Segmental Splenectomy in Schistosomiasis

摘要

Segmental splenectomy was performed in 5 patients with hepatosplenic schistosomiasis mansoni and symptomatic splenomegaly. The aim was to preserve a functional remnant comprising 20-30 per cent of the bulk of a greatly enlarged spleen. The operative technique involved devascularization of anatomic segments and suture of an omental patch to the residual spleen. This procedure was simple, well tolerated and effective in relieving abdominal discomfort and cytopenias. The residual spleens showed normal uptake of 99Tc-sulphur colloid. If long term observation confirms the value of segmental splenectomy in hepatosplenic schistosomiasis, it may become appropriate therapy for those patients with symptomatic splenomegaly who do not require portal decompression.
