RESUMO
Flexible bronchoscopy is a brief procedure routinely performed under local anaesthesia or under sedation by pulmonologist. These days flexible bronchoscopy is more widely used for diagnostic as well as therapeutic purposes without much morbidity or complications. Flexible bronchoscopy gives better access to the tracheo-bronchial tree with its more flexible tip to reach upper lobe areas and greater patient comfort as compared to rigid bronchoscopy. Here, we present few cases of infectious as well as non-infectious diseases who were diagnosed only after diagnostic bronchoscopy was done. All patients have typical presentation on bronchoscopy. Diagnostic bronchoscopy should be done at the earliest for early diagnosis and better disease outcome.
