Brief Summary:
To proof the feasibility and safety of EBUS guided transbronchial cryo biopsies in peripheral lung lesions

Condition or disease Intervention/treatment Phase
Yield of Cryo Biopsy in Lung Cancer Solitary Pulmonary Nodule Procedure: Cryo biopsy Not Applicable

Detailed Description:

Solitary pulmonary nodule are a diagnostic dilemma. Nowadays not only the basic tissue diagnosis is necessary, molecular signals are state of the art. Therefore more tissue is necessary. With a cryoprobe the amount of tissue is increased compared to the classical forceps biopsy.

Until now, the use of the cryoprobe ism´t show in peripheral lung tissue.
