This study aimed to establish a predictive model for prolonged air leak (PAL) after video-assisted thoracic surgery (VATS) lung resection; and additionally, to present a meta-analysis of the relevant literature to estimate the association between various clinical factors and PAL. ⋯ 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.
