The authors extirpated the splenic cyst of a young girl with the use of stapler in such a way that the distal part of the spleen was preserved. During this case the types of splenic preservative operations and the question of fulminant sepsis found in the patients went under splenectomy were surveyed. According to us the advantage of using stapler in partial splenectomy than the others is that firstly it is technically simple, less time consuming, and the haemostasis is safe. This is thought to be a valuable additional procedure to the ultimately known and the procedures which are used.
