Comparison of single-stage and two-stage bilateral video-assisted thoracic surgery

Abstract

Objective Single-stage sequential bilateral video-assisted thoracoscopic surgery (VATS) is a controversial procedure. In the present study, we retrospectively compared the outcomes of single-stage and two-stage VATS. Methods This study involved patients who underwent single-stage sequential bilateral VATS (SS-VATS group) or two-stage VATS at a 3-month interval (TS-VATS group) for treatment of non-small cell lung cancer from 2010 to 2018. The major outcome was the comparison of intraoperative changes. Results The inspiratory peak pressure was higher, the incidences of intraoperative hypoxia and unstable hemodynamics were higher, the surgical time was longer, and the durations of the intensive care unit stay and postoperative hospitalization were longer in the SS-VATS group than in the TS-VATS group. However, the chest tube duration, incidence of postoperative mechanical ventilation, and clinical complications were not different between the two groups. Conclusions Compared with two-stage VATS, single-stage sequential bilateral VATS can be performed for successful treatment of bilateral pulmonary lesions with a shorter total time and higher cost-effectiveness in terms of anesthesia and hospitalization but with a higher incidence of intraoperative adverse effects and a longer hospital stay.
