- Original description
This study is a prospective observational non-randomized clinical trial where all the participitants undergo the same procedure and every participitant's samples are compared to each other. The investigators conduct EBUS TBNA and EBUS TBMCB on all the study participants.The cryobiopsy samples are numbered to evaluate the number of biopsies needed to reach a definite diagnosis and to assess the added value of every sample taken from the same participitant. Every participitant's own samples are compared to each other and added value of EBUS TBMCB is defined as the difference in diagnostic yield between the EBUS TBNA alone and the combination of EBUS TBNA with EBUS TBMCB. Diagnostic yield is defined as the efficacy of the investigation module in reaching a definite diagnosis (percentage of cases with a definite diagnosis).Read full original descriptionShow less

Follow up four weeks after the procedure to assess the risk for postoperative complications.
