Overview
Medical Therapy
If the anemia is severe, blood transfusion is required before any other intervention is considered. Endoscopic treatment is an initial possibility, where cautery or argon plasma coagulation (APC) laser treatment is applied through the endoscope. Cauterization may be helpful in stopping the bleeding at endoscopically accessible sites. [1] Mechanical hemostasis using hemoclips or endoclips may be used for localized lesions. Injection sclerotherapy using sclerosants like sodium tetradecyl sulfate or ethanolamine is another option, but rarely used. If the bleeding is from multiple or inaccessible sites, systemic therapy with medication may be necessary. [2] [3] First-line options include the antifibrinolytics tranexamic acid or aminocaproic acid. Estrogens can be used to stop bleeding from angiodysplasia. Estrogens cause mild hypercoaguability of the blood. Estrogen side effects can be dangerous and unpleasant in both sexes. Changes in voice and breast swelling is bothersome in men, but older women often report improvement of libido and perimenopausal symptoms. (The worries about hormone replacement therapy/HRT, however, apply here as well.)
In difficult cases, there have been positive reports about octreotide[4] and thalidomide,[5]
