Abstract:
BACKGROUND: In the past decade, many researchers focused on Robotic- Assisted Thoracoscopic Surgery (RATS), which has been introduced as an alternative minimally invasive approach, versus Video- Assisted Thoracoscopic Surgery (VATS) for lung lobectomy in patients with non-small cell lung cancer. However, the advantage of RVATS compared to VATS is still under investigation. The results are unclear. AIM: The aim of this study is to compare the efficacy and safety of Robot-assisted Thoracic Surgery (RATS) lobectomy versus Video-assisted Thoracic Surgery (VATS) for lobectomy in patients with Non- Small Cell Lung Cancer (NSCLC). METHODS: A systematic electronic search of online electronic databases: Pubmed, Embase, Cochrane library updated in June 2017. The meta-analysis was performed including the studies are designed as randomized or non- randomized controlled. RESULTS: Twenty retrospective cohort studies met our inclusion criteria. The pooled analysis of mortality showed that RATS lobectomy significantly reduced the mortality rate when compared with VATS lobectomy (RR =0.53, 95% CI 0.37 - 0.76; P = 0.0005). With the pooled result of duration of surgery indicated that RATS has a tendency towards longer surgery time (SMD= 0.52, 95% CI 0.23- 0.81; P < 0.0004=). However, the meta-analysis on the median length of hospital stay (MD =0.00, 95% CI -0.03 - 0.03; P = 0.91), number of dissected lymph nodes station (SMD =0.39, 95% CI -0.60 - 1.38; P = 0.44), the number of removed lymph nodes (SMD =0.98, 95% CI -0.61 - 2.56; P = 0.23), mean duration of drainage (SMD =0.29, 95% CI -0.15 - 0.73; P = 0.20), prolonged air leak (RR =1.01, 95% CI 0.84 - 1.21; P = 0.93), arrhythmia (RR =1.06, 95% CI 0.88 - 1.26; P = 0.54) (P= 0.54), pneumonia (RR =0.89, 95% CI 0.69 - 1.13; P = 0.33), the incidence of conversion (RR =0.82, 95% CI 0.54 - 1.26; P = 0.37) and morbidity (RR =1.05, 95% CI 0.90 - 1.23; P = 0.055) all showed no significant differences between RATS and VATS lobectomy. CONCLUSIONS: RATS result in better mortality as compared with VATS. However, robotics seems to have longer operative time and higher hospital costs, without superior advantages in morbidity rates and oncologic efficiency. Since the advantages of RATS has been performed in some area, the continuation of a comparative investigation with VATS may be necessary. And some efforts need to be taken into consideration to reduce the operative time and cost.
