Heterotopic Pancreas of the Esophagus Associated With a Rare Type of Esophageal Atresia

An infant with a rare type of esophageal/tracheal anomaly associated with heterotopic pancreas of the esophagus is herein reported. The upper pouch containing heterotopic pancreas reached 1.5 cm below the tracheal carina, and the distal esophagus connected to the trachea 2 cm above the tracheal carina and thus formed a partial duplication of the esophagus. Heterotopic pancreas of the esophagus is extremely rare, with only 7 cases previously reported. Here we report the combination of heterotopic pancreas and esophageal atresia with tracheoesophageal fistula.
