. Pigmentation is usually black friable mucosa. The disorder is extremely rare, as only 88 patients over a span of 40 years have received this diagnosis. Specific study of the disorder's mortality rate is mentioned at 31.8%, but new research suggests mortality rates vary from 30-50%. The exact triggering mechanism for this disorder is still unknown, but is likely a multifactorial.

Signs and symptoms

AEN has never been recorded as a one symptom disorder, but instead present by multiple symptoms. The symptoms vary from the severity of the disorder. The most classic sign of AEN is the dark pigmentation of esophageal mucosa in an upper endoscopy, usually viewed as an ulcer or as an infectious disease. Necrosis can be found mostly between the three distals of the esophagus, but stops abruptly at the gastroesophageal junction. The basic and most common symptoms reported are blood in stool

Diagnosis

Acute esophageal necrosis can only be diagnosed by an upper gastrointestinal endoscopy.

Treatment

Currently, there is no direct treatment for AEN. Only treatment is for the underlying main diseases or conditions. Appropriate hydration is set. Antacids are also added for further recovery support. Common support drugs of antacids are either H2 receptor antagonists

History

Acute esophageal necrosis was first described by Goldenberg et al. in 1990. Cases have emerged since 1960, but have never been described as the common names for AEN. Due to its rarity, only 88 cases have been pronounced AEN, but most likely there is much more. Gurvits et al. describes AEN as "poorly described in medical literature".
