Abstract
A 55-year-old man with a history of having undergone gastroduodenostomy (Billroth I method) for perforated duodenal ulcer was admitted to our hospital due to hematemesis that occurred 4 days after eating uncooked mackerel. Emergency gastroduodenoscopy revealed an A1 stage hemorrhagic ulcer with bleeding at the greater curvature of the mid-gastric body in the remnant stomach. An Anisakis simplex was found at the base of the ulcer, which was successfully removed by biopsy forceps. An endoscopic hemostasis procedure was performed on the visible vessels at the base of the ulcer to stop the bleeding. Thereafter, the patient was treated with proton pump inhibitors (PPI), and the ulcer had improved to H2 stage at 14 days after the hospital admission. We report a rare case of hemorrhagic gastric ulcer associated with anisakiasis.
