AIMS: The aim of this study was to compare long term survival after resection of solitary pulmonary metastasis on CT scan performed by either thoracoscopy or through a standard thoracotomy. METHODS: Patients with a solitary, CT scan confirmed, peripherally located lesion suspected for metastasis, less than 3cm in diameter were included. End points were: postoperative complication rate, disease free and overall survival and location of recurrence in the lung. RESULTS: Thirty-five patients who underwent a thoracoscopic metastasectomy with (n=19) or without (n=16) confirmatory thoracotomy were included in this study. Patients experienced more complications following a thoracotomy (n=5) compared to those who had a thoracoscopy (n=0) (P=0.049). Two patients appeared to have further disease at thoracotomy besides the CT scan identified lesion, and some at thoracoscopy. At definitive histology, seven lesions were benign and eight appeared to be a second primary. Analysis of 20 patients with histological confirmed metastasis demonstrated a 2-year disease free and overall survival rate of 50% and 67% respectively following thoracoscopic metastasectomy (n=8) compared to 42% and 70% respectively following confirmatory thoracotomy (n=12). Recurrence occurred in three of the patients after thoracoscopic metastasectomy and in five patients after thoracotomy. CONCLUSION: Our results suggest that thoracoscopic resection of solitary peripherally located metastasis is a safe and potentially curative procedure with a long term outcome that is comparable with that after resection by thoracotom
