Esophageal atresia type III? Intraoperative surprise and different approaches.

A newborn was referred due to clinical and radiological suspicion of esophageal atresia (EA) type III. Surgery revealed an esophagus without evident interruptions; however, intraoperative advancement of the nasogastric tube was unsuccessful, and the distal esophagus inflated with each ventilation, indicating the presence of a distal fistula. An intraoperative esophago-tracheobronchoscopy showed a proximal esophageal pouch with a tiny tracheoesophageal fistula and a large distal tracheoesophageal fistula. The esophageal ends were blind but overlapping, with no external discontinuity observed. With the diagnosis of Krediet type IIIc2 esophageal atresia, we performed a meticulous esophago-tracheal dissection, distal fistula closure, and end-to-end anastomosis. Due to hemodynamic instability, the proximal fistula was closed two weeks later via cervicotomy without incidents.
