All procedures were performed under moderate sedation using intravenous midazolam and fentanyl.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 100 pulmonary nodules in 90 patients were subjected to ENB between October 2018 and May 2020. The median age of the study population was 66 (59\u201373). The mean diameter of the lung nodules was 27.9\u2009mm. The diagnostic yield of ENB\u2010guided biopsy was 53.0%. Although the nodule size (odds ratio: 1.055, <jats:italic>p<\/jats:italic> = 0.007) and positive bronchus sign (odds ratio: 2.918, <jats:italic>p<\/jats:italic> = 0.020) were associated with the diagnostic yield during univariate analysis, nodule size was the only independent variable on the multivariable analysis. Interestingly, the diagnostic yield showed an upward trend after 60 cases, from 45%\u201365%. Procedure\u2010related complications were reported in 16 cases; among these, pneumothorax occurred in three cases, and four cases experienced moderate bleeding. No instance of major bleeding or death was linked to ENB\u2010guided biopsy.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>ENB\u2010guided biopsy for high\u2010risk pulmonary nodules demonstrated an acceptable diagnostic yield and good safety profile.
