Quality of transbronchial biopsy with large forceps compared to cryobiopsy: a randomized controlled, single blinded live animal study.

ABSTRACT:

Background

Transbronchial forceps biopsy is the widely accepted modality for obtaining tissue specimens for the evaluation of unexplained lung parenchymal abnormalities. However, cryoprobe biopsy provides large specimen sizes and higher yield performance. Utilization of cryoprobe biopsy remains limited by its need to be performed under rigid bronchoscopy and subsequent required operator expertise. We evaluated whether a larger, 2.8 mm forceps could be utilized for parenchymal biopsies. A larger size would surrogate the cryoprobe's large sample size and forceps mechanism to obviate the need for rigid bronchoscopy and its requirement for removing the sample en bloc.

Methods

This prospective, randomized controlled, single-blinded porcine study compared a 1.9 mm cryoprobe, a 2.4
