Thoracoscopy
In thoracoscopy, a thin, flexible viewing tube (called a thoracoscope) is inserted through a small incision in the chest. Fiberoptic cables permit the surgeon to visually inspect the lungs, mediastinum (the area between the lungs), and pleura (the membrane covering the lungs and lining the chest cavity). In addition, surgical instruments may be inserted through other small incisions in the chest, to perform both diagnostic and therapeutic procedures.
