Medical Thoracosopy is done to determine the presence or absence of lung and pleural diseases. The thorcoscopy is performed usually under local anaesthesia with conscious sedation, but rarely general anaesthesia may be required. The procedure involves introduction of the instrument in pleural space through a small hole in the chest wall. A chest tube is left in the pleural space after the procedure for the duration required. Every effort is made to conduct the procedure in such a way as to minimize discomfort and risks. However, just as with other types of prodedures, there are inherent potential risks of this procedure. The incidence of major and minor complications associated with thoracoscopy are 1.9% and 5.5%, respectively. The complications include prolonged air leak, hemorrhage, subcutaneous emphysema, postoperative fever, empyema, wound infection, cardiac arrhythmias, reexpansion pulmonary edema, hypotension and seeding of chest wall in patients with mesothelioma. The mortality rate associated with thoracoscopy performed is 0.09% or 1 death in 8000 procedures.
