Aerodigestive Sequelae and Triple Endoscopy after Congenital Tracheoesophageal Fistula Repair in Children

Children post-tracheoesophageal fistula (TEF) repair may present with chronic respiratory and gastrointestinal symptoms that can affect quality of life. Objective To identify factors associated with positive findings on triple endoscopy following neonatal TEF repair. Study Design Case series with retrospective review of patients. Setting Tertiary care center aerodigestive program. Methods Children with neonatally repaired congenital TEF who had a triple endoscopy between 2011 and 2022 were reviewed. The presence of chronic cough, recurrent pulmonary infections, lipid-laden macrophages (LLM), and airway and esophageal anomalies were among the variables analyzed. Chi-square and Kruskal-Wallis univariate analysis was performed. Results The mean age was 4.28 +/- 4.65 years old, and the most common type of TEF repaired was type C (78%). Within our cohort, 87% of patients had GERD, 60% of patients had prior esophageal dilations, and 84% of patients had tracheomalacia. Thirty-one (46.3%) patients had laryngeal cleft, of which 77.4% had a history of prior esophageal dilations (P = .01). Twenty-one (33.9%) patients had tracheal diverticulum on bronchoscopy, which was associated with chronic cough, stridor, and coughing with feeds. Patients with positive LLM on BAL were associated with presentation of chronic cough and stridor (P = .03). Recurrent TEF was associated with chronic cough. Subglottic stenosis was associated with a history of prolonged intubation (P < .05). Conclusion Chronic cough was frequently reported and associated with tracheal diverticulum, recurrent TEF, and positive LLM findings on triple endoscopy in patients after congenital TEF repair. Patients presenting with chronic cough and stridor following congenital TEF repair may benefit from a multidisciplinary evaluation.
