[Trial of fluoroscopy-guided transbronchial lung biopsy for the diagnosis of lung tumors].

As computed tomography( CT) technology has improved, chest CT has been adopted as a means to survey masses. We now see many cases of pulmonary small nodules or ground-glass opacities( GGO). Herein, we report our investigation of a new procedure, fluoroscopy-guided transbronchial lung biopsy (TBLB), for the diagnosis of such lesions. From 2009 through 2010, we examined 25 patients with pulmonary small nodules or GGO. Of these, 76% were successfully examined by conventional methods versus 62% by TBLB.
