Thoracoscopy--state of the art.

"Medical" thoracoscopy as compared with "surgical" thoracoscopy (which is more precisely known as video-assisted thoracic surgery (VATS)) has the advantage that it can be performed under local anaesthesia or conscious sedation, in an endoscopy suite, using nondisposible rigid instruments. Thus, it is considerably less invasive and less expensive. The main diagnostic and therapeutic indications for medical thoracoscopy are pleural effusions and pneumothorax. Due to its high diagnostic accuracy, approaching almost 100% in malignant and tuberculous pleural effusions, it should be used when pleural fluid analysis and needle biopsy are nondiagnostic. In addition, medical thoracoscopy provides staging for lung cancer and diffuse malignant mesothelioma. Talc poudrage, as the best conservative method for pleurodesis in 1998, can also be performed with medical thoracoscopy. It can also be effectively used in the early management of empyema. In spontaneous pneumothorax it allows staging, thereby facilitating treatment decisions, and in addition coagulation of eventual blebs and talc poudrage for efficient pleurodesis. Medical thoracoscopy is a safe procedure which is even easier to learn than flexible bronchoscopy. Due to its high diagnostic and therapeutic efficiency, it should be applied increasingly in the management of the above-mentioned pleuropulmonary diseases.
