Esophagogastroduodenoscopy (EGD) allows your physician to view the inside of your esophagus (food tube), stomach and duodenum (first portion of the small intestine.) When passed through the mouth, a flexible, rubber-like coated tube, called an endoscope, will provide direct visualization of these areas. The actual procedure lasts only a short time.
This procedure diagnoses the cause of swallowing difficulties, abdominal pain, nausea, causes of upper GI bleeding, and evaluate for reflux, ulcers, tumors and other abnormalities of the upper GI tract.
Your Physician will let you know if you should continue your antacid medications during the test or stop it. Please follow your daily routine, including eating normal meals, but avoid frequent snacking, chewing gum or sucking candies.
What to Expect
You will arrive at the endoscopy center or the hospital after an overnight fast, with a responsible, adult driver. During the procedure, everything will be done to help you be as comfortable as possible. We will carefully monitor your blood pressure, pulse, and oxygen level. The anesthetist will give you IV medication to sedate you during the procedure.
A supportive mouthpiece will be placed to help keep your mouth open during the endoscopy. While you are comfortably sedated, your doctor will gently maneuver the endoscope into position. As the endoscope is slowly and carefully inserted, air is introduced through it to help your doctor see better. During the procedure, you should feel no pain and it will not interfere with your breathing.
Your doctor will use the endoscope to look closely at your upper GI tract. In some cases, it may be necessary to take a sample of tissue, called a biopsy, for later examination under the microscope. This, too, is a painless procedure. In other cases, this endoscope can be used to treat a problem such as active bleeding from an ulcer.
