  • Title: Splenectomy for agnogenic myeloid metaplasia.
    Author: Coon WW, Liepman MK.
    Journal: Surg Gynecol Obstet; 1982 Apr; 154(4):561-3. PubMed ID: 7064091.
    Abstract:
    Only a fraction of the patients with myeloid metaplasia have indications for splenectomy develop. Palliation for symptomatic splenomegaly is highly successful. Significant relief from hypersplenism, anemia or thrombocytopenia was achieved, however, in less than half of the patients. Since patients with severe thrombocytopenia are at continuing risk of spontaneous hemorrhage and of bleeding after minor trauma, splenectomy appears to be justified in these patients, provided that studies of peripheral blood and bone marrow have excluded those with leukemic conversion. The benefit obtained from splenectomy in patients with chronic anemia requiring frequent transfusions in less certain, particularly in men and in patients converting to myeloid metaplasia from polycythemia vera. In some instances, the continuation of transfusions may result in less morbidity and better palliation than operation. Although the course of this myeloproliferative disorder from first symptoms to death frequently extends for more than a decade, the manifestations which may provide an indication for splenectomy usually occur late in the course of the disease. The element as well as the morbidity of the operation makes a thorough evaluation of each patients essential before splenectomy is considered.
