Pre Approval Testing
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.
You will be given a sedative and an analgesic. A local anesthetic will 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 gag reflex has been suppressed by the anesthetic, the endoscope will be advanced through the esophagus 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. The test lasts about 5 to 20 minutes.
