[Very elderly case of spontaneous esophageal rupture successfully treated by conservative treatment;report of a case].

A 94-year-old female patient presenting with vomiting and hematemesis, was transferred to our hospital. On a chest computed tomography (CT) image, mediastinal emphysema was seen with a little amount of bilateral pleural effusion, therefore, a diagnosis of spontaneous esophageal rupture was made. It took 6 hours to make a definite diagnosis of this disease, and conservative therapies were done including administration of antibiotics and proton-pump inhibitor. The patient was able to drink water on 4th hospital day, and was discharged on 19th hospital day. At about 2 months after the onset, a gastrointestinal fiberscope showed just only scar at the lower thoracic esophagus.
