[Transbronchial cryobiopsies : a minimally invasive tool for the diagnosis of interstitial lung disease]

The diagnosis of interstitial lung disease (ILD) is challenging and relies on a multidisciplinary discussion involving clinical, radiological and sometimes histological features. Bronchoscopic lung cryobiopsies have emerged as a new minimally invasive method of lung sampling and an alternative to surgical lung biopsies. A good diagnostic performance and excellent safety profile make it an interesting and worthful procedure which could decrease the number of patients without proper diagnosis and treatment. There is a need for further studies to standardize the technique in expert centers and to establish its role in the diagnostic work-up of ILD.
