Medical and hormonal therapy in occult gastrointestinal bleeding.
In this age of modern technology and aggressive but noninvasive therapies, the idea of treating an identifiable but discrete bleeding lesion with systemic medical therapy seems an anachronism. But medical therapy can be the treatment of choice for some bleeding vascular lesions of the gut. Though most vascular lesions appear similar endoscopically and are a cause of gastrointestinal bleeding, they consist of various pathologic identities. These different lesions have not only different pathologic appearances, but also different prognoses. The natural history of many of these lesions remains largely unknown. Long-term success in controlling bleeding must be measured in the context of the responsible lesion's frequency of occurrence and recurrence. Medical therapy can include hopeful watchful waiting, routine blood transfusions, or specific medications. Medical therapy has been pursued along two lines. The most common form of medical therapy has been simple supportive care. This may include iron therapy and avoidance of aspirin and other anticoagulants. Transfusions may be necessary, occasionally or on a regular basis. The second form of medical therapy has been the use of estrogens. There have been other medical attempts to control bleeding from intestinal vascular lesions. Somatostatin has been used in an uncontrolled fashion, as has aminocaproic acid. Vascular lesions of the bowel are not all the same. Medical therapy of vascular lesions is contrary to general present practice. Endoscopic or surgical therapy is presently considered best because of its ease, relatively good long-term results, and the lack of a clearly effective, well-tolerated medical therapy. Medical therapy is usually reserved for diffuse vascular diseases of the bowel, for vascular lesions located in relatively inaccessible locations, for patients with continued bleeding despite endoscopic or surgical management, and for patients who are not candidates for either endoscopic or surgical therapy.
