Is tracheal stenosis caused by percutaneous tracheostomy different from that by surgical tracheostomy?
STUDY OBJECTIVE: To compare the surgical findings of tracheal stenosis caused by percutaneous tracheostomy (PCT) and surgical tracheostomy (SGT). DESIGN AND SETTING: A combined prospective (from 2001 to 2003) and retrospective (from 1993 to 2001) observational study of the patients undergoing tracheal resection and reconstruction for treatment of tracheal stenosis following PCT or SGT in a national referral center for thoracic surgery in the United Kingdom. PATIENTS AND MEASUREMENTS: We studied 29 patients presenting with symptomatic tracheal stenosis requiring tracheal reconstruction. We recorded the demographic data, duration of mechanical ventilation, onset of tracheal stenosis after decannulation, and type of tracheostomy (PCT or SGT) from referral notes. Tracheal reconstruction was preceded by rigid bronchoscopy, through which the distance of the superior level of stenosis to the vocal cords, and the length and the diameter of stenosis were measured. The type of surgical technique
