Surgical intervention strategies for congenital tracheal stenosis associated with a tracheal bronchus based on the location of stenosis.

PURPOSE

The aim of this study was to determine the appropriate surgical intervention strategies for congenital tracheal stenosis (CTS) associated with a tracheal bronchus based on the location of stenosis.

METHODS

The medical records of 13 pediatric patients with CTS associated with a tracheal bronchus at a single institution between January 2006 and December 2015 were retrospectively reviewed.

RESULTS

Type 1: tracheal stenosis above the right upper lobe bronchus (RULB) (n = 1). One patient underwent slide tracheoplasty and was successfully extubated. Type 2: tracheal stenosis below the RULB (n = 7). Tracheal end-to-end anastomosis was performed before 2014, and one patient failed to extubate. Posterior-anterior slide tracheoplasty was performed since 2014, and all three patients were successfully extubated. Type 3: tracheal stenosis above the RULB to the carina (n = 5). One patient underwent posterior-anterior slide tracheoplasty and was successfully extubated. Two patients with left-right slide tracheoplasty and another two patients with tracheal end-to-end anastomosis for the stenosis below the RULB could not be extubated.

CONCLUSION

Tracheal end-to-end anastomosis or slide tracheoplasty can be selected for tracheal stenosis above the RULB according to the length of stenosis. Posterior-anterior slide tracheoplasty appears feasible for tracheal stenosis below the RULB or above the RULB to the carina.
