| English abstract | For many years, the hematologic changes occurring in hepatosplenic Manson's schistosomiasis have been defined as hypersplenism. Initially, the belief was that removal of the spleen would normalize the hematologic values. However, hematimetric normalization was observed in surgeries for the treatment of portal hypertension in which the spleen was preserved. In view of these findings, it is necessary to verify the clinical and laboratory profile of these patients in order to define the real presence of hypersplenism. This study was conducted on 51 patients with Manson's schistosomatic portal hypertension divided into five groups: Group 1, non-operated patients under clinical control; Group 2, patients submitted to distal splenorenal shunt; Group 3, patients with subtotal splenectomy and central splenorenal shunt; Group 4, patients with total splenectomy and central splenorenal shunt; Group 5, patients with total splenectomy and portal-variceal disconnection. Clinical signs of hypersplenism were assessed in all patients. Hematologic values of the pre- and postoperative periods were compared. Immunoglobulin counts of the patients were verified in the late postoperative period. The five groups were compared by Kruskal-Wallis test. The pre- and postoperative values were compared using Friedman and paired t tests, with significance for p< 0.05. In all operated groups, hematimetric values, leukocyte counts, platelet number and prothrombin time were higher during the postoperative period. With respect to the immunoglobulins, the postoperative values of IgM, IgG and IgA were normal. Patients with schistosomatic portal hypertension and peripheral cytopenia cannot be classified as having hypersplenism, but rather as having pancytopenia due to splenomegaly caused by difficulty of portal blood drainage |

Inicialmente, acreditava-se que apenas a remoção do baço normalizava os valores hematológicos, entretanto, em cirurgias para o tratamento da hipertensão porta nas quais o baço era preservado, observou-se normalização dos valores hematimétricos. Cabe correlacionar o quadro clínico e laboratorial para definir a real existência de hiperesplenismo. MÉTODO: Foram estudados 51 doentes portadores de hipertensão porta por esquistossomose mansônica distribuídos em cinco grupos: Grupo 1- pacientes não operados e em controle clínico, Grupo 2- pacientes submetidos a anastomose esplenorrenal distal, Grupo 3 - pacientes com esplenectomia subtotal e anastomose esplenorrenal proximal, Grupo 4 - pacientes com esplenectomia total e anastomose esplenorrenal proximal e Grupo 5 - pacientes com esplenectomia total e desconexão porta-varizes. Sinais clínicos de hiperesplenismo foram pesquisados em todos os doentes. Os valores hematológicos e as contagens das imunoglobulinas do pré e do pós-operatório foram comparados pelos testes de Friedman e t para amostras emparelhadas. Os grupos foram comparados pelo teste de Kruskal-Wallis, com significância p< 0,05. RESULTADOS: As médias dos valores hematimétricos dos doentes mostraram leucopenia, plaquetopenia e elevação do tempo de protrombina no período pré-operatório. Esses pacientes apresentavam eventuais episódios de sangramento pelas varizes esofágicas e.. |
