The lesion of Dieulafoy is a vascular malformation characterized by the presence of a large arterial vessel in the submucosa and occasionally in the mucosa, which can erode and cause severe, recurrent and sometimes fatal hemorrhage. It is a rare cause of gastrointestinal bleeding and responds to less than 2% of episodes of acute gastrointestinal bleeding. The duodenal Dieulafoy lesion has been reported in a small number of cases and the intradiverticular is exceptional. Endoscopy is the diagnostic method of choice and in the last decade endoscopic therapy is the preferred technique due to its high effectiveness and low incidence of complications. We present the case of an 82-year-old patient with severe upper gastrointestinal bleeding due to an intradiverticular duodenal injury diagnosed in emergency endoscopy and treated effectively by rubber band ligation.
