OBJECTIVE: The effects of lung metastasectomy on respiration were evaluated. SUBJECTS: From 1961 to 1999, 203 patients underwent lung metastasectomy. Of these, 102 patients who had undergone only partial lung resection, had undergone sufficient respiratory function testing, and had not suffered from other lung disease were included. RESULTS: Unilateral thoracoscopic surgery caused less decrease in percent vital capacity than surgery through a posterolateral thoracotomy, in both the early (rate of decrease: 16.2 +/- 9.1 vs. 33.0 +/- 12.0%, p < 0.01), and the late postoperative period (2.0 +/- 4.5 vs. 17.8 +/- 6.0%, p < 0.0001). Two thoracoscopic operations caused less decrease in percent vital capacity than 2 operations through a posterolateral thoracotomy (21.3 +/- 13.8 vs. 61.1 +/- 8.1%, p = 0.02). Bilateral metastasectomy through a median sternotomy caused less decrease in percent vital capacity than that through posterolateral thoracotomies (45.5 +/- 13.7 vs. 60.8 +/- 8.8%, p < 0.05). Four (36%) of 11 patients who had undergone 3 or more metastasectomies exhibited dyspnea of degree 3 or higher on the Hugh-Jones classification. CONCLUSIONS: Thoracoscopic metastasectomy and metastasectomy through a median sternotomy caused less restrictive respiratory dysfunction than metastasectomy through a posterolateral thoracotomy. Since metastatic lung disease often necessitates repeated metastasectomy, and repeated metastasectomy often causes severe restrictive respiratory dysfunction, metastasectomy should be performed with a less invasive procedure.
