EGD (Esophagogastroduodenoscopy) is a procedure that examines the esophagus, stomach and first portion of the duodenum (small intestine) using a lighted flexible tube that is inserted into the mouth and advanced to the small intestine. EGD is a diagnostic and/or therapeutic procedure used to help in the diagnosis or treatment of stomach/duodenal ulcers, inflammation, gastroesophageal reflux disease (GERD), cancer, or dysphagia (swallowing problems) and other problems in the upper gastrointestinal tract. 

How to Prepare for EGD

  • No food or liquids (this includes water) minimally 6 hours prior to the procedure.
  • You may also have diet and/or medication restrictions the week prior to the exam. Please refer to your physician for detailed instructions. 
  • 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.

What to Expect Once You Arrive for EGD

  • 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 15-20 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) or remove polyps (growths on the lining of the stomach).

What to Expect After EGD

  • 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.
  • Patients are provided discharge instructions to take home.
