Outcomes were 3-year overall survival (OS), recurrence-free survival (RFS), and short-term outcomes (PAL \u22652 days; postoperative complications [Clavien-Dindo grade \u22653] and mortality). After 1:1 PSM, we compared ILD with COPD and explored group-specific risk factors.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The median postoperative air leak duration was 0 days (range: 0-13). Complications occurred in 3.6%, and mortality in 2.2% of cases. Three-year OS and RFS were 85.3% and 77.7%, respectively. ILD was a risk factor for recurrence (hazard ratio [HR] 6.29, 95% confidence interval [CI] 2.29-17.33; P\u2009&amp;lt;\u2009.001). After PSM (25 pairs), ILD showed worse RFS (P\u2009=\u2009.001) and OS (P\u2009=\u2009.010), while short-term outcomes were comparable. In ILD, interstitial abnormalities involving &amp;gt;1 lobe were a risk factor for recurrence (HR 13.74, 95% CI 2.78-67.95; P\u2009=\u2009.001), and combined pulmonary fibrosis and emphysema (CPFE) was a risk factor for PAL (odds ratio [OR] 7.94, 95% CI 1.32-47.62; P\u2009=\u2009.023). In COPD, ipsilateral pneumothorax history was a risk factor for recurrence (HR 15.50, 95% CI 1.81-133.20; P\u2009=\u2009.012).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>SSP appears safe for selected patients. Despite worse long-term outcomes in ILD, comparable short-term results support surgery when benefits are expected; caution is warranted in patients with interstitial abnormalities in &amp;gt;1 lobe,
