Value of rapid on‐site evaluation combined with interventional pulmonology techniques in the diagnosis of pulmonary cryptococcosis

Abstract Objectives The aim of this study is to evaluate the diagnostic value of rapid on‐site evaluation (ROSE) combined with computed tomography‐guided percutaneous needle biopsy (CT‐PNB) or radial endobronchial ultrasound‐guided transbronchial lung biopsy (EBUS‐TBLB) for pulmonary cryptococcosis (PC). Methods Clinical data of 33 patients diagnosed with PC at the Third Affiliated Hospital of Soochow University between February 2018 and June 2023 were retrospectively analysed. Patients were divided into the CT‐PNB and EBUS‐TBLB groups based on the intervention method, and the diagnostic positivity rate and incidence of complications were compared between the two groups. Results Compared with the final diagnosis, the positive diagnostic rates of ROSE, histopathology and serum CrAg of all patients were 81.8% (27/33), 72.7% (24/33) and 63.6% (21/33), respectively. The average turnaround times of the three methods were 0.1 (0.1–0.2) h, 96.0 (48.0–120.0) h and 7.8 (4.5–13.6) h, respectively (P
