Esophagogastroduodenoscopy – The Procedure


is a diagnostic procedure which screens the upper digestive tract for the growth for foreign bodies. In this procedure, a small camera (flexible endoscope) is inserted down the throat to examine the lining of the esophagus, stomach, and upper duodenum. It is also called as upper endoscopy. In this article, we discuss more about the procedure.

The procedure:

You are asked to fast for overnight or at least for 6 to 12 hours before the test. You need to sign on an informed consent form and tell your doctor about all the medications that you are using. You will be asked to stop taking blood-thinning medications such as aspirin for several days before the procedure.

You will be given an analgesic or painkiller before starting this procedure. A local anesthetic is sprayed into your mouth so that you may not feel any pain. This also suppresses the need to cough or gag during the procedure. You are asked to remove dentures. Your mouth is covered with mouth guard to protect your teeth.

  • You are asked to lie on your left side.
  • A endoscope is put in and advanced. Air is introduced through the endoscope to see the enhanced view.
  • Tissue samples are taken by the instruments provided at the end of endoscope.
  • Treatments are also done such are widening a narrowed area of the esophagus.
  • After completing the test, you need to restrict intake of food and liquids until gag reflex returns.
  • It takes about 5 to 20 minutes to complete the process.

How you feel after the procedure:

This procedure is a safe one with almost negligible side effects. Sometimes local anaesthesia can make swallowing difficult, but it wears off shortly after the procedure. You may also feel a sensation of gas or bloating and the movement of the scope in the abdomen. This goes off in a short period of time.
