A test that involves visually examining the lining of the esophagus, stomach, and upper duodenum with a small camera (flexible fiberoptic endoscope) which is inserted down the throat.
You will be given a sedative and an analgesic. 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.
An IV will be inserted to administer medications during the procedure.
You are 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 these organs is examined and biopsies can be obtained through the endoscope. Biopsies are tissue samples that are reviewed under the microscope.
When the area has been viewed and any biopsies taken, the endoscope will be removed.
Food and liquids are restricted until your cough reflex returns.
The test lasts about 15 to 30 minutes.
