Ice Capades Skating Around Current Practice of Cryobiopsy for ILD

Background: Transbronchial lung cryobiopsy (TBLC) has been proposed as a potentially safer alternative in the diagnosis of interstitial lung disease. The current practice of TBLC is unknown as most published data come from case reports, case series, and a few trials. The authors report the practice patterns of TBLC on the basis of survey responses. Methods: The authors created an anonymous online survey to assess how proceduralists evaluate patients, perform, and manage complications of TBLC. Surveys were distributed through social media and e-mail distribution lists from the American Association of Bronchology and Interventional Pulmonology and the Society of Advanced Bronchoscopists. Aggregated responses are reported as counts, percentages, and averages. Results: Surveys show significant variation in parameters providers use to assess appropriate patients for procedures, how specific aspects of TBLC are performed, and how complications and results are managed. Conclusion: This is the first and largest survey of providers describing the current large variation in the use of cryobiopsy for the evaluation of interstitial lung disease. The standardized practice is essential to understand the true diagnostic accuracy or rate of complications related to TBLC.
