Robotic Assisted Major Lung Resection in Elderly Patients

The investigators will recruit all patients who underwent major lung resection (segmentectomy, lobectomy, bilobectomy, or pneumonectomy using a robotic system) from May 2015 to December 2022. Patients are divided into two groups: older than 80 years (case- very elderly patients) and younger than 80 years (control- elderly). the aim: Minimally invasive techniques such as robot-assisted thoracoscopic surgery (RATS) can potentially reduce surgical trauma and therefore prove particularly beneficial for elderly patients.
