Abstrakt:	Objective: To evaluate the efficacy and safety of tranbronchial cryobiopsy ( TBCB) with 1.9-mm and 1.1-mm cryoprobes in patients with peripheral pulmonary lesions (PPLs). Material and Methods: We analyzed 34 patients (mean age 60 years) with PPLs who underwent bronchoscopy with TBCB. Mean lesion size was 31.5 mm, upper lobe localization was predominant (47% of cases). CT signs of appropriate bronchus were identified in 79% (27/34) of cases. Manual branch tracking and virtual bronchoscopy (VB) were performed pre-procedurally, and radial endobronchial ultrasonography (rEBUS) was performed during bronchoscopy for accurate positioning of PPLs. TBCB was performed using 1.9-mm ( n =19) or 1.1-mm ( n =15) cryoprobes without fluoroscopic guidance. Incidence and severity of bleeding and pneumothorax were evaluated in all patients. Results: Total efficacy of TBCB was 76.5% (26/34): 78.9% (15/19) for 1.9-mm cryoprobe and 73.3% (11/15) for 1.1-mm cryoprobe ( p =0.702). Efficacy depended on the presence of CT signs of bronchus (presence - 94%, absence 14.3%, p <0.001) and PPL size (94% for PPL >30 mm and 58.8% for PPL <30 mm, p =0.016). Central probe position during rEBUS was associated with 94.7% diagnostic efficacy (18/19), adjacent probe position - 72.7% (8/11) ( p =0.088). Bleeding grade 3 (Nasville) occurred in 5.8% (2/34) of cases, and no pneumothorax was observed. Conclusion: TBCB is an effective and safe diagnostic method for PPLs.
