scheduled exam time.
PREP:
In order to do an x-ray examination of your colon, it is essential that
your bowel be empty. You will be given an E-Z EM prep kit with step by
step instructions. You are not to eat anything after midnight. If
you think you are pregnant, please tell your doctor. This procedure may be
harmful to the fetus.
PURPOSE:
A colon exam involves filling the large intestine or colon with a barium
substance; this allows the colon to be visualized by x-ray.
WHAT TO EXPECT:
You will put on a hospital gown and be brought to an x-ray exam room. The
room will be darkened during the test. You will be asked to lie on your
left side, while an x-ray technologist gently inserts the tip of a
well-lubricated enema tube into your rectum. A small balloon at the end of
the tube is inflated to help keep the barium inside. A barium solution
will then be given through this tube into the colon. You will be asked to
retain the barium solution while your x-rays are being taken. After the
required x-rays are taken, the barium will be allowed to drain out of your
colon, the enema tube will be removed, and you will be taken to the
bathroom to expel any remaining barium. When you are done in the bathroom
another x-ray will be taken.
POST EXAM
INFORMATION: When you have your first few bowel movements you
will notice barium in your stool. This is normal. If you become
constipated, or begin bleeding from your rectum, notify your nurse or
physician. Your physician will discuss the results of this test with you.
TIME FRAME:
Approximately 1 hour.
