Résumé
Surgical lung biopsy (SLB) is the gold standard to aid diagnosis of interstitial lung disease (ILD). Complication rates are restrictive as routine approach for all patients with ILD. Transbronchial lung cryobiopsy (TBLC) is presumed to be a safe, less invasive alternative to assist multidisciplinary discussions regarding the diagnosis of ILD. Varying practice patterns and lack of consistent guidelines prohibit wide support of this technique. The purpose of this study was to evaluate safety and diagnostic yield of TBLC, with highlight of distinct technical features, in ILD. Retrospective study of patients with ILD on the basis of high-resolution chest computed tomography who underwent TBLC. Of 121 TBLC, 40 patients (mean age, 57.2±13 y; 28 men) with ILD were referred for biopsy. Procedures were performed in endoscopy suite (60%) or operating room by using 1.9-mm cryoprobe. Biopsies were performed in 2 lobes with at least 3 to 5 specimens >5 mm in diameter. The average diameter and area of specimens were 5.7±2 mm and 40±2 mm, respectively. The most common diagnosis was nonspecific interstitial pneumonitis; usual interstitial pneumonia was diagnosed in 1 patient. Of 6 nondiagnostic specimens, 2 underwent SLB with subsequent diagnoses. Final histopathologic diagnostic rate was 85%. Bleeding was the most frequent complication. We provided a detailed description of our TLBC technique and highlighted areas of similarity and differences among comparative studies and attest that TBLC is a safe alternative to SLB in the diagnosis of ILD. Our data also indicated the tendency for moderate-to-severe bleeding occurred more in the endoscopy suite.

Of 121 TBLC, 40 patients (mean age, 57.2±13 y; 28 men) with ILD were referred for biopsy. Procedures were performed in endoscopy suite (60%) or operating room by using 1.9-mm cryoprobe.

CONCLUSIONS
We provided a detailed description of our TLBC technique and highlighted areas of similarity and differences among comparative studies and attest that TBLC is a safe alternative to SLB in the diagnosis of ILD. Our data also indicated the tendency for moderate-to-severe bleeding occurred more in the endoscopy suite.
