About this trial

The goal of this clinical trial is to evaluate which biopsy collection method helps to better diagnose rejection and relevant pathologic findings in lung transplant recipients. The main questions it aims to answer are:

Does the 1.1 mm cryoprobe or the biopsy forceps provide better quality samples of lung tissue for detecting rejection in transplant recipients?

How much tissue is adequate for lung transplant 1.1 mm cryobiopsy samples as compared to biopsy forceps?

Which samples received by the pathologist did they find they were most confident to exclude rejection, based on their satisfaction with the samples?

Which collection method has the least amount of procedural time?

Researchers will compare lung tissue samples obtained using a 1.1mm cryoprobe and a biopsy forceps during the lung transplant.

Participants will:

Be randomly assigned to receive either the cryoprobe or biopsy forceps collection method at the time of biopsy.

Assessed for any adverse events following the biopsy for up to 30 days after transplant.

Eligibility criteria

Qualifiers

Male and female lung transplant recipients age >18 at the time of informed consent

Patients clinically meet indication for post-transplant lung biopsy or planned routine surveillance and have been scheduled for bronchoscopy with transbronchial biopsy.

Disqualifiers

Patients with known bleeding diathesis

Platelet count <50,000 per μL within 14 days of the biopsy procedure
