Abstract
A 66-year-old male was admitted to hospital because of epigastric pain due to cholelithiasis, with no complaint of coughing. On esophagography, an esophagobronchial fistula with diverticulum was incidentally discovered in the middle of the thoracic esophagus. Esophagoscopy revealed the presence of a fistula, mucosal bridges and postinflammatory changes in the f undus of the diverticulum. Bronchoscopy showed a f istulous opening with fold convergence in the right main bronchus. CT scanning demonstrated calcified mediastinal lymphnodes around the diverticulum. On January 29, 1992, excision of the fistula and diverticulum was performed. During the operation, inflammatory changes and lymph nodes adherent to the diverticulum were seen. The patient's postoperative course was uneventful. It appeared that this fistula was produced by formation and perforation of the diverticulum resulting from mediastinal lymphadenitis.
