Post-operative volume changes in residual lung lobes after VATS pulmonary segmentectomy for early stage non-small cell lung cancer

Key Points

To investigate volume compensation mechanisms following VATS pulmonary segmentectomy in patients with early-stage non-small cell lung cancer (NSCLC).
Analyzed volume changes in residual lung lobes post-surgery
Compared upper-lobe and lower-lobe resection outcomes
Evaluated the absence of contralateral volumetric compensation
More significant volume reduction observed in upper-lobe resections compared to lower-lobe resections
Suggests potential for better lung function preservation after multiple resections
Identified specific volume compensation patterns important for surgical planning

Abstract

Volume compensation mechanisms occur after VATS segmentectomy, with more pronounced volume reduction following upper-lobe resections compared to lower-lobe resections. The absence of contralateral volumetric compensation may allow subsequent compensatory responses to occur and potentially contribute to a better preservation of lung function in patients undergoing additional pulmonary resections. Characterizing these patterns is important for surgical planning and optimizing postoperative management in patients undergoing segmentectomy for early-stage NSCLC.
