<qa>  What is the first time ENB lung biopsy is documented in Canada?There have been no studies directly comparing ENB to TTNB, either retrospectively or prospectively. Initial systematic reviews demonstrate that ENB may have a slightly lower diagnostic yield relative to TTNB. Selection bias and low study quality may have resulted in an underestimation of the true diagnostic yield associated with ENB. The literature also confirms that ENB has a significantly better safety profile as compared to TTNB. As such, a prospective comparison between the two techniques is mandated. This Phase II pilot feasibility trial will utilize randomized methodology to gather the preliminary data that is required for the successful completion of a Phase III randomized controlled trial to compare lung biopsy with ENB verses TTNB. This study will also be the first time ENB lung biopsy is documented in Canada.
