Endoscopic Ultrasound (cont.)
How is EUS performed?
Upon arrival at the endoscopy center, the nurse or the
doctor will discuss the procedure and answer any questions.
You will then be asked to sign a consent form indicating
you were informed about the procedure, its alternatives,
and its risks. You will undress and put on a hospital gown.
An IV will be placed in a vein and kept open with a slow
drip of IV fluid. This IV will be used to administer the
sedatives or other required medication. Anesthesia is
rarely used. You will then be taken into the procedure room
and, after the administration of the sedation, the
EUS will be carried out. Small electrode patches
will be placed on your skin for the monitoring of your
blood pressure, pulse, and blood oxygen.
Once sleepy, the special endoscope will be inserted and the procedure started.
Because of the sedation, you will only feel minimal
discomfort, if any, during the entire procedure. The physician
will observe the inside of your intestinal tract on
a TV monitor and the ultrasound image on another monitor.
The entire procedure generally takes 30 to 90 minutes
depending on the complexity and whether fine needle aspiration
(FNA) is performed.
After the procedure you will be sleepy for up to one hour and be unable
to drink or walk. Once you are fully awake, the doctor will
discuss with you and, if desired the person with you,
the findings of the procedure. Barring any rare complications, when
you are fully awake, your companion will be
able to take you home where you should rest for the
remainder of the day. Light meals and fluids are allowed.
The bloating which you may feel from the insufflated air
will only be temporary. Should your throat be mildly sore,
for a day or two, salt-water gargles will provide relieve.
You should call your doctor if concerned about your
progress or having severe pain, vomiting, passage or
vomiting of blood, chills or fever. If EUS was
particularly difficult or complicated you may be kept in
the hospital overnight. The endoscopist will discuss this
with you, when you wake up.
