An upper endoscopy (EGD) is performed to examine the upper gastrointestinal tract, including the esophagus, stomach, and first portion of the small intestine. This procedure is used to determine the cause of gastrointestinal disorders and symptoms such as heartburn, Barrett’s esophagus, abdominal pain, or difficulty swallowing.
After completing the necessary procedure preparations, you will be placed on your left side on the examining table. An IV will be started and intravenous sedation will be given. A lighted, flexible endoscope will be inserted into your throat to conduct the examination. A plastic mouth guard is usually used to protect the endoscope and your teeth. A tiny camera at the tip of the endoscope will transmit images to a monitor for your physician to view. If the physician finds anything unusual during the exam, such as an ulcer or inflamed tissue, a biopsy may be performed to remove a small piece of the affected tissue to be sent to a lab for testing.
