Primary Outcome Measures
NameTimeMethod
Diagnostic yield of transbronchial lung biopsy (TBLB)24 months

Comparing those TBLB obtained by cryoprobes versus conventional forceps (number of diagnosis with each technique).

Secondary Outcome Measures
NameTimeMethod
Safety related to the procedure of the TBLB obtained by cryoprobe compared with conventional forceps assessed by control of bleeding.24 months

Control of bleeding during procedure.

Histological quality of samples as defined the presence of alveolar units in each sample. Composite measure.24 months

The quality of samples are defined by the size, presence of artifacts and presence of alveolar units in each sample.

Safety related to the procedure of the TBLB obtained by cryoprobe compared with conventional forceps assessed by chest radiography.24 months

Chest radiography after TBLB.
