Background: Interstitial Lung Disease (ILD) is a heterogeneous group of diseases characterized by in-flammation and fibrosis of the lung. Diagnosis based exclusively on clinical or radiologic patterns may be inaccurate, and if a reliable diagnosis cannot be made, surgical lung biopsy can be strongly considered to increase the diagnostic yield after multidisciplinary committee. Objective: To review the diagnostic results, morbidity, and mortality of surgical biopsies in a chilean public health institution. Patients and Method: Retrospective cohort of patients operated for diagnostic purposes for ILD between 2010-2020. Surgical biopsies done for other diagnoses were excluded. Results: 38 patients were included, with a median age of 63 years, 47% were female. Only 1 patient (2.6%) underwent emergency surgery and 89.5% underwent minimally invasive surgery techniques. 5 patients had some morbidity (13.1%), 4 of them being air leak. All complications were successfully managed conservatively. We had no readmission, reopera-tions, or 90-day mortality in this cohort. In 95% of the cases an accurate diagnosis of ILD was reached after multidisciplinary discussion. Discussion: In our experience surgical lung biopsy has a high diagnostic yield and a low morbidity and mortality. A low number of emergency procedures and accurate surgical indication by an expert committee could explain the low morbidity. Conclusion: Surgical lung biopsy in a general hospital reach a high diagnostic performance when discussed in a multidisciplinary committee to specify the diagnosis in ILD, with low morbidity and mortality if patients are properly selected.
