title: Non-intubated video-assisted thoracic surgery: where does evidence stand?
abstract: In recent years, non-intubated video-assisted thoracic surgery (NIVATS) strategies are gaining popularity worldwide. The main goal of this surgical practice is to achieve an overall improvement of patients' management and outcome thanks to the avoidance of side-effects related to general anesthesia (GA) and one-lung ventilation. The spectrum of expected benefits is multifaceted and includes reduced postoperative morbidity, faster discharge, decreased hospital costs and a globally reduced perturbation of patients' well-being status. We have conducted a literature search to evaluate the available evidence on this topic. Meta-analysis of collected results was also done where appropriate. Despite some fragmentation of data and potential biases, the available data suggest that NIVATS operations can reduce operative morbidity and hospital stay when compared to equipollent procedures performed under GA. Larger, well designed prospective studies are thus warranted to assess the effectiveness of NIVATS as far as to investigate comprehensively the various outcomes. Multi-institutional and multidisciplinary cooperation will be welcome to establish uniform study protocols and to help address the questions that are to be answered yet.
