Effects of da Vinci robot versus thoracoscopic surgery on body trauma and lymphocyte subsets in lung cancer patients: A propensity score matching study

Background To assess the impact of da Vinci robot versus thoracoscopic surgery on body trauma and lymphocyte subsets in lung cancer patients. Methods Retrospective analysis of 352 patients with lung cancer treated by minimally invasive surgery completed by the same operator in the Department of Thoracic Surgery, Gansu Provincial People's Hospital from October 2019 to October 2022. According to the surgical procedure, the patients were divided into a robotic‐assisted thoracic surgery (RATS) group (n = 159) and a video‐assisted thoracoscopic surgery group (VATS) (n = 193), respectively. Propensity score matching (PSM) analysis was performed in both groups, and perioperative indicators were recorded. Levels of inflammatory markers (C‐reactive protein, CRP; interleukin‐6, IL‐6) and lymphocyte subsets (CD3+, CD4+, CD8+, and CD4+/CD8+) were measured 1 day before surgery and 1, 3, and 5 days after surgery, respectively. To compare the effects of the two surgical procedures on the trauma and lymphocyte subsets of the patient's organism. Results One hundred and thirty‐eight patients in each group after PSM. Compared with the VATS group, the RATS group had shorter operative time (p
