title: Management of symptomatic congenital tracheal stenosis in neonates and infants by slide tracheoplasty: a 7-year single institution experience.
abstract: OBJECTIVE
  Congenital tracheal stenosis (CTS) is rare. When it presents early in life, its management can be challenging. Of the surgical techniques that have been devised to correct long-segment CTS, slide tracheoplasty (ST) appears to be superior. We present our 7-year-experience of ST for the treatment of symptomatic CTS in neonates and infants.
  
  
  METHODS
  The hospital records of all 14 neonates and infants who underwent ST between 2001 and 2008 at our hospital were retrieved. Patient characteristics, trachea morphology, co-existing anomalies, operative procedures, techniques, outcomes and clinical courses were reviewed.
  
  
  RESULTS
  Patients underwent ST at age 4 days to 22 months (median: 2.4 months). Five (36%) required intermittent ventilator support prior to surgery. All ST was done under cardiopulmonary bypass. The associated cardiovascular anomalies in 10 infants (71%) were also corrected at the same operation. All survived the initial surgical procedures. The in-hospital mortality for the group was 14.3%. The median periods of postoperative intensive care unit and hospital stay of the 12 children, who were successfully extubated within 7 postoperative days, were 9 days (range: 6-28 days) and 28 days (range: 14-375 days), respectively. Follow-up of all 12 midterm survivors was complete, ranging from 5 months to 5.6 years (median: 40 months). A total of four patients had been found to have tracheobronchial malacia postoperatively and were managed with stenting. Of the remaining 10 survivors who had no residual or recurrent airway problems, and no cardiovascular residuum or sequela, two had gross developmental delay.
  
  
  CONCLUSIONS
  In the management of symptomatic infants with CTS, our limited experience suggests that meticulously performed ST together with vigilant pre- and postoperative care can provide satisfactory short and midterm solution to the airway problem. Some incidental residual clinical problems appear to be unavoidable.
