title: [Endobronchial ultrasound transbronchial needle aspiration initiation into the Lyon Sud hospital center: Experience of the first three years].
abstract: BACKGROUND
  Endobronchial ultrasound is a recent technique for the diagnosis and the lymph node staging in lung cancer. It also showed interest in non tumoral mediastinal lymph nodes diagnosis. This work relates the CHLS first three years' experience in terms of EEB practical use as a new diagnostic tool in this field.
  
  
  METHODS
  Retrospective study of consecutive cases patients having undergone endobronchial ultrasound from November 2008 till June 2011 in the CHLS.
  
  
  RESULTS
  On 65 endobronchial ultrasound, general anesthesia was practiced in 89 % of the cases, with a good tolerance in 81 % of the cases. In 77 % cases, EEB allowed diagnosis and avoided mediastinoscopy in 60.5 % of the cases. The respective sensibility, specificity, positive and negative predictive values were 74 %, 100 %, 100 % and 48 %.
  
  
  CONCLUSIONS
  These data, reflect of a novice team experience, illustrate the results obtained in the current practice in terms of etiologic diagnosis. Endobronchial ultrasound seems destined to a bright future but requires the development of dedicated centers allowing pulmonologists training and specialized pathologists in this field.
