[Congenital broncho-esophageal fistula in an elderly patient with lung abscess].

A 60-year-old man who had been treated for pneumonia by another hospital was suspected to have a broncho-esophageal fistula, and was referred to our hospital for surgical treatment. Chest computed tomography( CT) demonstrated a lung abscess. Upper gastrointestinal endoscopic examination demonstrated an esophageal diverticulum. He underwent the resection of the fistula and left lower lobectomy of lung under left thoracotomy. Operative findings showed no severe adhesion around fistula, suggesting its congenital origin, which was also pathologically supported later. He suffered from postoperative empyema by anaerobe infection, which was successfully controlled by open drainage.
