Mediastinoscopy is a surgical procedure to look at the inside of the upper chest between and in front of the lungs (mediastinum). During a mediastinoscopy, a small cut (incision) is made in the neck just above the breastbone or on the left side of the chest next to the breastbone. Then a thin scope (mediastinoscope) is inserted through the opening.
A colonoscopy is a procedure that allows the doctor to visually examine the entire lining of the colon and rectum using a colonoscope (a long flexible tube about the thickness of a finger). The colonoscope is inserted into the rectum and gradually advanced through the colon.
