Multidisciplinary Management of Acute Esophageal Necrosis Secondary to Alcoholic Lactic Acidosis: A Case Report

Background and Clinical Significance: Acute esophageal necrosis (AEN), or black esophagus, is an extraordinary rare source of acute upper gastrointestinal bleeding. Its pathogenesis is still poorly understood, whereas etiology seems to be multifactorial, mainly involving esophageal ischemia, increased acid reflux, and reduced mucosal defenses. Although alcohol abuse has been reported to be a common trigger factor, only one case of AEN due to severe alcoholic lactic acidosis has been described up to date. Case Presentation: Herein, we describe a case of a non-cirrhotic 61-year-old lady with a history of chronic alcohol abuse, who was admitted to the Emergency Room due to upper gastrointestinal (GI) bleeding. AEN caused by severe alcoholic lactic acidosis was promptly diagnosed by subsequent investigations, including blood test, urinalysis, computed tomography, and upper GI endoscopy. The treatment involved a multidisciplinary, aggressive medical approach, which included one hemodialysis session. Conclusions: This is the second documented case of AEN secondary to alcoholic lactic acidosis, successfully treated with a previously unreported aggressive multidisciplinary approach, involving one hemodialysis session. It highlights the value of a multidisciplinary approach in managing such complex and rare conditions.
