A CASE OF BLACK ESOPHAGUS DUE TO ACUTE NECROTIZING ESOPHAGITIS

Abstract

A 45-year-old man was admitted to our hospital with consciousness disorder. He was diagnosed as disturbances of circulation caused by diabetic acidosis. Because he vomited blood 4 days before hospitalization, upper gastrointestinal endoscopy was performed after hospitalization. It revealed a black esophagus and biopsy specimens disclosed necrotizing tissue and granulation tissue, and the patient was diagnosed as having acute necrotizing esophagitis. Upper X-ray examination showed esophageal hernia, decreased LES pressure and hypomotility of esophageal contraction were indicated by esophageal manometry. It was suspected that ref lux of gastric juice from stomach to esophagus was a cause of this case.
