Development and validation of a predictive model for chronic pain after thoracoscopic pulmonary resection

Background Chronic postsurgical pain (CPSP) is a major complication following video-assisted thoracoscopic surgery (VATS) for lung resection. Despite its clinical importance, the reported incidence of CPSP varies considerably across studies, and a standardized tool for risk prediction remains lacking. This study aimed to identify predictors associated with CPSP after VATS lung resection within a single-center prospective observational cohort and to develop predictive models to guide personalized
