Gastrointestinal Bleeding From a Transverse Colon Dieulafoy Lesion

Dieulafoy lesions are an extremely rare disease that can cause gastrointestinal bleeding and colon bleeding. Lower gastrointestinal bleeding caused by a transverse colonic Dieulafoy lesion is extremely rare. This study describes the case of a 68-year-old woman who took oral rivaroxaban for atrial fibrillation and presented with massive lower gastrointestinal bleeding associated with a rare transverse colonic Dieulafoy lesion. Hemostasis was successfully achieved by thermal coagulation and the application of endoscopic hemoclips. Lastly, we reviewed previous literature on the diagnosis and treatment of colonic Dieulafoy disease.
