An Upper GI Endoscopy is a procedure that uses a long, thin, flexible tube called an endoscope, with a tiny video camera to look inside the esophagus and the beginning part of the small intestine. This procedure can be helpful in evaluating or diagnosing various problems such as difficulty in swallowing, stomach or abdomen pain, and ulcers.
Prior to the start of the procedure, you may be given a sedative or have your throat sprayed with a local anesthetic to help keep you comfortable. Once you are fully prepared, your doctor will gently maneuver the endoscope into position. During the procedure, you should feel no pain and it will not interfere with your breathing.
In some cases, it may be necessary to take a sample of tissue, called a biopsy, for later examination. This, too, is a painless procedure. In other cases, this endoscope can be used to treat a problem such as active bleeding from an ulcer.
