Upper GI Endoscopy


What is an upper GI endoscopy?

An upper GI endoscopy or EGD (esophagogastroduodenoscopy) is a procedure to diagnose and treat problems in your upper GI (gastrointestinal) tract.
The upper GI tract includes your food pipe (esophagus), stomach, and the first part of your small intestine (the duodenum).
This procedure is done using a long, flexible tube called an endoscope. The tube has a tiny light and video camera on one end. The tube is put into your mouth and throat. Then it is slowly pushed through your esophagus and stomach, and into your duodenum. Video images from the tube are seen on a monitor.

Small tools may also be inserted into the endoscope. These tools can be used to:

  • • Take tissue samples for a biopsy
  • • Remove things such as food that may be stuck in the upper GI tract
  • • Inject air or fluid
  • • Stop bleeding
  • • Do procedures such as endoscopic surgery, laser therapy, or open (dilate) a narrowed area

What happens during an upper GI endoscopy?

You may have an upper GI endoscopy as an outpatient or as part of your stay in a hospital. The way the test is done may vary depending on your condition and your healthcare provider’s practices.

Generally, an upper GI endoscopy follows this process:

1. You will be asked to remove any clothing, jewelry, or other objects that may interfere with the procedure. If you wear false teeth (dentures), you will be asked to remove them until the test is over.
2. If you are asked to remove clothing, you will be given a gown to wear.
3. An IV (intravenous) line will be started in your arm or hand. A medicine to relax you (a sedative) will be injected into the IV.
4. Your heart rate, blood pressure, respiratory rate, and oxygen level will be checked during the procedure.
5. You will lie on your left side on the X-ray table with your head bent forward.
6. Numbing medicine may be sprayed into the back of your throat. This will stop you from gagging as the tube is passed down your throat into your stomach. The spray may have a bitter taste to it. Holding your breath while your provider sprays your throat may decrease the taste.
7. You will not be able to swallow the saliva that may collect in your mouth during the procedure. This happens because the tube is in your throat. The saliva will be suctioned from your mouth from time to time.
8. A mouth guard will be placed in your mouth. This will keep you from biting down on the tube. It will also protect your teeth.
9. Once your throat is numbed and the sedative has relaxed you, your provider will put the tube in your mouth and throat. He or she will guide the tube down your esophagus, through your stomach, and into your duodenum.
10. You may feel some pressure or swelling as the tube moves along. If needed, samples of fluid or tissue can be taken at any time during the test. Other procedures, such as removing a blockage, may be done while the tube is in place.
11. After the exam and procedures are done, the tube will be taken out.

What happens after an upper GI endoscopy?

After the procedure, you will be taken to the recovery room to be watched. Once your blood pressure, pulse, and breathing are stable and you are awake and alert, you will be taken to your hospital room. Or you may be discharged to your home. If you are going home, someone must drive you.

You will not be allowed to eat or drink anything until your gag reflex returns. This is to prevent you from choking. You may have a sore throat and pain for a few days when you swallow. This is normal.

You may feel gassy after the procedure. You may go back to your normal diet and activities, unless you have other instructions.

Call your healthcare provider if you have any of the following:

Your healthcare provider may give you other instructions, depending on your situation.
