The effects of splenectomy in the treatment of chronic idiopathic thrombocytopenic purpura (ITP) were analysed in 177 subjects (118 adults and 59 children) operated upon between two and 25 years earlier. In 145 patients, thrombocytopenia regressed immediately or within 2 months after the operation. Regression of thrombocytopenia later during follow up was observed in a further 14 cases. Recurrence of thrombocytopenia after good immediate result of splenectomy developed in 32 patients. In 13 cases the recurrence was transient but in the remaining 19 patients it was long-lasting. In these cases presence of accessory spleens was suggested by the absence of Howell-Jolly bodies in the peripheral blood smear and demonstrated by splenic scan in 16 cases, and confirmed in 13 out of 15 splenectomized patients. Resplenectomy caused in 12 patients permanent disappearance of thrombocytopenia.

The study is based on a material of 60 patients with chronic lymphocytic leukaemia of mild course with survival over 4 years. The method used was a comparison of the patients treated from the time of diagnosis establishment with the group of similar patients not treated throughout the whole period of follow-up and with another group of patients treated from the time of exacerbation of the proliferative process. The following data were taken into account: survival length, degree of splenomegaly and lymphadenopathy, leucocyte and platelet counts, haemoglobin level, infectious complications. It was demonstrated that cytostatic and/or hormonal treatment started at the time of diagnosis establishment did not prolong the survival. A statistically significant prolongation of survival time was observed, on the other hand, in cases treated from the time of exacerbation. Cytostatic agents increased the risk of infections and the risk of thrombocytopenia.
