Endoscopy is a nonsurgical procedure used to examine a person’s digestive tract. Using an endoscope, a flexible tube with a light and camera attached to it, your doctor can view pictures of your digestive tract on a color TV monitor.
During a minimally invasive procedure, surgeons make several small incisions in the skin — just a few millimeters, in some cases. A long, thin tube with a miniature camera attached at the end (called an endoscope) is passed through one of the incisions. Images from the endoscope are projected onto monitors in the operating room so surgeons can get a clear (and magnified) view of the surgical area. Special instruments are passed through the other openings. These instruments allow the surgeon to perform the surgery by exploring, removing, or repairing whatever’s wrong inside the body.
