A retrospective study of diaphragmatic motion, pulmonary function, and quality-of-life following video-assisted thoracoscopic lobectomy in patients with nonsmall cell lung cancer.

Abstract

Diaphragmatic dysfunction and its negative physiologic disadvantages are less commonly reported in patients with lung cancer video-assisted thoracoscopic lobectomy. The aim of this study was to investigate the outcomes of this complication on pulmonary function and quality-of-life in patients following video-assisted thoracoscopic lobectomy. The aim of this study was to investigate potential benefits on pulmonary function and quality-of-life with normal diaphragmatic motion. A retrospective study was conducted in 64 patients with nonsmall cell lung cancer after video-assisted thoracoscopic lobectomy. The population were divided into groups 1 (with diaphragmatic paralysis, n = 32) and group 2 (without diaphragmatic paralysis, n = 32) according diaphragmatic motion after postoperatively 6 months. And then, we investigated the difference between the two groups on pulmonary function and quality-of-life. (1) At 6 months after resection, the patients in group 1 had lost 25% of their preoperative forced expiratory volume in the 1 s (FEV 1 ) (P < 0.001), and the patients in group 2 had lost 15% of their preoperative FEV 1 (P < 0.001). And the other spirometric variables in group 1 were significantly worse than that of group 2 (P < 0.001). (2) The most frequently reported postoperative symptoms were fatigue, coughing, dyspnea, and thoracotomy pain in two groups. Of all the symptom scales, only the dyspnea scale showed a significant difference which subject has a higher proportion and scale compared to control. The present study indicates that unilateral diaphragmatic paralysis following video-assisted thoracoscopic lobectomy caused adverse effects on postoperative pulmonary function and quality-of-life.
