This study prospectively compared the quantity and quality of samples collected from swine mediastinal lymph nodes using TBNA and those collected from human mediastinal/hilar lymph node lesions using EBUS-TBNA at two suction pressure levels, i.e., -20kPa and -80kPa, to determine the suction pressure that yielded samples of the best quantity and quality.
Efficacy
Diagnostic tissue (the area of a pathological sample useful in disease diagnosis; a parameter of sample quantity) and damaged area in tissue (percentage of damaged tissue area in the total tissue area; a parameter of sample quality) were compared as primary endpoints between the two groups.

Male and Female
1.Examination with bronchoscope is necessary for the diagnosis of the pulmonary lesion regardless of the participation of this study, is the case using a supersonic wave device (EBUS) and the guide sheath (GS) at the time of inspection.
2.The case that a document agreement by the free will of the person was provided on enough understanding after having received enough explanation on participating of this study
3.It is a case younger than 90 years 20 years old or older at the time of the agreement acquisition
4.Longer axis 2cm or less of the target lesion in the chest CT
5.The case that thin slice CT less than slice thickness 2mm is photographed in examination with bronchoscope precordial region CT
1.A case with pneumothorax that is clear before examination.
2.The case that merges respiratory failure (PaO2 <60torr)
3.It is a case of blood pressure vital measurement just before the examination with bronchoscope start for the shrinkage period
4.In addition, the case that a manager for study, a study partaker judged to be inappropriate.
