Thoracoscopy

Thoracoscopy is used to view the lung and the space surrounding the lungs (pleural space). Doctors may use it to view the lungs and pleura when less invasive tests do not give conclusive results.

Thoracoscopy can also be used for certain surgical procedures. When it is used for surgery, the procedure is often referred to as video-assisted thoracoscopic surgery (VATS).

The most common means for obtaining a sample of lung tissue for a biopsy is with a thoracoscope. Besides being able to view the lung surface and pleura, a doctor may take samples of tissue for microscopic examination and culture. A thoracoscope also may be used to drain accumulations of fluid in the pleural space (pleural effusions). In certain cases, the doctor gives drugs through the thoracoscope to prevent a reaccumulation of fluid in the pleural space.
