Clinical presentations, management, and outcomes of acute esophageal necrosis: a systemic review

BACKGROUND

To review all the reported literature on acute esophageal necrosis.

RESEARCH METHODS

Databases were searched using the special Medical Subject Heading (MeSH) terms. All the available reported cases of acute esophageal necrosis were analyzed.

RESULTS

A total of 154 cases were identified and 130 cases were analyzed. The mean age of presentation was 61 years, and 70% of cases were males. The most common presenting symptoms were hematemesis in 66%, shock in 36%, melena in 33%, abdominal or substernal pain in 28%. The most common comorbidities reported were diabetes in 38%, hypertension in 37%, alcohol abuse in 25%, and chronic kidney disease in 16%. On upper endoscopy, 51% had a distal disease, 36% had pan esophageal, and only 2% had a proximal disease. 84% of patients were treated with IV Proton Pump Inhibitors, 22% received transfusions, 23% got antibiotics for underlying sepsis, 14% also received sucralfate, and 4% required surgery for treatment. The mortality rate was 32%, while perforation was reported in 5% and stricture formation reported in 9% of patients.

CONCLUSIONS

Patients with acute esophageal necrosis can have a favorable outcome if treated appropriately.

Comprehensive review of acute oesophageal necrosis

Acute oesophageal necrosis, also known as 'black oesophagus', is a rare condition characterised by the black discolouration of the oesophageal mucosa on endoscopy and involves the distal oesophagus in majority of cases but may also extend proximally. A number of conditions are found to be associated with it and it is thought to occur due to a combination of hypovolaemia and inadequate oesophageal protective mucosal barrier function. Gastric secretions may have a direct effect on the oesophageal mucosa. We present a case of a woman who presented with haematemesis and significant hypotension after a session of haemodialysis. Black oesophagus was confirmed on esophagogastroduodenoscopy. She was given two units of packed red blood cells and one unit of platelets, and started on a pantoprazole infusion. However, despite rigorous attempts at resuscitation the patient failed to recover.
