Estimated Enrollment: 30
Study Start Date: April 2010
Estimated Study Completion Date: December 2010
Estimated Primary Completion Date: December 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Cryo biospy Procedure: Cryo biopsy
Cryoprobe, Erbe Company
Other Name: Cryo biopsy probe 20416-032, ERBE company, Germany

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.
