title: Acute necrotizing esophagitis: role of nonsteroidal anti-inflammatory drugs.
abstract: BACKGROUND
  Acute necrotizing esophagitis (ANE) is a rarely described entity that is thought to be a cause of upper gastrointestinal (UGI) bleeding, The present study examined the incidence of ANE among patients with UGI bleeding, as well as the clinical features of ANE, and the coexisting illnesses and medication histories of ANE patients.
  
  
  METHODS
  A retrospective analysis of clinical and endoscopic findings and the clinical course in 16 patients with ANE was carried out over a 3-year period.
  
  
  RESULTS
  We observed 16 patients (6%) of ANE in 239 patients with UGI bleeding during the 3-year period. The average age of the patients was 62.5 years. The lesions predominantly affected the lower third of the esophagus, and hiatal hernia was the most common (63%) coexisting endoscopic finding. All patients had coexisting disease. Fifty percent of patients with ANE (eight patients) had taken nonsteroidal anti-inflammatory drugs (NSAIDs). ANE also occurred in four patients with diabetic ketoacidosis. Supportive therapy, including parenteral nutrition and administration of a proton pump inhibitor, was effective.
  
  
  CONCLUSIONS
  ANE is more common than has been previously reported, and it should be included in the differential diagnosis of UGI bleeding. ANE could be characterized as an "acute esophageal mucosal lesion," particularly in aged patients with hiatal hernia and among those who consume NSAIDs.
