Editorial comment on: “Major morbidity after video-assisted thoracic surgery lung resections: a comparison between the European Society of Thoracic Surgeons definition and the Thoracic Morbidity and Mortality system” by Sandri A, et al.

The current issue of the Journal of Thoracic Disease publishes the remarkable work of Sandri and associates (1) which not only contributes to a deeper understanding of the distribution of postoperative complications, but also questions the traditional classification of major complications, in the framework of video-assisted thoracic surgery (VATS) lung resection.
