  • Title: [Splenectomy in idiopathic thrombopenic purpura and in myelofibrosis. A retrospective study of platelet increase, hemorrhagic complications and mortality].

    Abstract:
    In a retrospective study of 39 splenectomies, patients with increased blood cell breakdown (13 cases of idiopathic thrombocytopenic purpura (ITP), 5 cases of hereditary spherocytosis, 2 of Felty's syndrome and 2 of autoimmune hemolytic anemia) were compared with those patients also presenting decreased blood cell production [14 cases of myelofibrosis (MF) with splenomegaly and 3 cases of advanced chronic myelogeneous leukemia (CML)]. Platelet regeneration post-operatively was significantly (p less than 0.01) more rapid in the ITP than in the MF group. Only 1/22 patients in the ITP group had major post-operative complications as compared to 10/17 in the MF group. None of the patients in the ITP group died within 25 days of operation as compared to 5/17 in the MF group. Only 3/22 patients in the ITP group lost more than 800 ml of blood during the operation as compared to 8/17 with MF. No statistically significant higher blood loss was found in patients with less than 30 x 10(9) platelets/l preoperatively, compared to those with higher platelet counts. However, correlation between the splenic weights and amount of blood loss was statistically significant (p less than 0.01). Thus, splenectomy seems much better tolerated in patients with ITP, even if platelets are low, than in patients with myelofibrosis.
