¿Presenta características diferenciales la hemorragia digestiva alta por lesión de Dieulafoy?

Active bleeding and gastric location of the lesion were more frequent in the DL group than in the ulcer group. Diagnosis of DL is difficult, requiring a greater number of gastroscopies. Initial hemorrhage severity and the success rate of endoscopic treatment were similar in the two groups. The higher mortality found in DL can be explained by the greater comorbidity in these patients, with a worse bleeding tolerance.
