An endoscopy procedure will allow your physician to visually inspect your gastrointestinal tract. Upper endoscopy (also known as EGD) includes visualization of the esophagus (swallowing tube), stomach, and duodenum (first portion of the small intestine). Lower endoscopy is visualization of the colon (large bowel).

Your physician will give you medication through a vein to help you relax and better tolerate any discomfort during the procedure. A variety of instruments can be passed through the endoscope that allow the physician to stretch narrowed areas, take tissue biopsies and remove polyps.
