Patients, both adults and children, with various haematological disorders who had splenectomy electively in the diagnosis, staging or treatment of their condition during a 15-year period in the Aberdeen hospitals were reviewed. The outcome regarding the disease and the immediate and long-term complications of splenectomy in this group of 185 patients are presented. Splenectomy has an acceptably low morbidity, even in patients with serious haematological disease, in the hands of an experienced surgical team, where there is close co-operation between surgeon and haematologist. Occasionally, late overwhelming infections may occur, despite prophylaxis with penicillin and pneumococcal vaccination. It seems likely that, in their zeal to report such hazards, authors may allow the pendulum against splenectomy to swing too far, in the direction of leaving patients, especially adults, with considerable symptoms and poor health, rather than risk the occasional consequences of the asplenic state.
