Kluth Type IIIb 6 Esophageal Atresia: Diagnostic Dilemma and Pitfalls of Using Infant Feeding Tube.

We describe three male neonates where infant feeding tube (IFT) passed 18-20 cm in the upper esophageal pouch. A blunt-tipped red rubber catheter confirmed esophageal atresia (EA) with long upper pouch in all three cases. Definitive management revealed EA with tracheoesophageal fistula and long overlapping upper esophageal pouch consistent with Kluth Type IIIb6 variant in two patients. Importance of using red rubber catheter at the pediatric practice instead of IFT is stressed.
