Study Summary

Lung transplant recipients undergo bronchoscopy with biopsies for clinical indications and for surveillance in the diagnosis of acute rejection using standard transbronchial forceps. It is recognized that standard forceps biopsies underestimate the presence or degree of airway rejection due to crush artifact and sample size. Transbronchial cryobiopsies have been shown in the literature to provide larger samples without crush artifact in a safe fashion in lung cancer patients. The aim of this study is to determine if transbronchial cryobiopsy is superior to standard transbronchial forceps biopsies in regards to sample size, architecture and the diagnosis of early rejection in lung transplant recipients which if discovered earlier may improve survival.

Primary Outcome

Direct measurements of pathologic specimens from the forceps and cryoprobe will be compared. In addition, amount of crush artifact will alse be directly measured and compared utilizing pathology software which measures area of viable tissue.
