Is routine chest radiography after transbronchial biopsy necessary?: A prospective study of 350 cases.

Background And Study Objective: Pneumothorax following flexible bronchoscopy (FB) with transbronchial biopsy (TBB) occurs in 1 to 6% of cases. Routine chest radiography (CXR) following TBB is therefore requested by most pulmonologists in an attempt to detect complications, particularly pneumothorax. The objective of this study was to determine if routine CXR after bronchoscopy and TBB is necessary.
