Pneumothorax following transbronchial biopsy. Low diagnostic yield with routine chest roentgenograms.
A chest roentgenogram is commonly obtained after a transbronchial biopsy to exclude a pneumothorax. We hypothesized that these routine chest roentgenograms rarely demonstrate a pneumothorax in patients who have neither symptoms nor fluoroscopic findings of lung collapse. To test this hypothesis, we studied 305 consecutive patients undergoing bronchoscopy with fluoroscopically guided TBB. No patient without symptoms and fluoroscopic findings suggesting lung collapse had a pneumothorax demonstrated on the post-biopsy chest roentgenogram. At the University of Virginia, routine chest roentgenograms failed to demonstrate a single unsuspected pneumothorax among all patients undergoing TBB during a period of nearly six years. Given this low incidence of unsuspected pneumothorax, we conclude that routine chest roentgenograms have a low diagnostic yield and may not be necessary in all patients after fluoroscopically guided TBB.
