EGD - esophagogastroduodenoscopy Health Article

Definition

Esophagogastroduodenoscopy (EGD) is an examination of the lining of the esophagus, stomach, and upper duodenum with a small camera (flexible endoscope) which is inserted down the throat.

Alternative Names

Esophagogastroduodenoscopy; Upper endoscopy; Gastroscopy

How the test is performed

You will be given a sedative and an analgesic (painkiller). A local anesthetic may be sprayed into your mouth to suppress the need to cough or gag 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, an intravenous line will be inserted into your arm to administer medications during the procedure.

You will be instructed to lie on your left side.

After the sedatives have taken effect, the endoscope will be advanced through the esophagus (food pipe) to the stomach and duodenum. Air will be introduced through the endoscope to enhance viewing. The lining of the esophagus, stomach, and upper duodenum is examined, and biopsies can be obtained through the endoscope. Biopsies are tissue samples that are reviewed under the microscope.

After the test is completed, food and liquids will be restricted until your gag reflex returns (so you don't choke).

The test lasts about 5 to 20 minutes.

How to prepare for the test

Fasting is required overnight (6 to 12 hours before the test). An informed consent form must be signed. You may be told to stop aspirin and other blood-thinning medications for several days before the test.
