Background: The merits of spontaneous ventilation video-assisted thoracic surgery (SV-VATS) are still controversial. Our team retrospectively evaluated the intraoperative and postoperative advantages of this surgical approach, comparing with mechanical ventilation video-assisted thoracic surgery (MV-VATS).
Methods: We did a single center retrospective study at the First Affiliated Hospital of Yunnan Province. 244 patients were eventually assigned to the SV-group and MV-group, and their intraoperative indicators and thoracic surgery postoperative data were included in the comparison.
Results: The SV-group exhibited markedly less intraoperative bleeding and postoperative thoracic drainage, and the bleeding volume was correlated with the volume and duration of drainage. Further analysis showed that, patients undergoing SV-VATS had less activation of white blood cells and neutrophils after surgery, but they also had lower serum albumin concentrations. Risks of short-term postoperative complications, including inflammatory reactions, malignant arrhythmias, constipation, and moderate or more pleural effusions, were also significantly reduced in the SV-group. Additionally, hospitalization cost was lower in the SV-group than that in the MV-group.
Conclusions: SV-VATS is suitable for various types of thoracic surgery, and effectively reduce intraoperative bleeding and postoperative thoracic drainage. With less postoperative inflammatory response, it reduces the risk of short-term postoperative complications. It is also able to help to reduce the financial burden of patients.
