Bronchoscopes of the Twenty-First Century

Over the past century, bronchoscopy has become an essential tool for pulmonologists and thoracic surgeons, who for many years have employed bronchoscopy with such therapeutic modalities as laser therapy, electrocautery, cryotherapy, and stent placement. Over the past decade, advanced imaging techniques, such as autofluoresence bronchoscopy, electromagnetic navigation, narrow-band imaging, confocal fluorescence microendoscopy, and endobronchial ultrasound, have greatly expanded the diagnostic utility of bronchoscopy. This article reviews the technological advances in the field of diagnostic bronchoscopy.
