EGD

Upper GI endoscopy, sometimes called EGD, is a visual examination of the upper intestinal tract using a lighted, flexible endoscope.  It allows the physician to visualize the esophagus, the stomach and the entrance into the small intestine known as the duodenum.  The flexible endoscope can be directed and moved around the many bends in the gastrointestinal tract.  The endoscope has a tiny, optically sensitive computer chip at the end.  Electronic signals are then transmitted up the scope to the computer which then displays the image on a large video screen. An open channel in these scopes allows other instruments to be passed through in order to take tissue samples, remove polyps and perform other exams. 

An EGD is a valuable tool in the prevention and early detection of upper intestinal disease or abnormalities such as:

  • Ulcers (which can develop in the esophagus, stomach or duodenum)
  • Tumors of the stomach or esophagus
  • Difficulty in swallowing
  • Upper abdominal pain or indigestion
  • Heartburn or acid reflux
  • Anemia (diminished red blood cell count)
  • Intestinal bleeding

Preparing for the exam

The preparation for the exam varies based on physician preference.  To obtain the full benefits of the exam, the stomach needs to be completely empty.  The physician will instruct you on when to begin fasting, specific dietary restrictions, and instructions prior to the exam.  The physician will also advise you on the use of regular medications during the preparation time.  It is very important that the preparation be completed as prescribed.  This will allow for clear visualization of the upper GI tract. 

The day of the procedure

  • Bathe or shower on the morning of your exam to minimize the risk of infection.
  • You may brush your teeth and rinse, but do not swallow any water.
  • Wear clean, loose, comfortable clothing and low-heeled shoes to the surgical center.
  • Do not smoke prior to your exam.  Ask your doctor when you need to discontinue smoking.
  • Do not wear jewelry (including earrings and body piercings), or bring valuables with you.
  • Bring your insurance card(s) with you.
  • Bring your reading glasses with you.
  • Bring a complete list of all of your medications, including dosages.
  • You cannot drive following the procedure, and need a responsible adult to drive you home.  For your safety, this policy is strictly adhered to.  You may take a taxi only if accompanied by a responsible adult.
  • You can expect to be at the surgical center for a minimum of two hours. 
  • Following the procedure, when at home, you may eat and drink normally unless otherwise instructed by your physician.
