An endoscopy is performed to diagnose ulcers, acid reflux, celiac disease. They are also used to help doctors determine the cause of upper abdominal pain, difficulty swallowing, vomiting or gastrointestinal bleeding.
During an endoscopic procedure, patients lie on their back or side on an examination table. An endoscope is carefully fed down the esophagus and into the stomach and duodenum.
A small camera mounted on the endoscope transmits a video image to a video monitor, allowing close examination of the intestinal lining. Air is pumped through the endoscope to inflate the stomach and duodenum, making them easier to see. Special tools that slide through the endoscope allow the doctor to perform biopsies, stop bleeding, and remove abnormal growths.
Before an upper endoscopy, you may receive a local, liquid anesthetic that is gargled or sprayed on the back of the throat. The anesthetic numbs the throat and calms the gag reflex. An intravenous (IV) needle is placed in a vein in the arm if a sedative will be given. Sedatives help patients stay relaxed and comfortable.
