[Conservative medical treatment of œso-tracheal fistula].

œso-tracheal fistulas are a pathological condition characterized by an abnormal communication between the tracheal tree and the esophagus. We here report a clinical case of œso-tracheal fistula due to the ingestion of a foreign body in order to highlight its etiopathogenesis, to evaluate our therapeutic approach and to do a literature review. The study involved a 15 year old patient admitted with dysphagia evolving over the last two months following the ingestion of a foreign body (a piece of bone).
