[Usefulness of endoscopic hemostasis in Dieulafoy's vascular disease]

We report three cases of "Dieulafoy's gastric erosion" or "Exulceratio simplex", which is rarely recognized but is not an uncommon cause of upper gastrointestinal hemorrhage, usually very dangerous, as it's an arterial bleeding. In all cases an emergency endoscopy was performed, and treatment with combination of local sclerosis and vessel's electrocoagulation was successful. We insist in the potential benefits of endoscopic treatment in all these occasions, if it's possible, since even exact diagnosis of the bleeding site is very difficult in some patients.
