Splenectomy is the surgical removal of the spleen. The spleen is an organ in the upper left part of the abdomen. It is beneath the ribs and behind the stomach. The spleen filters blood to remove bacteria, parasites, and other organisms that can cause infection. It also removes old and damaged blood cells.
