Abstract

To understand the effects of thoracoscopic approach to thoracotomy on lung function, we investigated the changes in lung function after thoracoscopic operation (n = 7) and compared them to those after standard posterolateral (n = 5) or muscle-sparing thoracotomy (n = 6). In 18 patients with benign lung tumor in which surgical treatment resected in partial resection of the lung tissue, we measured TLC, VC, RV, FEV1.0, FEV1.0%, Peak Flow and DLco preoperatively and at 2, 4 weeks postoperatively. In the standard posterolateral or muscle-sparing thoracotomy groups, FVC, TLC, FEV1.0 and Peak Flow decreased to about 80% of preoperative value at 2 weeks. At 4 weeks after operation, these values showed to increase some what, but did not reach to the preoperative value. Whereas, the thoracoscopic procedure group, did not show the decrease in lung function through the time course. There was not significant different between standard posterolateral and muscle-sparing thoracotomy. We conclude that thoracoscopic approach is an useful technique to thoracotomy because of its minimizing after thoracotomy effect of lung function loss.
