RESUMO

Introducción: Desde 1986 se ha introducido en nuestro país la esplenectomía parcial, que logra prevenir la recurrencia de la crisis de secuestro esplénico y disminuir la incidencia de sepsis sobreaguda postesplenectomía. Objetivo: Comparar desde el punto de vista clínico y de laboratorio los pacientes con esplenectomía total y parcial. Pacientes y métodos: Se estudiaron todos los pacientes con drepanocitosis, seguidos en el Instituto de Hematología e Inmunología, que se hubieran sometido a esplenectomía durante la edad pediátrica. Resultados: Se incluyeron 39 pacientes en cada método de esplenectomía; la mayoría eran varones (60,3%) y predominaba la anemia drepanocítica (69,2%). La edad de aparición de la esplenectomía fue menor en la de tipo parcial (4,7 años; p= 0,009) que en la total (6,7 años), y el tiempo de seguimiento fue de 12,5 años. El grupo de esplenectomía total presentó un mayor aumento de hemoglobina, leucocitos y plaquetas (p= 0,039), así como valores elevados de lactato deshidrogenasa (p= 0,015), hemoglobina plasmática (p= 0,001) y velocidad de regurgitación tricuspídea (p= 0,038). La crisis vasooclusiva dolorosa fue más frecuente tras la esplenectomía total (75,8 ± 14,3 frente a 39,8 ± 10,1; p < 0,001), al igual que las úlceras maleolares (p= 0,04). La crisis hepática y la mortalidad fueron también más frecuentes en la esplenectomía total aunque sin significación estadística (p= 007 y p= 0,305, respectivamente). Conclusiones: La esplenectomía parcial presenta menos complicaciones a largo plazo que la total (AU)


Introduction: Since 1986 has been introduced in our country partial splenectomy, which prevent the recurrence of splenic sequestration crisis and possible reduce the number of overhelming septicemia. Objective: Compare clinical and laboratory aspects in patients with total and partial splenectomy. Patients and methods: All patients with sickle cell disease were studied, followed at the Instituto de Hematología e Inmunología, who have had a splenectomy in childhood. Results: 39 patients were included in each method of splenectomy, where a predominance of males (60.3%) and sickle cell anemia (69.2%). Splenectomy age was lower in the partial, 4.7 years than in total splenectomy, 6.7 years (0.009). Follow-up time was 12.5 years. Total splenectomy group had greater increase in hemoglobin, leucocytes and platelets (p= 0.039), elevated LDH levels (p= 0.015), plasma hemoglobin (p= 0.001) and tricuspid regurgitation velocity (p= 0.038). Vaso-occlusive painful crises was more frequent after total splenectomy (75.8 ± 14.3 vs. 39.8 ± 10.1; p <0.001), as leg ulcer (p= 0.04). Hepatic crisis (p <0.07) and mortality were higher in individuals with complete splenectomy (p= 0.305) but withouth significative statistics. Conclusions: Partial splenectomy has fewer long-term complications that total (AU)

RESUMO

INTRODUCCIÓN: La esplenectomía total en la drepanocitosis se relaciona con riesgo de infecciones sobreagudas y con aumento de la incidencia de otros eventos, lo que no se ha comunicado en pacientes con esplenectomía parcial. En este estudio se caracterizó a los pacientes con drepanocitosis y esplenectomía parcial, y se comparó el comportamiento clínico y de laboratorio con los pacientes no esplenectomizados. MATERIAL Y MÉTODOS: Se estudió a 54 pacientes con drepanocitosis sometidos a esplenectomía parcial durante la edad pediátrica, desde 1986 hasta el año 2011, en el Instituto de Hematología e Inmunología. Se compararon con 54 pacientes no esplenectomizados seleccionados por muestreo aleatorio con características similares. RESULTADOS: La esplenectomía parcial se realizó a una edad media de 4,1 años, con una frecuencia mayor en la anemia drepanocítica (70,4%) y su causa más común fue la crisis de secuestro esplénico recurrente. Las complicaciones posoperatorias más frecuentes fueron: fiebre de origen desconocido (14,8%) y síndrome torácico agudo (11,1%). Después de la esplenectomía, aumentaron significativamente los leucocitos, neutrófilos y plaquetas; estos 2 últimos parámetros se mantuvieron elevados de manera significativa cuando se compararon con los pacientes no esplenectomizados. No hubo diferencias en la incidencia de los eventos clínicos, excepto el secuestro hepático, que fue más frecuente en los esplenectomizados. CONCLUSIÓN: La esplenectomía parcial constituyó un proceder seguro en los pacientes con drepanocitosis. No hubo diferencias en el cuadro clínico entre los niños esplenectomizados y los no esplenectomizados, salvo la mayor frecuencia de crisis de secuestro hepático en los primeros


INTRODUCTION: Total splenectomy in sickle cell disease is related to a high risk of fulminant sepsis and increased incidence of other events, which have not been reported in patients with partial splenectomy. In this study we examined the patients with sickle cell disease and partial splenectomy and compared the clinical and laboratory results with non-splenectomized patients. MATERIAL AND METHODS: We studied 54 patients with sickle cell disease who underwent partial splenectomy in childhood from 1986 until 2011 at the Institute of Hematology and Immunology. They were compared with 54 non-splenectomized patients selected by random sampling with similar characteristics. RESULTS: Partial splenectomy was performed at a mean age of 4.1 years, with a higher frequency in homozygous hemoglobin S (70.4%), and the most common cause was recurrent splenic sequestration crisis. The most common postoperative complications were fever of unknown origin (14.8%) and acute chest syndrome (11.1%). After splenectomy there was a significant increase in leukocytes, neutrophils, and platelets, the latter two parameters remained significantly elevated when compared with non-splenectomized patients. There was no difference in the incidence of clinical events, except hepatic sequestration, which was more common in splenectomized patients. CONCLUSION: Partial splenectomy was a safe procedure in patients with sickle cell disease. There were no differences in the clinical picture in children splenectomized and non-splenectomized except the greater frequency of hepatic sequestration crisis in the first group
