[Partial splenectomy in thalassemia major. Apropos of 19 cases]

Nineteen cases of B Thalassemia have benefited from partial splenectomy at the General Surgery Service of Farhat Hached Hospital in Sousse (Tunisia). The partial splenectomy indication was to reduce hypersplenism, thus transfusion needs, to suppress splenic pain and to conserve a splenic remnant, which preserves patients' immunity. The operation was in reality a subtotal splenectomy keeping the lower pole in all cases. We had no per-operatory complication. The preoperatory bleeding was not more serious than in total splenectomy. In all the patients, we noticed reduction of about half the transfusion need, except one who had also a chronic deficit in glyco-six phospho-dehydrogenase. The average hemoglobin rate increased from 60 g/L in the pre-operatory to 80 g/L after the operation. Consequently, this reduction of transfusion needs results in the decrease of the hemochromatosis, which is one of the main complications of hypertransfused thalassemia.
