Prospective analysis of 1,235 transbronchial lung biopsies in lung transplant recipients

Objective:. Fiber-optic bronchoscopy with multiple transbronchial lung biopsies (TBB) is the gold standard of evaluation of the pulmonary allograft post-lung transplantation (LT). However controversy exists regarding the need for surveillance procedures and number. of biopsy specimens required for satisfactory yield. The potential morbidity in obtaining multiple TBB specimens remains poorly described. We report the largest series of TBB in LT recipients to date, highlighting the occurrence of acute rejection and infection for surveillance and diagnostic procedures. The safety of TBB is analyzed and a biopsy schedule proposed
