Operative endoscopy of the airway with the old-fashioned esophageal dilators.

Bronchial dilation is usually required to treat a number of disorders; the most frequent are complications after airway surgery, including lung transplantation, stenosis after radiotherapy, and compression by an extraluminal mass. The procedure is performed by forcing the tip of a rigid bronchoscope through the stenosis using barrels of increasing size; however, when there is a clear discrepancy between the caliber of the rigid instrument and the stenosis, the first step may be difficult. In such cases, we have successfully employed two types of old-fashioned esophageal dilators rescued from the armamentarium of our endoscopy unit.
