Octreotide in gastrointentinal angiodysplasia – pro

image11

Angiodysplasias are usually asymptomatic but they can cause of GI bleeding in 3–6% of all patients and are a more common cause of beeeding in the elderly. It is notoriously difficult to treat. A number of reports suggest that it is a valuable adjunct in the treatment of gastro-inestinal dysplasia and can decrease bleeding. There are no supportive guidelines to my knowledge but the role of somatostatin analogues for refractory bleeding GI angiodysplasias has been systematically reviewed by Brown et al.
He concluded: “A significant number of patients with bleeding gastrointestinal angiodysplasia respond to treatment with octreotide by reducing the need for blood products. As all the included studies had small sample sizes, multicenter randomized trials are needed to confirm these findings. However, it seems reasonable to administer octreotide especially in patients with refractory bleeding, inaccessible lesions and in patients at high risk for other interventions.”.
