Abstract
We designed this study to investigate the rate and risk factors of prolonged air leak (PAL) in patients undergoing pulmonary segmentectomy in our unit. We performed a retrospective cohort study on 191 patients undergoing pulmonary segmentectomy (January 2017-August 2021). A PAL was defined as an air leak >5 days. One hundred and sixty-eight segmentectomies were performed using video-assisted thoracoscopic surgery (VATS), 13 were open operations and 10 were robotic. PAL occurred in 36 patients (19%). Their average post-operative stay was 2.4 days longer than those without PAL. Logistic regression analysis showed that a low preoperative carbon monoxide lung diffusion capacity (DLCO) (OR 0.98, P<0.001), low body mass index (BMI) (OR 0.95, P=0.002) and the performance of complex segmentectomies (OR 2.2, P<0.001). were significantly associated with PAL. Pulmonary segmentectomies are associated with a not negligible risk of PAL when using real world data, especially in patients with compromised pulmonary function and after complex segmentectomies. This finding is useful to inform the decision-making process.
