Abstract

Background: Uniport video-assisted thoracoscopic surgery (VATS) has emerged as a less invasive approach for the treatment of non-small cell lung cancer (NSCLC). However, whether uniport VATS has more potential advantages over multiport VATS remains controversial. This meta-analysis aimed to compare the perioperative efficacy of uniport and multiport VATS for T1–3N0M0 NSCLC.
Methods: An electronic and manual search of literature published before 1st October 2017 was conducted using PubMed, Embase, Web of Science, and the Wiley Online library. The effective values of dichotomous variables or continuous variables were estimated by odds ratios (OR) or by standardized mean differences (SMD) with 95% confidence intervals (CIs) respectively.
Results: Eleven relevant observational studies were included for meta-analysis. Results demonstrated that patients in the uniport group had a significant reduction in the duration of postoperative drainage (uniport: 4.39±2.48 vs. multiport: 4.99±3.24 days; P=0.003), bleeding volume (97.7±60.0 vs. 116.7±99.7 mL; P=0.006), length of hospital stay (6.3±2.4 vs. 7.0±3.6 days; P<0.001), VAS of postoperative pain (2.53±0.73 vs. 4.22±0.71, P=0.004) and in the overall rate of complications (14.5% vs. 17.5%; P=0.008). There were no significant differences between the two treatment groups with regards to mortality, operative time, the number of dissected lymph nodes or the conversion rate.
Conclusions: Uniport VATS might have represent a preferable option for the treatment of T1–3N0M0 NSCLC, due to its superior perioperative efficacy.
