Indications for and results of splenectomy in different hematological disorders

The objective of this retrospective study was to determine the indications for splenectomy in hematological disorders and to analyze the results depending on the indication leading to surgery. Fifty-six patients with various hematological disorders were splenectomized between 1990 and 1994. The main indication was noted. Operative success was defined as: return to normal platelet counts without further medication in thrombocytopenia, relief of pain and local compression syndrome in painful splenomegaly, hemoglobin levels > 10 g/dl without the need for further transfusions in hemolytic anemia, response to chemotherapy after splenectomy for prior resistance because of massive splenic infiltration, and relief of infection in splenic infection. Morbidity and mortality were noted. Five major indications for splenectomy were found: thrombocytopenia (n = 36, success 78%), painful splenomegaly (n = 8, success 100%), hemolytic anemia (n = 5, success 60%), resistance to chemotherapy because of massive splenic infiltration (n = 5, success 100%). One patient with thrombocytopenia died (mortality 2%). Seven patients had major complications (13%). In hematological diseases, thrombocytopenia, painful splenomegaly and splenic infection are likely to be improved by splenectomy. In hemolytic anemia it can be a helpful approach, while in resistance to chemotherapy because of massive splenic infiltration success is less likely.
