Medical Thoracoscopy is a procedure to examine the chest wall from the inside using an endoscope like device, called a thorascope, through a little hole (about 1-2 cm) in the chest. This also allows examiner to examine around the outside of the lungs apart from inside of the chest wall. During the procedure, samples are taken for establishing diagnosis of pleural disorders in the form of biopsies from the pleura (the covering of lungs and chest wall) and fluid. The procedure is done in our bronchoscopy suite under mild sedation (not general anaesthesia) and local anaesthesia. The total duration of the procedure is around 30-45min. The same sitting can also be used therapeutically for pleurodesis.
