Severe Bleeding Gastric Barotrauma Unmasking Collagenous Gastritis

Abstract

An 83-year-old man with a history of celiac disease, collagenous colitis, and collagenous sprue presented with nausea, vomiting, diarrhea, and weight loss over 3 months, prompting an esophagogastroduodenoscopy. Initial forward view inspection was unremarkable. On retroflexion, diffuse oozing blood was suddenly seen in the fundus (Figure A). Bleeding was treated with hemostatic powder spray. Barotrauma was suspected, despite usual insufflation. Repeat endoscopy 3 days later revealed serpiginous ulceration in the gastric body and fundus (Figure B).
