Endoscopic Ultrasound

What is an Endoscopic Ultrasound (EUS)?

During a EUS, a microchip camera is installed on the tip of an endoscope; this is
then inserted into the upper or lower digestive tract. This provides images that
are more accurate and more detailed than traditional ultrasound. EUS can also
provide information about the layers of the intestinal wall, as well as adjacent
areas such as lymph nodes and blood vessels. The physician can also take tissue
samples (aka - biopsy) to send out for testing.


EUS has advantages over other diagnostic and therapeutic imaging systems:
  • EUS has very high resolution.
  • EUS combines diagnostic imaging with tissue sampling and directed therapy
    in a single endoscopic modality.
  • EUS is performed in real time (unlike CT-guided biopsies) allowing
    second-to-second adjustment and precise localization of needle
    placement.


How do I get ready for an EUS?

Your stomach and duodenum must be completely empty for the procedure to be thorough
and safe. You will not be able to eat solid food for at least 8 hours prior to the
procedure. You will be able to drink clear liquid up until 3 hours prior and then
you cannot have anything else to drink.


What should I expect during the procedure?

You will be scheduled for the EUS at the hospital as it is not done at our clinic.
You will need to arrive 1 hour prior to your scheduled time so that we can get you
ready. An IV will be administered. This is needed for the anesthetist to administer
a sedative to make you comfortable. Once you are comfortable, the physician will insert
a long flexible scope into your mouth, down to your stomach and into the first part
of the small intestine (duodenum). The procedure takes between 15 to 30 minutes. Once
it is done, you will be taken back to your recovery room. You will begin waking up
very soon. Once you are fully awake, you will be allowed to go home. Remember you
will need someone to drive you home. You will be allowed to resume your regular diet.
We would like for you to rest and relax for the rest of the day. You can resume regular
activities the following day.
