Thoracoscopic approach to lung metastases.

Surgical resection of lung metastases has become routine and the introduction of video assisted thoracic surgery (VATS) has provided a mini-invasive option to this treatment. However, oncological radicality of VATS is criticized especially in the event of deeply located lesions requiring manual palpation and lymph node dissection. At today, VATS lung metastasectomy is performed with diagnostic purposes or with curative intent as initial resection in patients with one to a few, peripherally located lesions. New perspectives are represented by the transxiphoid port, which may allow hand palpation during VATS, and awake lung metastasectomy in epidural anesthesia, which can permit a reduction of global operating room time. In conclusion, VATS metastasectomy is valid in selected but increasing number of patients, without compromising oncologic radicality.
