Rationale: Video-assisted thoracoscopic surgery (VATS) remains the gold standard for interstitial lung disease (ILD) characterization when histology is deemed necessary. There is diminishing use of VATS owing to increased reliance on high-resolution computed tomographic patterns, as well as concerns regarding the potential morbidity and mortality of the procedure.Objectives: The goal of this study was to evaluate the safety and tolerability of VATS among a broad group of patients with ILD referred to a tertiary care center.Methods: Data for all patients with ILD who underwent VATS lung biopsies at Inova Fairfax hospital for the period from December 2012 to September 2019 were collected. Clinical, physiologic, and functional parameters as well as postoperative outcomes including any complications, hospital length of stay, and mortality were collated.Results: There were 268 diagnostic VATS biopsies performed during the period. The mean age of the cohort was 63 ± 13 years, 54% were male, and 25% were ultimately diagnosed with idiopathic pulmonary fibrosis. Two hundred twenty-nine patients were scheduled (85%, Elective VATS group) whereas 39 were inpatients (15%). In the elective group, the 1-month complication rate was 8%, whereas 4% had a severe complication, and there were no deaths. The only mortalities were in the group who were hospitalized before the VATS (4/39 = 10%). Complications were less frequent when VATS was requested by the tertiary referral ILD team. Of the elective group, 87% patients were discharged the same day.Conclusions: This report demonstrates the safety, tolerability, and feasibility of VATS lung biopsy as a same-day procedure in the modern era, especially if patients are first vetted by a team with expertise in the field of ILD. These results support a lower threshold to pursue a VATS biopsy when histology is required for an ILD diagnosis.
