Novel technique to prevent central airway blood flooding during transbronchial cryobiopsy

Transbronchial cryobiopsy is useful for diagnosing diffuse parenchymal lung diseases, as well as localized lung lesions (1-5). It provides larger and higher quality specimens without crush artifacts compared to those obtained by conventional biopsy forceps (6). As transbronchial cryobiopsy samples tend to be larger, the risk of bleeding from the biopsy site is higher than that associated with forceps biopsy.
