Endoscopic Ultrasonography (EUS) is a procedure that joins traditional endoscopic procedures with ultrasound technology. This allows the examination of tissue and structures not only within the digestive tract, pancreas, gallbladder, but also surrounding it.

EUS Upper Procedure Preparation

  • No food or liquids (this includes water) minimally 6 hours prior to the procedure.
  • You may also have diet and/or medication restrictions (especially aspirin and/or other anti-inflammatory products).
  • If you are on Coumadin or other blood thinners, please contact your primary care physician (PCP). Notify the gastroenterologist if your PCP feels you need to continue on the Coumadin.  
  • Plan to take the day off from work for the exam.
  • Plan to have someone you know drive you home. Since the procedure is usually performed with intravenous sedation, you will be instructed to not drive a car or return to work until the next day.
  • Contact the physician and inform him or her of any special needs, medical conditions, latex allergy or current medications you are taking.
  • The GI Lab staff will attempt to contact you the evening before your procedure to answer any questions you may have.

Pre-EUS Upper Procedure Expectations

  • You may be expected to arrive 30 minutes prior to your scheduled exam time.
  • You may have an intravenous line placed, since the procedure is usually performed with intravenous sedation.
  • You will be asked if there is a responsible person to drive you home after the exam.
  • The procedure usually takes about 60-90 minutes.
  • During the exam, there is often a feeling of pressure in the abdominal area.
  • Your physician may give you medication to help you relax and better tolerate the exam.
  • Patients usually lie on their left side.
  • During the procedure the physician may take biopsies (small tissue samples), remove polyps (growths on the lining of the stomach), or aspirate cysts or growths.

Post-EUS Upper Procedure Preparation

  • After the procedure is completed you will recover for about 30 to 45 minutes.
  • You may experience a sore throat after the procedure.
  • Once you have met the discharge criteria, the physician will discuss with you the preliminary findings.
  • After the recovery period patients are able to go home and usually eat right away.
  • Diet and/or medication restrictions may be given to certain patients depending on the findings of the exam.
  • If a cyst is aspirated, the patient will be prescribed antibiotics. 
  • Patients are provided discharge instructions to take home.
