Objective: To explore the influencing factors of rapid postoperative recovery in young(≤40 years old) lung cancer patients. Methods: Retrospective analysis was performed on 82 young patients with lung cancer diagnosed by postoperative pathology admitted to the department of thoracic surgery of the first affiliated hospital of Zhengzhou University from March 2013 to March 2019, the patients were divided into two groups according to their postoperative hospitalization time(hospitalization time≤7d, hospitalization time >7d). The preoperative medical history and examination data, intraoperative(operative method, embedding materials), postoperative complications and postoperative treatment and other data of the enrolled patients were collected to analyze the relationship between various factors and postoperative hospitalization time.Univariate analysis used t test or Fisher exact probability method, multivariate analysis used logistic regression model to analyze the data . Results: All 82 patients successfully completed the operation, and no death occurred during the perioperative period. There were no significant differences(P>0.05)according to the two groups of patients in the preoperative pulmonary function(FEV1) operation history, history of hypertension, diabetes, history of preoperative chemotherapy and surgery in the patients' position, blood transfusion, pleural adhesion, Czech, nai d, the use of xanthan gum, operation time, the maximum diameter and postoperative tumor thermal perfusion, fever, vomiting, choking cough, abdominal distension, etc.And it has significant differences(P<0.05). In the preoperative antibiotic use(P=0.002), the improvement of lung function(P=0.018), smoking history(P=0.024), medical reasons(P=0.011) and the operation(P<0.001), the lymph node excision scope(P<0.001), the lymph node dissection(P=0.017), hemostatic material use(P=0.023), blood loss(P=0.001) and postoperative average white blood cell count(P=0.033). Conclusion Preoperative and postoperative prophylactic use of antibiotics and drugs to improve pulmonary function were beneficial to postoperative recovery.Smoking was an independent risk factor for prolonged postoperative hospital stay.Minimally invasive operation and application of hemostatic materials can effectively shorten the postoperative hospitalization time of patients.
