Survival After Thoracoscopic Surgery or Open Lobectomy: Systematic Review and Meta-Analysis.

Background: Video-assisted thoracoscopic surgery (VATS) has been shown to reduce hospital stays and pain compared with open lobectomy to treat non-small cell lung cancer. Because of the low rate of deaths, it is difficult to show differences in survival in individual studies. The objective of this study was to compare short- and long-term mortality by means of a systematic review and meta-analysis.
