What to Expect From Your Barium Enema

Introduction

So you're going to have a barium enema! Relax. Though most people think a

barium enema (BE) is an extreme procedure, the truth is that it's not.

Rather, it is a simple fluoroscopic test used to study the large bowel,

or colon. There are few complications, and you'll be able to return home

or to work immediately after the procedure.

What's Involved

The procedure is simplicity itself. First, you lie face-down on the X-ray

table. A technologist then inserts an enema tip into your rectum and

inflates a balloon at the end of the enema tube. This causes the rectum

to distend, making you feel as if you need to defecate. Knowing that this

is a false sensation, you will easily be able to ignore it.

Now the radiologist opens the valve on the tube coming from the barium

bag. With the introduction of the barium inside you, the feeling of

urgency will increase. Continue to ignore it. Using fluoroscopy, the

radiologist can now see the end of the large bowel, where the cramping

occurs. This feeling should ease quickly. If it doesn't, barium may have

to be expelled from the colon and the colon refilled. It may be necessary

to inject glucagon, a bowel relaxant, through a 25 gauge needle into a

vein in your arm.

During this time, feel free to chat with the radiologist and

technologist. Maintain a positive attitude. Tell a few jokes.

The radiologist will take several "spot films" of the fluoroscopy. These

will become a part of your medical record and used to decide if surgery

is necessary. And that's all!

Afterwards

The balloon will be deflated, the enema tip removed, and, after a quick

trip to the bathroom, you may get dressed and resume your normal

activities.

Privacy

Traditionally, such sensitive medical procedures have been held

confidential between patient and doctor. The Freedom of Medical

Information Act of 2014, however, changed all that. You should be aware

that detailed information about your enema will be posted on the world

wide web, including X-rays, photographic stills, and streaming video of

the procedure from start to finish You should be prepared for a certain

amount of razzing (including, in many cases, practical jokes!) from your

family and friends.

In Conclusion ?

But in the final analysis, isn't your health all that really matters?
