Efficacy and risk profile of self-expandable stents in the management of pediatric esophageal pathology.

Purpose: The purpose of this study was to evaluate the efficacy and risk profile of esophageal stents in the management of complicated pediatric esophageal disease.
Methods: An IRB-approved, single-center, retrospective review was performed on all pediatric patients (n = 13) who underwent esophageal stent placement (2005-2017). Demographic, perioperative, and outcome data were analyzed (p < 0.05).
Results: Forty-one stents were placed due to recalcitrant strictures (n = 36), perforations (n = 2), and/or fistulae (n = 3). Median age at initial stent placement was 23.8 months (range, 50 days to 16 years), and median stent duration was 36 days (range, 3-335). The recurrence rate for strictures after initial stent removal was 100%. Four (31%) children subsequently underwent definitive operative repair. There were 5 deaths, including 2 related to stent placement. Seventy-one percent of stents were associated with an adverse event, most commonly intraluminal migration (56%). Younger children experienced an increased risk for airway compression and retching (p = 0.010).
Conclusion: These data suggest that stents are associated with high complication rates and are not effective as definitive therapy for recalcitrant strictures in children. Although there may be a temporizing role for stents in selected patients, further refinements in stent technologies are needed to help manage this difficult patient population.
Level of Evidence: Level IV.
