    Background: The aim of this study was to evaluate mortality and morbidity after surgical lung biopsy in patients with interstitial lung diseases and to investigate perioperative risk factors for complications. Methods: A total of 132 enrolled patients were divided into three groups: group 1 (70), patients with operation scheduled before admission; group 2 (48), patients with operation determined after medical therapy; and group 3 (14), patients with emergent operation followed by steroid therapy. Complications were classified according to the Clavien–Dindo system. The 30- and 90-day mortality and complication rates were evaluated, and perioperative risk factors were investigated. Results: Overall complication rate was 19.7%. The 30- and 90-day in-hospital mortality rates were 1.5% and 3.0%, respectively. Complication rates more than grade II were significantly different between the three groups (P = 0.045). Patients in group 1 revealed only class I or II complications and no mortalities. Elevated oxygen demand after operation was an independent risk factor for any complications, complications more than class II and any events (P < 0.001, P = 0.042 and P < 0.001, respectively). The New York Heart Association Functional Classification (NYHA) class IV was a statistically significant risk factor for any complications (P = 0.036, odds ratio 7.93). Higher NYHA class (III and IV) showed significantly higher risk in occurrence of any events after lung biopsy. Conclusion: Prepared surgical lung biopsy for interstitial lung disease is feasible with reasonable morbidity. Higher NYHA class and elevated oxygen demand after the surgery could imply post-operative outcomes. Alternative diagnostic methods such as transbronchial biopsy or bronchoalveolar lavage should be considered prior to surgical lung biopsy especially in high-risk patients.
