Splenectomy is a surgical procedure to remove your spleen. The spleen is an organ that sits under your rib cage on the upper left side of your abdomen. It helps fight infection and filters unneeded material, such as old or damaged blood cells, from your blood.
The most common reason for splenectomy is to treat a ruptured spleen, which is often caused by an abdominal injury. Splenectomy may be used to treat other conditions, including an enlarged spleen that is causing discomfort (splenomegaly), some blood disorders, certain cancers, infection, and noncancerous cysts or tumors.
