A Case of Dieulafoy's Lesion Presenting Upper Gastrointestinal Bleeding in a Child in the Acute Phase of Kawasaki Disease / 소아과

ABSTRACT

Dieulafoy's lesion is an unusual cause of massive gastrointestinal bleeding resulting from the erosion of an abnormally large submucosal artery. Recently, improvement of endoscopic techniques has made effective hemostasis possible in most cases of Dieulafoy's lesion. Aspirin, which is an anti-inflammatory agent, increases the incidence of major upper gastrointestinal complications. Gastroduodenal mucosal injury associated with aspirin therapy in patients in the acute phase of Kawasaki disease is a rare complication that may require urgent medical intervention. We experienced a rare case of active bleeding from Dieulafoy's lesion in the stomach who was treated with oral aspirin in the acute phase of Kawasaki disease. If there is massive hematemesis during the treatment of Kawasaki disease, Dieulafoy's lesion should be considered even though it is rare.
