[Duodenal angiodysplasia: an unusual cause of intestinal obstruction]

Angiodysplasia is a relatively rare lesion that however may be a major source of upper and lower gastrointestinal bleeding. It's mostly related to the aging and degeneration of the blood vessels, as it occurs in older adults. Clinical presentation is variable, ranging from asymptomatic cases over iron deficiency anaemia to acute or recurrent bleeding. We present a case of 60 year-old woman presented with anaemia and intestinal obstruction. Diagnosis can usually be made using endoscopy, sometimes with additional biopsy. Treatment can be symptomatic, including iron supplements and transfusion therapy or causal, including therapeutic endoscopy (laser, electrocautery, heater probe or injection sclerotherapy), therapeutic angiography and surgery.
