Background and Objectives: Metastasectomy proved to be the choice treatment in the case of pulmonary metastasis. In this study we assessed the impact on survival of three types of resection: minimal by laser or conventional device and lobectomy. Methods: We considered 85 patients who underwent lung metastasectomy for tumors that originated from various sites. Fifty-two minimal resections were accomplished in 34 patients by conventional (diathermy dissection or stapler suture line) device, 59 resections in 29 by Nd:YAG laser. Lobectomies were 22, Minimum follow up required was 2 years. Results: The 3-year Kaplan-Meier survival rate was 63%, 44%, 53% for laser, conventional resections and lobectomy. The 5-year survival was 40%, 28%, 26% respectively. Among the groups there was no significant difference (P = 0.15). Laser patients showed shorter periods of air leakage and hospital stay. Conclusions: The type of resection did not disclose statistically significant differences on survival. Minimal surgery, especially by laser device, is recommended for less morbidity. J. Surg.

Fifty-two minimal resections were accomplished in 34 patients by conventional (diathermy dissection or stapler suture line) device, 59 resections in 29 by Nd:YAG laser.
