Getting Ready for an Endoscopic Ultrasound
What is an Endoscopic Ultrasound?
An endoscopic ultrasound (EUS) is an exam that involves passing a tube with an ultrasound tip through your mouth into your esophagus, stomach, and upper part of the small bowel. The ultrasound allows the doctor to look at the depth of the lining of these organs. The ultrasound can also be used to see other organs such as the liver and pancreas. The doctor can detect problems and perform biopsies during this exam.
Important – Read 1 week in advance.
Procedure may be cancelled if instructions are not followed
1. 7 days before, you should stop taking the blood thinner Effient® (prasugrel).
2. 5 days before, you should stop taking:
- Blood thinners, such as Coumadin® (warfarin) or Plavix® (clopidogrel).
3. 2 days before, you should stop taking the blood thinner Pradaxa® (dabigatran).
Blood thinning pills should never be stopped without discussing this with the doctor who prescribes it for you. The doctor will give you instructions on how to safely do this. Contact us if you have questions.
4. Diabetic medicines (oral and insulin) will need to be adjusted for the time you’re not eating as normal. Please discuss this with your primary doctor.
5. You must have an adult to drive you home or your exam will be cancelled. You may take a cab or bus home only if you have a responsible adult with you other than the driver.
6. Plan ahead. For your exam you will be given sedatives which can greatly affect your judgment. On the day of your exam, you will not be able to drive or return to work.
7. Our staff will need to review your health history, prior surgeries, allergies, and medicines taken. Please bring this information with you.
8. If you use CPAP or BiPAP for sleep apnea, please bring it with you. We will need your machine in order to sedate you safely.
9. If you have an implanted pacemaker or defibrillator, we will need specific information about it before your procedure day. If you haven't already given us this information, please call us during business hours (8:00 AM to 5:00 PM, Monday through Friday) at (608) 263-8097. Ask to speak to the Procedure Coordinator
Day of the EUS
- No solid food, milk, or dairy products until after your exam.
- Do not take liquid antacids before your exam.
- You may drink clear liquids until 4 hours before you arrive (i.e., water, apple juice, soda, Gatorade®). Avoid red liquids. You must stop the liquids for sedation to be given safely.
- Take your normal medicines with a small sip of clear liquid up to 1 hour before you arrive.. Do not take the pills and supplements mentioned under “Getting Ready.”
- Follow the arrival and registration instructions in your cover letter. If you are delayed, call us at (608) 263-8094 to let us know you are going to be late. If you are over 30 minutes late, we may have to cancel and reschedule. We do our best to stay on time.
- Plan to be with us about 2-3 hours. Your driver will need to be available in our waiting room or by phone.
The Endoscopic Ultrasound
A nurse will review your health history and place an IV. The IV is used to give you medicines which make you feel drowsy and relaxed. The procedure will take 1 – 2 hours. You will then go to our Recovery Room for about one hour. Your driver may sit with you there. Once awake, you will be given something to drink.
Your doctor will discuss results with you before discharge. You and the doctor who referred you will receive a copy of the report.
After the EUS
- Do not return to work.
- Do not drive.
- Do not use hazardous machinery.
- Do not make any important decisions.
- Plan to rest.
- Do not drink alcohol.
You should be able to resume normal daily tasks on the day after your exam.
You may have a mild sore throat – salt water gargles should help.
You may have some gas pains from the air used to distend your stomach. When you belch you will expel the air and relieve any discomfort.
