When you arrive at YRMC for your colonoscopy appointment, you receive a mild sedative to relax you and relieve potential discomfort. Your physician may order anesthesia for an even deeper level of sedation. During the exam, you lie on your left side. The doctor gently inserts the thin, flexible tube with a light and camera into the body and guides it to the colon.
Carbon dioxide gas—introduced through the scope—gives the physician a clear view of the large bowel and small intestine. Carbon dioxide gas is easily absorbed and provides for a comfortable recovery. The camera transmits a video image to a computer screen, allowing the physician to carefully examine the intestinal lining. The physician also removes any polyps and may take tissue samples for further testing during the colonoscopy.
