INTRODUCTION: Transbronchial lung cryobiopsy (TBCB) has emerged as a diagnostic alternative to surgical lung biopsy mostly in interstitial lung disease. Despite its less invasive nature and reported higher diagnostic yield, some associated complications have been described, such as pneumothorax. Moreover, a comparison between TBCB and transbronchial forceps biopsy is seldomly made. The aim of the present study is to evaluate the incidence of pneumothorax following TBFB and TBCB and the need for pleural drainage.
METHODS: Retrospective study of patients who underwent transbronchial forceps biopsy or transbronchial lung cryobiopsy, specifically those who developed postoperative pneumothorax.
RESULTS: A total of 181 transbronchial lung biopsies were performed. Sixty three (35%) were TBFB and 118 (65%) were TBCB. Three patients in the TBFB group (5%) presented postoperative pneumothorax, while 16 patients (14%) presented pneumothorax in the TBCB group (p 0,051). The univariate analysis revealed a statistically significant association between the preoperative diagnosis of fibrosis and a higher risk of postoperative pneumothorax following TBCB (p 0.027), while other variables did not yield a statistical significance.
CONCLUSION: Even though more high-volume comparative studies are needed, this paper highlights the relevance of pneumothorax following TBCB. This derives in a strong need for clearly standardized procedure protocols for TBCB and careful evaluation of its complications vs. its definitive diagnostic yields.
