiographs to complete the exam. After the films have been reviewed by the radiologist, you will be sent to the bathroom and allowed to expel the barium and air.

3. The exam will last approximately 45 to 60 minutes.

4. After the exam is completed you may return to your normal diet. You also should be able to return to duty/work with little or no discomfort. The barium should pass normally from your colon. Your physician may order a laxative to ease the passage. If you do not have a bowel movement within three days after the procedure, please inform your physician.

 

Interpretation of Results:

The radiologist will interpret the results of the procedure and will report the information to your physician, who in turn, will discuss the report with you.
