Comparison of single utility port video-assisted thoracoscopic surgery (VATS) and three-port VATS for non-small cell lung cancer

Clinical efficacy of single utility port video-assisted thoracoscopic surgery (VATS) and three-port VATS for patients with non-small cell lung cancer (NSCLC) was compared. A total of 156 patients with NSCLC who underwent VATS in Taizhou Hospital of Zhejiang Province from July 2015 to January 2017 were selected as subjects. They were randomly divided into group A (n=74) and group B (n=82), in which group A was treated with single utility port VATS and group B was treated with three-port VATS. Perioperative indicators such as operation time, intraoperative blood loss, postoperative drainage, removal of drainage tube, lymph node dissection, hospitalization time, postoperative complications, postoperative pain and postoperative quality of life were observed. Expression levels of CRP and IL-6 in serum were detected by enzyme-linked immunosorbent assay (ELISA). There was no significant difference in the operation time, postoperative drainage volume, drainage tube removal time and lymph node dissection between groups A and B (P>0.05). Blood loss and hospitalization time in group A were significantly lower than those in group B (P<0.001). VAS scores at 1–3 days after operation in group A were significantly lower than those in group B (P<0.001). Levels of serum CRP and IL-6 at 1–7 days after operation in group A were significantly lower than those in group B (P<0.001). Incidence of complication in group A was not significantly different from that in group B (P>0.05). Overall quality of life scores of group A and B were significantly lower than the preoperative scores (P<0.001). Overall status score of group A was significantly higher than that of group B (P<0.001). Clinical efficacies of single utility port VATS and three-port VATS were similar. Single utility port VATS can reduce trauma during surgery, reduce stress response, relieve postoperative pain, and facilitate the recovery of postoperative quality of life.
