An upper endoscopy allows your physician to examine the lining of your esophagus, stomach and duodenum (first part of the small bowel). This procedure is performed with an endoscope, which is a small flexible fiber-optic tube. The images are viewed on a video monitor. This is also called an EGD (esophagogastroduodenoscopy).
Why have an upper endoscopy?
Upper endoscopy is typically performed to help evaluate abdominal pain, nausea, vomiting or problems with swallowing. It is also used commonly for detecting bleeding in the upper GI tract, malabsorption or inflammatory.
