Acute Esophageal Necrosis Secondary to a Paraesophageal Hernia

Acute esophageal necrosis (AEN) or “black esophagus” is a rare clinical entity caused by necrosis of distal esophageal mucosa stemming from esophageal ischemia. Possible etiologies are broad but most commonly include possible triggers of low-flow vascular states in the esophagus, including infections, broad-spectrum antibiotic us e, and gastric volvulus, among others. Patients most commonly present clinically with acute onset hematemesis and melena. Here, we describe a patient who initially presented with multiple nonspecific gastrointestinal symptoms, including abdominal pain and nausea, that progressed over a 10-day period , culminating in multiple episodes of hematemesis prior to presentation. Endoscopic evaluation confirmed the diagnosis of AEN and unveiled a possible paraesophageal hernia (PEH) as the causative factor. A subsequent videofluoroscopic barium swallow was utilized to better characterize the upper gastr ointestinal anatomy and confirmed the PEH as a likely etiology. Esophagogastroduodenoscopy (EGD) can often identify PEH independently, but in patients with AEN secondary to a possible, but unclear, PEH on EGD, a videofluoroscopic barium swallow is an appropriate and useful next step in confirming th e diagnosis. While treatment of AEN traditionally involves fluid resuscitation, intravenous protein pump inhibitors, and total parenteral nutrition, surgical intervention is often indicated in patients who have a contributing and symptomatic PEH.Case Rep Gastro...
