A comparison between a series of splenectomies performed at the University of Virginia Medical Center for hematologic disorders between 1946 and 1962 (Series I) and 1963 and 1982 (Series II) is presented. Four hundred splenectomies (20 per year) were performed between 1963 and 1982 compared with 94 (5.5 per year) between 1946 and 1962. Also noted in Series II was a sharp decline in the number performed each year between 1974 and 1983. The major factor responsible for these observations was the evolution of the staging laparotomy for malignant lymphomas, particularly Hodgkin's disease, and the decline in the average annual incidence of staging laparotomies since 1974. Staging laparotomy currently is rarely done for non-Hodgkin's lymphomas. Also contributing to the changes noted was an increase in the total number but subsequent fall in the annual incidence of splenectomy for hereditary spherocytosis, idiopathic hypersplenism, and myeloproliferative disorders in Series II. The average number of splenectomies for idiopathic thrombocytopenic purpura increased from 1.1 per year in Series I to 3.6 per year in Series II; the annual incidence during the study period of Series II, however, remained constant. The total number of splenectomies for hairy cell leukemia and Felty's syndrome increased from zero in Series I to 12 and 17, respectively, in Series II, whereas the number of miscellaneous reasons dropped from 29 (1.7 per year) in Series I to 15 (0.75 per year) in Series II. The mortality rate in Series I was 6.3% compared with 4.0% in Series II. No deaths occurred in Series II after 1979. Indications for splenectomy in Series II were for diagnostic purposes in 3.2%, therapeutic in 56.5%, staging in 39.5%, and restaging in 0.8%. Accessory spleens were found in 49 (12.5%) in Series II. |
