    Abstract:
    Tracheo-esophageal fistulas as a sequelae of esophageal atresia surgery are usually a severe complication whose correction requires an important surgical aggression, often with uncertain results. The possibility of treating this problem through the use of non-aggressive endoscopic methods has been described in medical literature over the last years, applying several products for occlusion with conflicting results in different publications. We present three cases of tracheo-esophageal fistulas, describing the technique of trans-tracheal endoscopic approach based on the novelty of employing a laryngeal mask which facilitates ventilation during the procedure, as well as the possibility to use endoscopic material of greater diameter. We comment on the different occlusion materials employed (Tissucol & Histoacryl) and the difficulties of their management. In one case two attempts of occlusion were made, and three in the other two, varying the application method and product. In two cases the fistulas initially reopened and in the other an occlusion was demonstrated by esophagogram and remission of respiratory symptoms during eight months was achieved. In a posterior control, a thread-like fistula reappeared but did not affect clinical improvement. The possibility to employ endoscopic techniques always seemed very promising for this type of pathology. The appearance on the market of various substances with capacity of occlusion has allowed us to employ them in comparative studies and simultaneously test the efficacy of the laryngeal mask in this kind of situations. The results show the complete ineffectiveness of some of these products and the relative possibilities of others, although in our experience we have yet to achieve any definitive occlusion.
