Esophageal Atresia Masterclass

Post-operative leak management in esophageal atresia repair follows a stratified approach based on leak severity and patient stability. Most small to moderate contained leaks resolve with observation alone, requiring intervention only when complicated by inadequately drained pneumothorax or hemodynamic instability [e13505-c1, e13505-c2]. Conservative adjuncts include saliva suppression with botulinum toxin or glycopyrrolate [e13505-c3, e13505-c4]. For refractory leaks, endoscopic vacuum closure (endo-bag) — a sponge-covered NG tube connected to suction — promotes granulation and accelerates healing, with device exchanges every 4-5 days demonstrating immediate leak closure on contrast studies [e13505-c6, e13505-c7, e13505-c8, e13505-c9]. This technique proves particularly effective for external cervical leaks and non-healing fistulae . Surgical re-anastomosis remains an option for deteriorating patients with large leaks, occasionally yielding excellent outcomes without subsequent stricture [e13505-c12, e13505-c15]. Stricture surveillance intensifies after any leak, as stenosis risk increases significantly . When antegrade endoscopy fails, retrograde dilation via gastrostomy provides alternative access .
