An upper endoscopy, also known as esophagogastroduodenoscopy (EGD), is a medical procedure used to examine the upper digestive tract, which includes the esophagus, stomach, and the first part of the small intestine (duodenum). It is performed on an outpatient basis under sedation using a flexible, thin tube called an endoscope, with a light and a camera attached to it. The endoscope is inserted through the mouth and passed down the throat to visually examine the inner lining of these organs.

During an upper endoscopy, your gastroenterologist can closely examine the mucous membranes and walls of the esophagus, stomach, and duodenum to look for abnormalities, such as inflammation, ulcers, tumors, polyps, or other structural issues. This procedure can help diagnose gastrointestinal conditions and disorders, including difficulty swallowing, gastroesophageal reflux disease (GERD), heartburn, gastritis, peptic ulcers (stomach ulcers), celiac disease, and more.

In addition to visualization, an upper endoscopy allows us to take tissue samples (biopsies) for further laboratory analysis if necessary. It can also be used to treat certain conditions, such as removing polyps, dilating narrow areas (strictures), and controlling bleeding through the use of specialized instruments that can be passed through the endoscope.

We start the procedure with an IV to help you feel drowsy and comfortable. We also spray a numbing medication into the back of your throat to facilitate the insertion of the tube. A mouthguard is placed in your mouth to protect your teeth and keep you from biting on the tube. Once your throat is numb, we insert the endoscope down your esophagus, through your stomach, and into your duodenum. 

You should feel no pain during the procedure, which generally takes 10-15 minutes. Once we remove the endoscope, you will be moved to the recovery room, where our staff will monitor your pulse, blood pressure, and breathing. Once the medication has worn off, we will share the results and provide post-procedure instructions so you can return to your normal routine.
