Upper Endoscopy, or Esophagogastroduodenoscopy (EGD)

What is an Upper Endoscopy, or EGD?

An upper endoscopy, or EGD, allows your physician to examine the upper part of your gastrointestinal tract, which includes the esophagus, stomach and duodenum (first part of the small intestine). An upper endoscopy is done to evaluate symptoms of persistent upper abdominal pain, nausea, vomiting or difficulty swallowing.

Your gastroenterologist will use a thin, flexible tube called an endoscope. This instrument is similar to a telescope, which lets the doctor clearly see the inside of your esophagus and stomach. If necessary, the doctor can take a tissue sample (biopsy), but you will not feel this. You will be in our office for one to three hours, from the time you arrive in our office until the time you are ready to leave.
