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) which is inserted down the throat.

You will be given a sedative and a painkiller (analgesic). You should feel no pain and not 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 will be instructed to lie on your left side.

After the sedatives have taken effect:

  • The endoscope is inserted through the esophagus (food pipe) to the stomach and duodenum. Air is put into the endoscope to make it easier for the doctor to see.
  • The lining of the esophagus, stomach, and upper duodenum is examined. Biopsies can be taken through the endoscope. Biopsies are tissue samples that are looked at under the microscope.
  • Different treatments may be done, such as stretching or widening a narrowed area of the esophagus.

After the test is finished, you will not be able to have foods and liquids until your gag reflex returns (so you don't choke).

The test lasts about 5 to 20 minutes.
