What is EGD?
EGD (esophagogastroduodenoscopy) is a minimally-invasive procedure used to examine the upper part of the digestive track including the esophagus, stomach, and duodenum. A thin, flexible tube outfitted with a small camera is inserted down the patient's throat and through the upper digestive track, transmitting a clear view of the relevant digestive organs to a nearby monitor. If needed, small tissue samples may be extracted for biopsy. Still photos can also be taken for further examination and diagnosis.
What is EGD used for?
EGD is commonly used to investigate potential causes of:
- upper gastrointestinal (GI) bleeding
- dysphagia (swallowing difficulties)
- abdominal pain
- chronic heartburn
EGD can detect the presence of:
- other abnormalities along the upper GI track.
EGD is also a therapeutic tool useful for removing polyps, treating ulcers, controlling upper GI bleeding, or dilating (stretching out) narrowed areas along the digestive track.
What are the possible complications?
Complications of the procedure are generally limited to perforation (a puncture or small hole) or bleeding if a biopsy is performed, both of which are very rare. Reaction to the sedatives or medication used is also a possibility, so it is important to discuss your prior medical history with your doctor.
How to prepare for the procedure?
In order to prepare for this test, you will most likely need to fast overnight (six to 12 hours) in order to empty your stomach. Your physician will want to know any medications you may be taking, as you may need to stop them prior to the test. It is also important to discuss your medical history and any allergies with the examiner prior to the start of the procedure.
What to expect during the procedure?
In preparation for the insertion of the endoscopy tube, you will receive a topical anesthetic to numb the throat. It may also require intravenous sedatives or pain medication; general anesthesia may be used in extreme cases of anxiety or discomfort.
During the procedure itself, you will lie on your left side while the tube is gradually advanced over the tongue, down the esophagus, and through the stomach to the duodenum. You may experience some mild discomfort including stimulation of the gagging reflex and the sensation of gas. The test takes anywhere from five to 20 minutes.
What to expect after the procedure?
When the test is finished, you will be monitored as the effects of any medications you were given wear off. Side effects may include a sore throat or bloated feeling, both of which are mild and short-lived. You are generally required to have someone else drive you home from the test, and are allowed to resume a normal diet within a few hours of release.
