Upper GI Endoscopy (EGD)
An upper gastrointestinal endoscopy, or esophagogastroduodenoscopy (EGD), lets your doctor look at the interior lining of your esophagus, your stomach, and the first part of your small intestine (duodenum) through an endoscope—a thin, flexible tube with its own light that is used to view the body’s internal organs and tissues.
Using the endoscope, your doctor can look for ulcers, inflammation, tumors, infection or bleeding. Tissue samples can be collected (biopsy), polyps can be removed, and bleeding can be treated through the endoscope. Endoscopy can reveal problems that do not show up on X-ray tests, and it can sometimes eliminate the need for exploratory surgery.
During a Upper GI Endoscopy
The test usually takes 30 to 45 minutes, but it may take longer, depending upon what is found and what is done during the test. After the test, you will be observed for 1 to 2 hours until the sedating medications wear off.
After a Upper GI Endoscopy
Your doctor will tell you the results of your test after it is completed. If a biopsy was done to take tissue samples, you must wait several days for the results.
After the medication has worn off, your throat may be slightly sore, and you might feel bloated from the air that was pumped into your abdomen during the procedure. When you are fully recovered, you can go home. You shouldn’t drive or operate machinery for 12 hours after the procedure. Your doctor will tell you when you can resume your usual diet, medications and activities. Do not drink alcohol for 12 to 24 hours after the test.
Possible Complications of an Upper GI Endoscopy
Complications from gastrointestinal endoscopy are rare. However, you should discuss your specific risks with your doctor. Risks include:
- A slight risk of puncturing your esophagus, stomach or upper small intestine (duodenum); surgery may be needed to repair this
- Bleeding from the procedure itself or any tissue samples (biopsy) that are taken
- Irregular heartbeat during the procedure; this nearly always subsides on its own without treatment
- Greater risk if you have serious heart disease, are an older adult or are frail or weak
