title: Hematological and oncological indications for splenectomy in children.
abstract: The most common hematologic and oncologic indications for splenectomy in childhood are hereditary spherocytosis, chronic idiopathic thrombocytopenic purpura, hypersplenism, and Hodgkin's disease. Because of the increased incidence of septic complications after splenectomy, benefits to be gained from the operation should be weighed against the risks. A retrospective study was done on the charts of 42 consecutive children with hematologic and oncologic disorders, who underwent splenectomy between 1967 and 1982. The incidence of septic complications after splenectomy was 12%; sepsis, however, only occurred in patients with severe underlying diseases (three patients with Hodgkin's disease, one patient with systemic lupus erythematosus, and one patient with chronic pseudo-malignant immunoproliferation). In contrast, none of the patients who were splenectomized for other reasons (mainly hereditary spherocytosis and chronic immune thrombocytopenic purpura) had a septic complication. Two patients with end-stage Hodgkin's disease (5%) experienced fatal septic complications. Although splenectomy is well established for diagnostic and therapeutic considerations in patients with Hodgkin's disease, not all of them might benefit from this operation, and studies with a more limited approach to splenectomy might prove to be of the same therapeutical value.
