Pulmonary function changes after different extent of pulmonary resection under video-assisted thoracic surgery

Abstract

In minimal invasive surgery, wedge resection best preserves pulmonary function with similar spirometry change with VATS mediastinal procedures without lung resection. Compared with VATS lobectomy, VATS segmentectomy may help minimize loss of FVC but not FEV1 or DLCO. Pulmonary function loss per segment resected is doubled after VATS segmentectomy than after lobectomy. These results should be taken into account when deciding the extent of resection for patients with early stage lung cancer.
