title: [Diagnostic bronchoscopy].
abstract: Endoscopic technology has developed markedly with endobronchial ultrasonography (EBUS) having become dramatically widespread over the past 10 years. EBUS-guided transbronchial needle aspiration (EBUS-TBNA) has become an important modality for the mediastinal staging of lung cancer as well as mediastinoscopy. The combination of EBUS with a guide sheath( EBUS-GS) and virtual navigation systems, such as Bf-NAVI, LungPoint, superDimension/Bronchus system, is useful for diagnosis of small peripheral pulmonary lesions. Moreover, the ability to observe lesions has increased using picture enhancement developed by new methods such as autofluorescence imaging( AFI), narrow band imaging (NBI), and FUJI intelligent color enhancement( FICE). However, these modalities have limited value in detection of lung cancer and preneoplastic lesions. In recent years, the indications for AFI have widened and it can be now used for evaluation of tumor extension. Knowledge of these new technologies is certainly useful to allow their routine clinical use by respiratory surgeons. We will review these new technologies in this paper.
