Successful bronchoscopic balloon dilation of nonmalignant tracheobronchial obstruction without fluoroscopy.
OBJECTIVE
To evaluate the safety and efficacy of bronchoscopic balloon dilation (BBD) without fluoroscopy for relief of tracheobronchial obstruction.


METHODS
We performed a retrospective study of all adult patients who underwent BBD without fluoroscopy at the Tulane University Hospital and Clinic between July 1, 1997, and June 30, 2002.


RESULTS
Twenty-four patients (mean [+/- SD] age, 58 +/- 14 years; 80% men) underwent 59 BBD procedures without fluoroscopy for the following conditions: iatrogenic tracheal stenosis (80%); saber-sheath trachea (4%); bronchial stenosis resulting from lung transplantation (4%); sarcoidosis (4%); Wegener granulomatosis (4%); and idiopathic stenosis (4%). All BBD procedures were performed via a rigid bronchoscope (61%) or a flexible bronchoscope (39%) without fluoroscopy. BBD was often combined with mechanical debridement (64%), stent placement (47%), or laser photoresection (19%), although in 26% of cases BBD was the only intervention. During the 59 procedures, 71 different balloon catheters were deployed a total of 112 times (deployment was defined as any use of balloon dilation in a different location, for a different purpose, or to a different inflation diameter). These 112 deployments were performed for primary dilation (49%), dilation prior to stent placement (28%), and stent seating (22%). Improvement in stenosis was achieved immediately postprocedure in all 59 procedures (100%). One balloon ruptured during inflation without clinically significant effect, and no other complications occurred.


CONCLUSIONS
BBD without fluoroscopy for the relief of nonmalignant tracheobronchial obstruction can be safely performed through a rigid or flexible bronchoscope. It can be used alone or as an adjunct to other therapeutic modalities. In this series, 100% of airway obstructions were improved, and there were no clinically significant complications. BBD of a tracheobronchial obstruction without fluoroscopy is safe, efficacious, and cost-effective.
