Esophageal duplication cysts are unusual malformations. We report the case of a 6-months-old boy, known with a prenatal mediastinal cyst. Postnatal workup showed a non-communicant compressive cyst bound to the lower third of the native esophagus compatible with an esophageal duplication.
It was surrounded by the aortic arch and the left hilum making the access difficult from either side by thoracoscopy or thoracotomy.
He underwent its removal by transhiatal laparoscopy using the technique we have previously described for esophageal removal. Pathology confirmed an esophageal duplication. This appears to be the first case of laparoscopic removal of a thoracic esophageal duplication cyst in a child.
