Angiodysplasia of the caecum, pill camera image. Angiodysplasia is a condition in which blood vessels in the wall of the intestines become deformed, forming lesions that bleed into the intestine. An angiodysplasia lesion is seen at centre right (red). The caecum is the pouch where the small intestine meets the large intestine. Blood loss can lead to anaemia, which may require transfusions. If the lesions are localised in one area, removal of that part of the intestines may treat the condition, but in many cases the lesions are widespread and that is not viable. Hormone therapy with oestrogens can stop bleeding by inducing clotting, but that has many side effects. A pill camera is a drug pill-sized camera that relays pictures of the digestive tract.
