“Black Esophagus” and Gastric Volvulus Following Slipped Laparoscopic Adjustable Gastric Band

To review the entity “black esophagus” and sequela of a slipped laparoscopic adjustable band. The patient’s history, physical examination, imaging, and endoscopic findings were reviewed. Detailed review of pathophysiology, presentation, diagnosis, management, and natural history was conducted. “Black esophagus,” also known as acute esophageal necrosis (AEN), is a rare condition resulting in black discoloration of the mid to distal esophagus with less than a hundred reported cases. It has not been previously documented in bariatric surgery or following laparoscopic adjustable gastric banding. The volvulus was reduced at surgery, and the esophageal changes resolved without sequela. “Black esophagus” is an acute, ominous-appearing condition with a spectrum ranging from superficial mucosal disease to transmural involvement with perforation. Fortunately, esophageal resection is rarely required.
