Risk factors associated with prolonged air leak after video-assisted thoracic surgery pulmonary resection: a predictive model and meta-analysis

Lung stapling length and early postoperative drainage are important indicators for the evaluation of PAL occurrence. Upper pulmonary resection is a factor with particular regional differences as its association with PAL is not significant within Asian populations. Our nomogram, incorporating multiple factors, provided a simple and practical predictive model with value for clinical application.
