RESUMO
Introduction@#The introduction of minimally invasive surgery has revolutionized multiple disciplines of surgical practice. @*Objectives@#This meta-analysis of matched case control studies aimed to compare the perioperative outcomes of video-assisted thoracic surgery (VATS) with open thoracotomy for patients with early-stage non-small cell lung cancer (NSCLC).@*Methods@#We searched from PubMed and Embase electronic database and revealed seven relevant studies. Endpoints included perioperative mortality and morbidity, postoperative complications and duration of hospitalization. Two investigators (L.S and D.N) independently reviewed each retrieved article. The values of RR and 95% CI were estimated. We used the fixed and random-effects models to estimate the size of the treatment benefit.@*Results@#Results indicate that perioperative mortality was similar between VATS and open thoracotomy (RR-0.62(95%CI 0.39-0.98). However, patients who underwent VATS were found to have fewer overall complications (RR-0.68(95%CI 0.59-0.78), and patients who underwent VATS had a significantly shorter length of hospitalization compared with those who underwent open thoracotomy (MD= -2.98(95%CI-4.09:-1.87)).@*Conclusions@#The present meta-analysis demonstrated superior perioperative outcomes for patients who underwent VATS, including overall complication rates and duration of hospitalization. Therefore, our study suggests that VATS should be performed widely to treat patients with lung cancer in the future.
