[Respiratory insufficiency due to duplications of the oesophagus].

Duplications of the oesophagus are uncommon congenital malformations with possible occurrence in any part of the gastrointestinal tract. The duplications may be cysts, diverticula or tubular-shaped. Cysts may even occur further away from the gastrointestinal tract, not necessarily having contact with it. I present a patient case, in which a 13-month-old child was brought to the emergency room due to gradually increasing dyspnea. The child made a full recovery after the surgical procedure.
