Transbronchial Cryobiopsy in Diffuse Parenchymal Lung Diseases in a Community Medical Center

Summary

Background:

Transbronchial cryobiopsy (TBC) has recently emerged for the assessment of diffuse parenchymal lung disease (DPLD) as a less invasive procedure than surgical lung biopsy. The diagnostic usefulness and safety of TBC is still controversial.

Objectives:

To evaluate the safety and diagnostic yield of TBC in a peripheral community medical center.

Methods:

We retrospectively reviewed the charts of all patients with DPLD who underwent TBC from January 2015 to January 2020.

Results:

The study comprised 97 patients. Three samples were taken from each patient with an average diameter of 0.59 cm. The histologic diagnostic yield was 54% (52 of 97 procedures). The most frequent histopathologic diagnoses were usual interstitial pneumonia in 13 patients (13%). Bleeding was observed in 19 cases (19%) and only one patient (1%) had severe bleeding. Pneumothorax developed in seven patients (7%) and one patient (1%) suffered from Interstitial lung disease exacerbation.

Conclusions:

TBC was found to be safe; however, the diagnostic yield was rather low compared to other studies, which emphasizes the need for interstitial lung disease centers with expert in this field.
