espanolLa lesion de Dieulafoy (LD) es una causa rara de hemorragia digestiva generalmente grave, secundaria a la presencia de un vaso de calibre persistente en la capa submucosa, de dificil diagnostico por el pequeno tamano de la erosion y la apariencia de la mucosa no patologica que lo recubre. Su localizacion en colon es infrecuente. Presentamos el caso de un paciente con hemorragia digestiva baja severa secundaria a dicha lesion en colon ascendente, diagnosticada mediante colonoscopia y tratada con adrenalina y argon plasma, con buenos resultados Palabras clave: Hemorragia digestiva, lesion de Dieulafoy, lesion vascular, tratamiento endoscopico EnglishDieulafoy's lesion (DL) is a rare cause of usually severe gastrointestinal bleeding, secondary to the presence characterized by a large tortuous arteriole in the stomach wall (sub mucosal) that erodes and bleeds. It is difficult to diagnose because of the small size of the erosion and the non-pathological appearance of the mucosa covering it. It is rarely located in the colon. We report the case of a patient with severe lower gastrointestinal bleeding secondary to Dieulafoy's lesion in the ascending colon, diagnosed by colonoscopy and treated with adrenaline and argon plasma obtaining good results.
