The role of video-assisted thoracic surgery for pulmonary metastasectomy

Management of isolated metastatic deposits to the lungs and the role of surgical resection, specifically video-assisted thoracic surgery (VATS) techniques, have been controversial. The inability to perform a detailed bimanual palpation of the lung for occult lesions has been considered an inherent weakness in this approach. We have performed VATS resection for 205 patients with pulmonary metastatic disease and potentially curative VATS resec-tion for 119 patients. VATS resection was successfully performed for all VATS diagnostic and therapeutic patients, with no perioperative deaths. Longitudinal follow-up demonstrated a mean survival of 20 months in the diagnostic group and 32 months in the therapeutic group. In the VATS therapeutic group, 44 (37%) patients remain free of disease at a mean follow-up of 37 months. Of the 69 recurrences, 6% were local, 25% were regional, and 67% were distant. In this review, the present role of VATS pulmonary metastasectomy will be examined.
