Pediatric tracheal surgery.

BACKGROUND

Pediatric tracheal procedures are uncommon. We reviewed our experience to clarify management and results.

METHODS

Retrospective single-institution review of pediatric tracheal operations, 1978 to 2001.

RESULTS

One hundred sixteen children were evaluated, mean age 10.4 years (10 days to 18 years). Tracheal pathology was postintubation stenosis (n = 72; 62%), congenital stenosis (n = 23; 20%), neoplasm (n = 8; 7%), tracheomalacia (n = 7; 6%), and trauma (n = 6; 5%). Twenty-nine patients had previous tracheal operations. Thirty-six patients received only a minor procedure. Eighty patients had major operations: tracheal resection (n = 46; 58%), laryngotracheal resection (n = 22; 28%), slide tracheoplasty (n = 7; 9%), and carinal resection (n = 5; 6%). The mean length of airway resected was 3.3 cm (1.5 to 6 cm), which represented 30% of the entire trachea. Twenty-eight patients (35%) had complications. These included tracheomalacia (n = 3), recurrent nerve injury (n = 3), laryngeal edema requiring intubation (n = 2), stroke (n = 1), esophageal leak (n = 1), and lobar collapse (n = 1). Nineteen patients had anastomotic failure: severe restenosis (n = 6), mild restenosis (n = 9), dehiscence (n = 2), dehiscence with tracheoesophageal fistula (n = 1), and tracheoinnominate fistula (n = 1). Two children died (2.5%). Complications were more frequent in children less than 7 years of age (p = 0.05) and after previous operations (p = 0.02). Longer fractions of tracheal resection (> 30%) were more likely to result in anastomotic failure (p = 0.0005). Sixty-four (80%) patients achieved a stable airway free of any airway appliance. All patients with neoplasms are alive.

CONCLUSIONS

The principles of adult tracheal operations are directly applicable to children and usually lead to a stable, satisfactory airway. Children tolerate anastomotic tension less well than adults; resections more than 30% have a substantial failure rate.
