Severe digestive hemorrhage by duodenal injury of Dieulafoy lesion

: The Dieulafoy lesion is a vascular anomaly generally located in proximal stomach. and consist of the presence of an artery of heavy caliber in the submucosa and mucosa, although the definitive diagnosis is anatomopathologic, with the endoscopic examination we can obtained a high precision approach. Is a rare cause of gastrointestinal bleeding although potentially fatal etiology of gastrointestinal hemorrhage. It occurs in fewer than 2% of the episodes of acute digestive hemorrhage. The injury of duodenal Dieulafoy has been communicated in a reduced number of cases and in some of them it has needed surgical treatment. We effectively presented and treat this case of a young man diagnosed in the initial endoscopy and was treated by means of injection of adrenalin and absolute alcohol.
