Upper Endoscopy also known as Esophagogastroduodenoscopy (EGD) with biopsy is a procedure usually performed by a gastroenterologist (GI or intestinal doctor). This test involves passing an endoscope, a long, flexible black tube with a light and video camera on one end, through the mouth to examine the esophagus, stomach and the first part of the small intestine called the duodenum. The advantages of this test over the barium esophagram (X-ray test) are that the lining of the upper digestive tract can be directly viewed by the doctor and also very small abnormalities are seen.
Endoscopic therapies can be performed at the time of the procedure.
Your doctor might start the treatment by spraying your throat with a local anesthetic or by giving you a sedative to help you relax. You'll then lie on your side, and your doctor will pass the endoscope through your mouth and into the esophagus, stomach and duodenum. The endoscope doesn't interfere with your breathing, most patients consider the test only slightly uncomfortable, and many patients fall asleep during the procedure.
After the surgery, your throat might be a little sore, and you might feel bloated because of the air introduced into your stomach during the test. You will be able to eat after you leave unless your doctor instructs you otherwise.
