Abstract
During the 9-year period 1968–76 116 splenectomies were performed at the General Hospital, Nottingham. Of these, 13 (11 per cent) were undertaken for unexplained splenomegaly. In 6 patients a diagnosis was established by the operative procedure (2 with sarcoidosis, 2 splenic cysts, 1 Gaucher's disease and 1 haemangiosarcoma). Histological examination of the excised spleens in the remaining 7 patients showed no specific features. Two of these patients benefited considerably from removal of very large spleens. Another patient died from lymphosarcoma which was diagnosed 21 months after splenectomy. In the remaining 4 patients with mild to moderate splenomegaly, there were no real diagnostic or therapeutic advantages. It is concluded that splenectomy should always be considered in patients with unexplained moderate or gross splenomegaly but it may not be helpful in the patient whose spleen is only mildly enlarged.
