The aim of this work was to report our own clinical experience and to compare it our results with those already published. This is a retrospective study of 70 splenectomies performed for hematologic diseases at the service des urgences viscerales of Ibn Rochd teaching hospital of Casablanca, between 1996 and 2001. The study included 70 patients. Splenectomy was performed for therapeutic reasons by laparotomy in 56 cases (80%) and bym laparoscopy in 14 cases (20%). The post-operative after-effects were mild in 81.4%. A patient died, however of pulmonary embolism. Splenectomy is an important tool in the management of patients suffering from hemolytic anemia, auto-immune thrombopenic purpura and other hemolytic anemias. Management by a multidisciplinary team is required to prevent a maximum of long and short-term post-operative complications and to offer the offer the best conditions for a successful splenectomy.
