Barium
Studies (Fluoroscopy)
Because
the digestive tract cannot be accurately investigated by plain x-rays, it
is usually studied using a barium preparation that helps outline the gut.
The
Barium Meal
It
is the study of the upper part of the digestive tract, mainly the stomach
and adjacent segments.
Preparation
You
must not eat or drink anything after midnight on the morning before the
x-rays.
Avoid
smoking during this period.
The
Examination
-
You
may be given an injection just before the examination.
-
You
may be given baking soda crystals that will form gas in your stomach.
-
A
cup containing liquid barium will be given to you to drink.
-
The
doctor will then proceed with the examination.
After
the examination
You
will be asked to wait while the radiologist reviews the films to make sure
they contain all the necessary information. Occasionally more films may be
required.
Barium
Enema
This
is a specialized examination to study your large intestine in a controlled
manner with barium
Preparation
-
A
low-residue diet is required before the examination.
-
Avoid
vegetables, cereals, milk or creamy products, fruits, oily / fatty food.
-
On
the days before the examination you will be required to take laxatives
that will help clean your bowels.
-
No
solid food should be taken after 12 mid-night, on the day preceding the examination but carry on taking fluids until 2 hours before
procedure.
The
Examination
The
radiologist, a doctor who specializes in x-ray examinations and
interpretation, will perform the exam using a machine called a
fluoroscope. A rectal tube will be inserted, to allow the barium to flow
into your colon in the same manner any enema would be given.
During
the exam, the x-ray machine and table will move and you will be asked to
roll around so that x-rays are taken in various positions.
Your
colon will also be inflated with air, administered through the same rectal
tube. This may cause certain discomfort, but is essential as it provides
for better visualization.
Several
x-ray films will be produced during the examination in different
positions, to help the radiologist reach a diagnosis.
After
the radiologist has completed the fluoroscopic exam, the technologist will
take additional radiographs to complete the exam.
After
the examination
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.
After
the examination, you should drink plenty of fluids to avoid constipation.
After
the examination is completed you will return to your normal diet. The
barium should pass normally from your colon.
