Repair of congenital H-type tracheoesophageal fistula by electrocautery

Abstract

Background: Congenital H-type tracheoesophageal fistula is a rare type of congenital tracheoesophageal malformation. In this malformation, the esophagus remains unobstructed, complicating and delaying the diagnosis. We present our experience with three infants with congenital H-type tracheoesophageal fistula who were initially treated by a minimally invasive approach via endoscopy with electrocautery. Results: Two of the three patients ultimately required a surgical procedure after failure to close the fistula via electrocautery despite multiple attempts over several months. One of the three patients was successfully treated via electrocautery after the second procedure. Conclusions: In our center, three infants with congenital H-type tracheoesophageal fistula were initially treated endoscopically with electrocautery. Two out of the three ultimately required a surgical procedure. If considering endoscopy with electrocautery, providers and families should recognize that the procedure may need to be performed several times before the fistula is successfully closed. Additionally, failed attempts may put patients at risk for complications such as respiratory decompensation, pneumonia and poor growth and may prolong hospitalization.
