Upper endoscopy
Upper endoscopy test allows a physician to view the esophagus, stomach and deudenum. Upper endoscopy is also referred to as esophagogastroduodenoscopy (EGD) or panendoscopy. Patients suffering from persistent upper abdominal pain, vomiting, nausea or difficulty in swallowing may need to undergo upper endoscopy to identify the cause. Upper endoscopy can also be used for collecting biopsy sample. Polyps can be removed and possible causes for upper GI bleeding can be located.
Upper endoscopy aids in diagnosing peptic ulcer disease. Upper endoscopy is invaluable in detecting H. pylori infection. A patient scheduled for upper endoscopy must come on a empty stomach. The patient is asked to lie on his left side. A small bite block is inserted into the mouth. The endoscope is passed through the mouth into the esophagus, stomach and duodenum. A numbing solution is sprayed on the throat and sedative and pain alleviating medicine is also given to the patient. Images of the esophagus, stomach and duodenum can be seen by the physician on a monitor. Air is blown into the stomach to aid examnation. Patients on medications for hypertension, heart condition or thyroid problems must keep the physician informed.
