[The role of video-thoracoscopy in thoracic surgery]

The widespread acceptance of minimal invasive techniques has revolutionized the practice of surgery including, thoracic surgery. Within a short period of time, video-assisted thoracic surgery (VATS) has become an acceptable approach to a wide range of thoracic procedures. The use of VATS as a diagnostic modality is now well established. For therapeutic procedures, VATS has also been generally accepted as the treatment for spontaneous pneumothorax, thoracic sympathectomy, treatment of loculated effusions and resection of simple mediastinal cysts and benign tumors. Its role in major procedures, e.g. anatomic lung resections and thymectomy, however, remain poorly defined at present although some of the existing intermediate results are encouraging. The technique continues to evolve, with further miniaturization to reduce access-induced trauma. No matter how attractive the new techniques may appear, carefully conducted clinical trials should precede the general acceptance and widespread use.
