An endoscopic ultrasound is a thin, flexible tube placed through your mouth into your stomach. It bounces high energy sound waves off of the organs to create a picture of the organs and help find the area(s) of concern.

How to Prepare for This Test

• 8 hours before: Do not eat or drink anything. You may take medications with sips of water the morning of your procedure.
• Please bring your CT scan films to your appointment (if you have one).

What to Expect
This procedure is typically performed with anesthesia or sedation. This will be discussed when you are contacted by a nurse for your pre-assessment evaluation. If it is determined that sedation or anesthesia is necessary depending on your diagnosis and/or physician preference, a driver must accompany you and stay in the waiting area during your procedure. Click here to read more about what to expect in the GI Lab at Vanderbilt.
