Acute esophageal necrosis complicating diabetic ketoacidosis in a patient with type II diabetes mellitus and excessive cola consumption: a case report.

Unlabelled: Acute esophageal necrosis (AEN) implicates poor tissue perfusion, functionally defective mucosal barrier, and corrosive injury of the esophageal mucosa, typically characterized by diffuse, circumferential greyish or black discoloration of the esophagus in esophagogastroduodenoscopy. Low-volume states, as diabetic ketoacidosis (DKA), predispose to AEN. Cola drinks diminish the esophageal pH by decreasing the lower esophageal sphincter pressure.
