Splenectomy is a surgery performed to remove the affected or damaged spleen. The spleen is the organ that lies beneath the rib cage attached to the left side of the abdomen. The spleen is an important organ as it eliminates the dead, damaged or old blood cells from the body. It also helps in fighting against foreign bodies (infections) and filtering unwanted substances from the body. Although most of the blood products are produced by the bone marrow, the spleen also produces a certain type of blood cells and white blood cells. The main reason for Splenectomy surgery is an abdominal injury and it is performed in order to treat the ruptured spleen. Splenectomy is also helpful in treating various other conditions like splenomegaly (enlarged spleen), some cancers, certain blood disorders, and benign tumors or cysts. These days the surgical procedure of splenectomy is often performed by a minimally invasive technique known as laparoscopic splenectomy. This involves a tiny camera and special surgical instruments.
