Abstract
A tracheo-esophageal fistula occurred spontaneously in a 50-year-old man. At endoscopy it was found to be due to a perforated ulcer localized in heterotopic gastric mucosa in the cervical esophagus. Histological examination revealed ulcer necrosis and granulation tissue, as well as glands of the stomach type with chief and other cells. Malignant or specific genesis was excluded. Based on the histological finding, the attempt was successfully made of closing the fistula within fibrin glue in two sittings. All symptoms ceased immediately after the second sitting. Later radiological and endoscopic examinations no longer demonstrated either the fistula opening nor a fistulous tract.
