Endoscopic treatment of Dieulafoy hemorrhage.

Bleeding from a Dieulafoy lesion is an underdiagnosed source of upper gastrointestinal bleeding. The literature is almost universally in support of surgical therapy as its treatment. We report three patients with bleeding Dieulafoy lesions who were treated successfully with endoscopic therapy--two by bipolar electrocoagulation and one by endoscopic sclerotherapy.
