ABSTRACT
Lung cancer remains a leading cause of cancer-related mortality, with surgical resection as a primary treatment modality. However, postoperative wound infections (PWIs) pose significant risks following thoracoscopic radical resection. This study aims to identify the risk factors and pathogenetic characteristics associated with PWIs in lung cancer surgery. A comprehensive retrospective study was conducted from August 2021 to June 2023 at our institution. The study included 30 patients who developed PWIs and 60 controls who did not, following thoracoscopic radical resection for lung cancer. We evaluated various factors including age, hospital stay, intraoperative blood loss, body mass index (BMI), operation time, prophylactic antibiotic use, diabetes mellitus and tumour staging. Diagnostic criteria for PWIs were based on clinical signs and microbiological confirmation. Statistical analysis was performed using SPSS software, utilizing chi-square tests, and univariate and multivariate logistic regression analyses. The predominant pathogens identified in PWIs were Escherichia coli, Klebsiella pneumoniae and Pseudomonas aeruginosa. Univariate analysis revealed operation time (≥4 h) and diabetes mellitus as significant risk factors for PWIs, while prophylactic antibiotic use was associated with a lower incidence of PWIs. Multivariate analysis further confirmed these findings, highlighting prolonged operation time and diabetes as significant predictors of PWIs, and antibiotic use as a protective factor. Prolonged operation time and diabetes mellitus significantly increase the risk of PWIs following thoracoscopic radical resection for lung cancer, whereas prophylactic antibiotics play a protective role. These findings underscore the importance of tailored preventive strategies in clinical practice to minimize the occurrence of postoperative infections and improve surgical outcomes in lung cancer patients.
