Thoracoscopic procedures for intrathoracic diseases: The present status

Thoracoscopic operations, alternatively termed as video-assisted thoracic surgery (VATS), are replacing the variety of surgical procedures which have been otherwise performed by open thoracotomy. The minimally invasive nature of the procedure, reduced postoperative pain, shortened hospital stay, and reduced cost, are the potential advantages of VATS. While these merits are being proven, the limits to this technique are also getting clearer. In fact, VATS has already become a standard treatment of choice in several diseases, such as bullectomy for spontaneous pneumothorax and biopsy for indeterminate nodule and diffuse interstitial lung disease, while others, such as major video-assisted lung resection for lung carcinoma and resection of metastatic lung tumour, await further evaluation of their roles in terms of oncological and technical aspects. Three issues that currently need to be addressed as the present role of thoracoscopy evolves are instrumentation, economics, indication, and end results in certain procedures.
