[Esophago-bronchial fistulas in adult].

Esophago-bronchial fistulas in adult are rare and for the most part are due to a malignant tumor. The authors present two cases of benign Esophago-bronchial fistula which were discovered accidentally by esophagography. One case was considered to be congenital. Esophagography is the most useful for diagnosis of this disease.
