Background and aims: The incidence of erosive esophagitis in emergent endoscopy for upper gastrointestinal bleeding is not rare but the clinical and endoscopic findings have not been fully investigated. The aim of the present study was to clarify features of acute esophagitis cases showing acute onset and severe endoscopic findings. Methods: We defined severe esophagitis that endoscopically showed circumferential diffuse mucosal lesion involving at least the entire lower third of the esophagus as acute esophageal mucosal lesion and investigated the clinical and endoscopic characteristics. Results: We experienced six cases of black or dark esophagitis and six non-black esophagitis. Both groups showed common clinical features. Patients were predominantly males older than middle age. The presenting symptoms were upper gastrointestinal bleeding such as coffee-ground-like vomit, hematoemesis or tarry stool. Seven cases had a history of taking nonsteroidal anti-inflammatory drugs. Endoscopically, both types of cases showed diffuse circumferential erosion in the lower esophagus, which continuously extended, and worsened towards the esophagogastric junction. All had esophageal sliding hernia and five cases had duodenal mucosal lesion. All cases rapidly improved with a proton pump inhibitor except one case. Conclusion: Black and non-black esophagitis were considered to belong to the same disease entity, acute esophageal mucosal lesion, which should be recognized as a differential diagnosis on emergency endoscopy for upper gastrointestinal bleeding.
