Gastro-Esophageal Reflux in Esophageal Atresia Patients Remains a Challenge: Results from a Systematic Review and Meta-Analysis

Although international guidelines address the management of esophageal atresia (EA), the optimal approach to gastroesophageal reflux disease (GERD) in this population remains controversial. This systematic review and meta-analysis aims to clarify the current management of GERD in children after EA repair, reporting the prevalence of GERD, indications, and effectiveness of medical and surgical therapies.A systematic review was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines. A literature search was performed in MEDLINE, Cochrane Database, and Web of Science. Studies involving patients under 18 years old with GERD following EA repair were included. Data were extracted on incidence, diagnostic approach, medical and surgical management, and outcomes.Out of 1,612 articles, 49 (5,613 patients) were included. Reporting diagnostic modality, pH-impedance was most frequently used. The pooled GERD incidence was 36.7% overall and 58.1% in type A/B EA. Postoperative anti-reflux medication was reported in 88% of patients; 53.8% of children receiving medical therapy subsequently required further procedures (anti-reflux surgery [ARS], feeding stoma, or total esophago-gastric dissociation). ARS was more common in type A/B than in type C/D cohorts. Resolution of symptoms after ARS was reported in 74.5% of patients. Complications following ARS occurred in 28.3%, with a 14.9% rate of redo fundoplication, and the highest incidence occurred in infants < 6 months. The data on timing and type of ARS were heterogeneous.GERD affected over one-third of EA patients, with higher prevalence in types A and B. Although proton pump inhibitor therapy is common, a large proportion required ARS, with higher complication rates in smaller children. These findings highlight the need for standardized diagnostic criteria and multicenter prospective registries with long-term follow-up to clarify optimal timing and technique.
