Abstract
Acute esophageal necrosis is a rare entity endoscopically described as a black appearance of esophageal mucosa, generally of circumferential distribution that extends proximally from the gastroesophageal junction, and affects a variable length of this organ. It has a multifactorial etiology that includes a combination of ischemic mucosal esophageal vascular compromise associated with gastroesophageal reflux in patients with multiple comorbidities. Clinical management focuses on general support measures and treatment of the underlying illness and comorbidities. Although this pathology usually tends to a restitution-ad-integrum in 7-10 days, these patients have a high mortality rate more related to their clinical conditions and not due to this entity itself. Therefore, early diagnosis is crucial to initiate proper treatment. We present two cases of AEN in patients who underwent orthotopic liver transplantation.
