Definition    Return to top

Mediastinoscopy with biopsy is a procedure in which a lighted instrument (mediastinoscope) is inserted through the neck to examine the structures in the top of the chest cavity, and a sample of tissue is taken.

How the Test is Performed    Return to top

This procedure is done in the hospital. You will be given general anesthesia so that you are asleep and do not feel any pain.

A tube (endotracheal tube) is placed in your nose or mouth to help you breathe. A surgical cut is made in the neck. A device called a mediastinoscope is inserted through this incision into the mid-part of the chest.

Tissue samples are taken, usually of the lymph nodes surrounding the airways. The scope is then taken out. The opening is closed with stitches.
