Video-assisted thoracoscopic surgery versus posterolateral thoracotomy lobectomy: A more patient-friendly approach on postoperative pain, pulmonary function and shoulder function

摘要

We evaluated the physiological benefits following video-assisted thoracoscopic surgery (VATS) lobectomy or posterolateral thoracotomy (PLT) lobectomy for lung cancer patients. One hundred and three patients were included in this study, who underwent either a VATS approach (n= 51) or a PLT approach (n= 52) lobectomy for clinical stage I lung cancer. Pain scores were measured preoperatively and on postoperative day (POD) one, three, seven, 30, and 90, by using a visual analog scale. Pulmonary function and shoulder function were measured preoperatively and on POD seven, 30 and 90 by using a portable spirometer and by the American Shoulder and Elbow Surgeons (ASES) standardized shoulder assessment form, respectively. Postoperative pain was experienced less in the VATS group than in the PLT group on POD one, three, seven, 30, and 90 (P= 0.060, 0.055, 0.000, 0.000, 0.000, respectively). Analgesic requirements were significantly less in the VATS group than in the PLT group during hospital stay (90.2 +/- 60.8mg vs. 119.2 +/- 70.8mg, P= 0.028). The pain score returned to the preoperative reference level on POD seven in the VATS group, but not until POD 30 in the PLT group. The recovery of forced vital capacity (FVC) was statistically better in the VATS group on POD seven, postoperative month (POM) one, and POM three (P= 0.000, 0.000, 0.002, respectively). The recovery of forced expiratory volume in 1 second (FEV1) was better in the VATS group, but the differences were not significant. The shoulder function in the VATS group was significantly well preserved on POD seven, 30 and 90, compared with the PLT group. Lobectomy by the VATS approach generates less pain, and preserves better pulmonary function and shoulder function in the early postoperative phase.
