In patients with interstitial lung disease (ILD) with inconsistent clinical and radiological features, establishing a reliable diagnosis of ILD requires a surgical lung biopsy
Transbronchial cryobiopsy is a minimally invasive, rapid, safe technique, and with histologic diagnostic yields, for ILD, typically exceeding 70 -80% .
The aim of this study is to compare and analyze the diagnostic yield, for ILD, and complications following SLB and TC
Methods. The investigators designed a descriptive, comparative and cross-sectional study in patients with ILD, in which SLB and CT will be performed in the same surgical stage, as diagnostic tests.
This study will be conducted from January 2018 to January 2019. Surgical lung biopsy and TC will be performed in the same surgical stage in all patients, under general anesthesia and mechanical ventilation. First TC will be performed by a pulmonologist, sequentially a thoracic surgeon will carry out a SLB.
The samples obtained will be analyzed by different pathologist to compare both techniques in terms of histologic features.
Diagnostic yield, postoperative complications, comorbidities and lenght of stay will be analyzed and compared following these procedures.
