However, advancement of CT imaging offers multiplanar reconstruction facilitating enhanced preprocedure planning. This study aims to report efficacy and safety while considering the impact of patient selection and multiplanar CT planning.<jats:italic> Method.<\/jats:italic> Prospective case series of patients with peripheral lung lesions suspected of having lung cancer who underwent flexible bronchoscopy (forceps biopsy and lavage). Endobronchial lesions were excluded. Patients with negative results underwent CT-guided transthoracic needle aspiration, surgical biopsy, or clinical-radiological surveillance to establish the final diagnosis.<jats:italic> Results.<\/jats:italic> 226 patients were analysed. The diagnostic yield of bronchoscopy was 80.1% (181\/226) with a sensitivity of 84.2% and specificity of 100%. In patients with a positive CT-Bronchus sign, the diagnostic yield was 82.4% compared to 72.8% with negative CT-Bronchus sign (<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\"><mml:mi>p<\/mml:mi><mml:mo>=<\/mml:mo><mml:mn fontstyle=\"italic\">0.116<\/mml:mn><\/mml:math>). Diagnostic yield was 84.9% in lesions &gt; 20\u2009mm and 63.0% in lesions \u2264 20\u2009mm (<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M2\"><mml:mi>p<\/mml:mi><mml:mo>=<\/mml:mo><mml:mn fontstyle=\"italic\">0.001<\/mml:mn><\/mml:math>). Six (2.7%) patients had transient hypoxia and 2 (0.9%) had pneumothorax. There were no serious adverse events.<jats:italic> Conclusion.<\/jats:italic> Flexible bronchoscopy with appropriate patient selection and preprocedure planning is more efficacious in obtaining a diagnosis in peripheral lung lesions compared to historical data.
