An upper gastrointestinal (UGI) endoscopy is a procedure that allows a doctor to look at
the interior lining of the esophagus, stomach, and the first part of the small intestine
(duodenum) through a thin, flexible viewing instrument called an endoscope. The tip of
the endoscope is inserted through the mouth and then gently moved down the throat into
the esophagus, stomach, and duodenum (upper gastrointestinal tract).
Since the entire upper gastrointestinal (GI) tract can be examined during this test, the
procedure is sometimes called esophagogastroduodenoscopy (EGD).
Using the endoscope, the 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.
In medicine (gastroenterology), Esophagogastroduodenoscopy is a diagnostic
endoscopic procedure that visualizes the upper part of the gastrointestinal tract up to the
duodenum. It is considered a minimally invasive procedure since it does not require an
incision into one of the major body cavities and does not require any significant recovery
after the procedure (unless sedation or anesthesia has been used). A sore throat is also
