Colonoscopy
A colonoscopy is a procedure that allows a colon and rectal surgeon to view the inner lining of a patient’s colon and rectum. The procedure is performed using a thin, flexible tube (a colonoscope) that is slowly guided through the colon. The end of the colonoscope is lighted and includes a camera that transmits images onto a screen in the procedure room. These images can reveal inflammation, ulcers and even cancerous or pre-cancerous growths within the intestines.
