Tracheobronchial stenting can aid in the management of pediatric airway problems. We reviewed our experience to determine the role of endoscopic airway stents in children.Sixteen children (Age range: 10 days- 19 years) underwent 28 tracheobronchial stents in the period 1991-2006. The stent type chosen depended on patient age and location. All procedures were done under general anesthesia with bronchoscopy. The following features have been taken into account: etiology, obstruction diagnosis, stent type, localization,,associated anomalies, complications, results, and time of follow-up.Etiology of the tracheobronchial obstruction included tracheobronchiomalacia in 13 patients (81.3%), tracheal stenosis in 2 (12.5%) and glotic stenosis in one case (6.2%). The stent used were 15 Palmaz (53.5%), 7 Dumon (25%), 4 Montgomey (14.5%), 1 Poliflex (3.5%) and one Dynamic stent (3.5%). More than one stent were undertaken in seven cases (43.7%). 16 patients had tracheal stents, 11 children had bronchial stent and one infant a carinal stent. Five complications are reported (two patients developed granulation tissue, two stents migrated, and a child presented a left lung atelectasis) and five patients died (only one case related to tracheobronchial stenting). Results have been satisfactory in 14 patients (87.5%) and the mean time of follow-up has been two years and ten months (range 2 months- 12 years and 6 months).The tracheobronchial stenting in children may represent a valid treatment option for many sick children in particular circumstances. The long-term outcome remains uncertain but the medium-term outlook is encouraging. |
