Short-term impact of video-assisted thoracoscopic surgery on lung function, physical function, and quality of life

Background: Video-assisted thoracoscopic surgery (VATS) has been increasingly used as an approach for lung lobectomy. However, the recovery of respiratory and physical function may be insufficient at discharge because the average length of hospital stay is decreasing after surgery. In this study, we investigated the changes in physical function, lung function, and quality of life (QOL) of lung cancer patients after VATS, and factors for QOL were also evaluated. Methods: The subjects of this study were 41 consecutive patients who underwent video-assisted lung lobectomy for lung cancer. Rehabilitation was performed both before and after surgery. Lung function testing, physical function testing (timed up and go test (TUG) and the 30-s chair-stand test (CS-30)), and QOL (EORTC QLQ-C30) were measured before and 1 week after surgery. Results: Postoperative VC recovered to 76.3% ± 15.6% 1 week after surgery. TUG, CS-30, and QOL were significantly worse after surgery (p < 0.05). Lung function and physical function were found to affect QOL. Postoperative complications included pneumonia in 1 patient. There were no patients who discontinued rehabilitation. Conclusion: Our rehabilitation program was safe and useful for patients after VATS.
