Upper GI Endoscopy with Dr. Amontree

Upper GI Endoscopy, or Esophagogastroduodenoscopy (eh-SAH-fuhgoh-GAS-troh-doo-AH-duh-NAN-skuh-pee) is an important test for many types of digestive problems. Here’s useful information that will answer many of your questions and help you prepare. Let Dr. Amontree or our team know if you have any further questions or concerns.

What is this test and why do I need it?
Upper endoscopy enables Dr. Amontree to look inside the esophagus, stomach, and duodenum (first part of the small intestine). The procedure might be used to discover the reason for swallowing difficulties, nausea, vomiting, reflux, bleeding, indigestion, abdominal pain, or chest pain.

For the procedure you will swallow a thin, flexible, lighted tube called an endoscope (EN - doh - skope). Right before the procedure, Dr. Amontree will spray your throat with a numbing agent that may help prevent gagging. You may also receive pain medicine and a sedative to help you relax during the exam. The endoscope transmits an image of the inside of the esophagus, stomach, and duodenum, so Dr. Amontree can carefully examine the lining of these organs. The scope also blows air into the stomach: this expands the folds of tissue and makes it easier to examine the stomach.


With the Upper GI Endoscopy test, Dr. Amontree can see abnormalities, like ulcers, through the endoscope that don't show up well on x-rays. Instruments can also be inserted through the scope to remove samples of tissue (biopsy) for further tests.

Possible complications of upper endoscopy include bleeding and puncture of the stomach lining. However, such complications are rare. Most people will probably have nothing more than a mild sore throat after the procedure.

The procedure takes 20 to 30 minutes. Because you will be sedated, you will need to rest for 1 to 3 hours until the medication wears off.

Your stomach must be empty, so do not eat or drink anything after midnight. If you must take prescription medication, use only small sips of water. Do not take antacids.

What Will Happen
Dr. Amontree will talk with you about the procedure and make sure all your questions are answered. Please tell us if you have had any other endoscopic examinations, or any allergies or bad reactions to medications. You will be asked to sign a consent form, giving your permission for the examination. You will need to put on a hospital gown, and remove your eyeglasses, contact lenses and dentures.

You may be given medication by injection through a vein to make you sleepy and relaxed. While in a comfortable position on your left side, the doctor will pass the endoscope through you mouth, and down your throat. A guard will be placed to protect you teeth. The instrument will not interfere with your breathing, nor cause any pain. The examination takes 10 to 30 minutes.

You will remain in the Center until the main effects of any medication wear off. Your throat may feel numb and slightly sore. You should not attempt to eat or drink until your swallowing reflex is normal (at least 1 hour). After this you may return to your regular diet unless otherwise instructed. You may feel slightly bloated, due to the air, which has been injected through the endoscope. This will quickly pass.

If you have had a sedative injection, a companion must be available to drive you home. For the remainder of the day you should not drive a car, operate machinery, or make important decisions, as the sedation impairs you reflexes and judgment.

Endoscopy can result in complications such as reactions to medication, perforation of the intestine, and bleeding. These complications are very rare (less than 1 in 1000 examinations), but may require urgent treatment and even an operation. The possibility of complication is greater when the endoscope is used to apply treatment. Be sure to inform us if you have pain, black tarry stools, or troublesome vomiting in the hours or days after endoscopy.
