Outcomes of Endoscopic Closure of Respiratory Esophageal Fistula in Children Using the Esophageal Approach: A Case Series

Repository-esophageal fistula (REF) in children includes congenital or acquired tracheoesophageal fistula (TEF) and pleuro-esophageal fistula (PEF). TEF is a well-known congenital anomaly that is managed surgically. Recurrent tracheoesophageal fistula (rTEF) occurring after surgical repair of TEF is not an uncommon complication and most of the time requires repeat surgery. The aim of this paper is to report the outcomes of endoscopic closure of REF in children in Oman. This is a retrospective case series describing the endoscopic closure of REF in children in the Royal Hospital (RH), Oman. Five cases were identified with one of them having acquired PEF while the rest had rTEF. All children had esophageal endoscopic closure of the esophageal fistula using endoclips, cauterization, and glue injection. The patient who had PEF had successful closure of the fistula and only one out of four with rTEF had successful endoscopic closure. Esophageal endoscopic approach is unsatisfactory in the closure of rTEF but could be effective in the closure of inflammatory PEF. An esophageal approach for the closure of rTEF may need to be consolidated with simultaneous bronchoscopic closure.
