Acute Esophageal Necrosis Associated With Acute Pancreatitis.

Acute esophageal necrosis or "black esophagus" is a rare clinical entity characterized by necrosis of the esophageal mucosa resulting from low-flow hemodynamic states. The disease commonly presents with upper gastrointestinal hemorrhage, and the diagnosis is based on the presence of circumferential black appearance of the distal esophagus with variable proximal involvement and sparing of mucosa distal to the esophagogastric junction. The disease is associated with a high mortality rate, and treatment is supportive. We describe a case of acute esophageal necrosis associated with acute postendoscopic retrograde cholangiopancreatography pancreatitis.
