Q

A procedure where a rigid scope with a lens is passed through a trocar placed in the pleura via 1 or 2 small incisions in the intercostal muscles.
-The procedure of choice when appropriate as it is much less invasive than an open lung biopsy.
-A physician views the lesions on a monitor directly via the lens & biopsy specimens are taken.
-A chest tube is kept in place until the lungs expand.
-Lesions in the pleura or peripheral lung can be biopsied.
