A case series of 88 infants with suspected esophageal atresia (with or without a known tracheo-esophageal fistula) who underwent a laryngotracheobronchoscopy prior to surgical repair describes the findings of this procedure. New findings were discovered in one out of five of these babies. These included an unusual location of the fistula (e.g. sub-carinal or double fistula), laryngotracheal cleft, vallecular cyst, and previously unsuspected fistula. Prior knowledge of these anomalies could alter the surgical plan, thereby creating a case for routine preoperative laryngotracheobronchoscopy in these infants.
