CT-based emphysema score is associated with prolonged air leak after lung resection: a retrospective cohort study.

ABSTRACT:

Background

Prolonged air leak (PAL) is a common complication after lung resection for non-small cell lung cancer (NSCLC). This retrospective cohort study investigates the association between computed tomography (CT)-based emphysema score and PAL in patients undergoing lung resection for NSCLC.

Methods

Patients who underwent lung resection for pathological stage I-IIIA NSCLC at a single institution [2010-2021] were identified. Exclusion criteria included neoadjuvant therapy, missing preoperative chest CT, pneumonectomy, or bilobectomy. Chest CT-based emphysema score was defined as the percentage of emphysematous lung [density <-950 Hounsfield units (HU)] in the ipsilateral lung. PALs were defined as those lasting more than 5 days. Univariable and multivariable logistic regres
