摘要
Objective Endoscopic balloon dilation (EBD) is an inviting, noninvasive option to manage pediatric subglottic stenosis that could preclude the need for tracheostomy and/or laryngeal-tracheal reconstruction (LTR). However, treatment outcomes and patient selection criteria are not well described. %26lt;br%26gt;Data Sources MEDLINE, EMBASE, and the Cochrane databases were systematically searched using multiple search terms. %26lt;br%26gt;Review Methods A systematic review of pediatric EBD was performed and then reported in compliance with PRISMA principles. Inclusion criteria consisted of a sample size of 5 or greater, pediatric patients, and primary EBD without adjuvant procedures. Meta-analysis was performed with random effects modeling and pooled data regression. %26lt;br%26gt;Results After systematic database search and detailed review, 7 studies were included in the final data set with 150 total subjects. All studies were case series (level 4 evidence). The mean sample size was 20 subjects (range, 5-44), and the grand mean age was 2.2 years (range, 2.2-60 months). The random effects model estimate of the overall treatment success (avoidance of tracheostomy or LTR) was 65.3% (k = 6 studies, 95% confidence interval [CI] = 60.1%-70.6%, P %26lt; .001, Q test for heterogeneity = 3.98, P = .552, I-2 = 0%). Follow-up was inconsistently reported but averaged 4.6 months (range, 0.25-12.5 months). Only 1 study reported significant complications (1 death, 2 tracheal lacerations). Pooled data multivariate regression indicated that increasing Cotton-Meyers grade was associated with decreased odds of success (odds ratio = 0.198, 95% CI = 0.0451-0.870, P = .032). Funnel plot analysis suggested the possibility of publication bias. %26lt;br%26gt;Conclusions EBD is successful in most patients over short-term follow-up. The reported complication rates are low. Increasing severity of subglottic stenosis increases the odds of treatment failure.
