Upper Gastrointestinal Endoscopy


Upper gastrointestinal endoscopy is also called esophagogastroduodenoscopy (EGD). A scope (thin, flexible tube with a light) is used to examine the walls of your upper gastrointestinal tract (GIT). The upper GIT includes the esophagus, stomach, and duodenum (first part of the small intestine). An EGD is used to look for problems, such as bleeding, polyps, ulcers, or infection.


You have the right to help plan your care. Learn about your health condition and how it may be treated. Discuss treatment options with your caregivers to decide what care you want to receive. You always have the right to refuse treatment.


You may bleed more than expected or get an infection. You may have a slow heartbeat or low blood pressure. This can cause sweating and fainting. Your GIT may be punctured or torn during the procedure. This is because of increased pressure as the scope and air are passing through. Without this procedure, your signs and symptoms may get worse. Caregivers may not be able to find problems and treat your condition. You may have problems swallowing, eating, or digesting food.


Before your procedure:

  • Informed consent is a legal document that explains the tests, treatments, or procedures that you may need. Informed consent means you understand what will be done and can make decisions about what you want. You give your permission when you sign the consent form. You can have someone sign this form for you if you are not able to sign it. You have the right to understand your medical care in words you know. Before you sign the consent form, understand the risks and benefits of what will be done. Make sure all your questions are answered.
  • An IV is a small tube placed in your vein that is used to give you medicine or liquids.

During your procedure:

  • Your caregiver will give you medicine to help you relax and make you drowsy. It will also help prevent coughing or gagging. Your caregiver will gently insert the endoscope through your mouth and down into your esophagus, stomach, and duodenum. You may be asked to swallow to help move the scope down your throat. Your caregiver will watch the scope on a monitor as it moves down your GIT. He will take pictures with the scope. He may inject air or water into your GIT so he can see clearly. Suction will be used to remove air, water, blood, or other liquid.
  • Your caregiver may inject fluid under tissues that look suspicious or use dye to mark them. This is done so the tissues are easier to remove. He may take tissue samples and send them to the lab for tests. He may remove foreign objects, tumors, or polyps that may be blocking your esophagus, stomach, or duodenum. Your caregiver may also insert tools with the scope to treat bleeding or place a stent (tube). When the procedure is finished, the endoscope will be slowly removed and your mouth will be wiped with gauze.

After your procedure:

You will be taken to a room to rest until you are fully awake. Caregivers will monitor you closely for any problems. You may burp or pass gas from air that is in your stomach and bowel. Do not get out of bed until your caregiver says it is okay. When your caregiver sees that you are okay, you will be allowed to go home. If you are staying in the hospital, you will be taken to your hospital room.

  • Pain medicine: Caregivers may give you medicine to take away or decrease your pain. Do not wait until the pain is severe to ask for your medicine. Pain medicine can make you dizzy or sleepy. Prevent falls by calling a caregiver when you want to get out of bed or if you need help.
  • Antibiotics: This medicine is given to help treat or prevent an infection caused by bacteria.
