[Endoscopic sclerosis of bleeding caused by Dieulafoy's lesion].

The upper gastrointestinal bleeding by Dieulafoy's lesion is a rare cause of bleeding, it is a massive haemorrhage and it is difficult to diagnose. Endoscopy is the diagnostic method of choice, in many cases are necessary repeated examinations. Endoscopic therapy is the therapeutic approach of choice, it can achieve the hemostasis in more than 90% of cases; combined therapy methods being more effective than single monotherapy. Surgical treatment remains for cases of uncontrolled hemorrhaging. Dieulafoy's lesion is a rare condition. We have only two nation wide reports. We present two cases of patients with gastric Dieulafoy's lesion with active bleeding which were successfully treated with injection endoscopic of epinephrine and absolute alcohol therapy, showing no relapse of bleeding after 12 months. They did not present other episode of haemorrhage during the twelve months after initial bleeding.
