Esophagogastroduodenoscopy (EGD)

Esophagogastroduodenoscopy (EGD) is a test to examine the lining of the esophagus (the tube that connects your throat to your stomach), stomach and first part of the small intestine. It is done with a small camera (flexible endoscope) that is inserted thru your mouth and goes down your throat.

Because you'll receive a sedative and a painkiller (analgesic), you should feel no pain, and you won't remember the procedure. A local anesthetic may be sprayed into your mouth to prevent you from coughing or gagging when the endoscope is inserted. A mouth guard will be inserted to protect your teeth and the endoscope. Dentures must be removed.

In most cases, a needle (IV) will be inserted into a vein in your arm to give you medications during the procedure. You'll be instructed to lie on your left side.

After the sedatives have taken effect:

  • The doctor inserts the endoscope through your mouth into the esophagus, the stomach and duodenum. Air is put into the endoscope to make it easier for the doctor to see.
  • The doctor examines the lining of the esophagus, stomach and upper duodenum on a screen as he or she controls the endoscope. Biopsies can be taken through the endoscope. Biopsies are tissue samples that are looked at under the microscope.
  • Different treatments may be performed, such as stretching or widening a narrowed area of the esophagus.

The test lasts approximately five to 20 minutes.

After completion of the test, you won't be able to have foods and liquids until your gag reflex returns to ensure that you don't choke.
