[Acute lower massive digestive hemorrhage due to a jejunal angiomatoid hamartoma. Case report]

Acute hemorrhage of the lower digestive tract is massive in 20% of the cases, requiring emergency surgery. In such cases, a preoperative diagnosis of the point of bleeding is essential. In order to determine this, any combination of oral panendoscopy, rectal sigmoidoscopy, colonoscopy, arteriography and isotopic studies should be used. The most frequent causes are right colonic angiodysplasia and colonic diverticulosis. The authors present a case of lower digestive bleeding due to an angiomatoid hamartoma located in the first jejunal segments, a rare pathology as a cause of hemorrhage. The diagnosis was obtained by selective arteriography. Oral panendoscopy and colonoscopy were also performed.
