Gastroscopy (EGD) is a commonly performed routine test. This test may be advised if you have symptoms such as recurring indigestion, recurring heartburn, pains in the upper abdomen, repeated vomiting, difficulty swallowing, or other symptoms thought to be coming from the upper gut. The sort of conditions which can be confirmed (or ruled out) include:
When you arrive at the endoscopy unit, you will be registered and asked to sign the consent form. The test can be done without sedation, but most people prefer to have sedation during the procedure. A topical anesthetic agent will be used to numb the throat and reduce gagging. You will be drowsy but conscious during the gastroscopy. The drowsiness can last for up to a couple of hours. If you have sedation, you must have a responsible adult to drive you home or accompany you in a taxi. We do not allow you to go home by public transport or to take a taxi on your own. You cannot drive, operate dangerous machinery or go back to work until the next day. You should avoid making important decisions or drinking alcohol during this period.
The gastroscope is passed through the mouth. A mouthguard is used to protect your teeth. Dentures should be removed. While gastroscopy can be uncomfortable, it is not usually painful. Some people experience a desire to cough or gag when the scope is passed into the esophagus.
During the procedure, small samples (biopsies) may be taken. These will be sent to the laboratory for examination by the pathologist. The testing may include looking for a bacteria known as Helicobacter pylori which are associated with an increased risk of ulcers.
