Endoscopy
About Endoscopy
An upper endoscopy (EGD) allows the doctor to see the upper GI tract including the esophagus, stomach and the duodenum. This procedure is used to evaluate symptoms such as difficulty swallowing, reflux, vomiting, upper abdominal pain, and others.
Patients are completely sedated during the procedure while their doctor examines the esophagus, stomach and duodenum using a thin, lighted, flexible tube (called an endoscope).
During the procedure, the doctor will be looking for signs of abnormal tissue. If they see an area that needs further evaluation, they might take a small sample of the tissue lining to be analyzed. This testing can help test for several different conditions that may explain a patient’s symptoms.
For patients experiencing chronic difficulty swallowing, the doctor can pass instruments through the endoscope to stretch a narrowed area of the esophagus.
