简要总结
Forty-nine patients (98%) could undergo both forceps biopsy and cryobiopsy. Forceps biopsy, cryobiopsy and their combination provided specimens with specific pathological findings in 54%, 62%, and 74%, respectively. The size of cryobiopsy specimens was significantly larger. Bleeding occurred in most cases, but no serious adverse events occurred. Cryobiopsy using an ultrathin bronchoscope is feasible and acceptably safe, and plays a complementary role to forceps biopsy in terms of diagnostic yield.
