How Common Are Splenectomies?

Although preservation of the spleen following abdominal trauma and spleen-preserving surgical procedures have become gold standards, about 22,000 splenectomies are still conducted annually in the USA. Infections, mostly by encapsulated organisms, are the most well-known complications following splenectomy.

Does a splenectomy affect life expectancy?

Although the series of patients is small, it seems that splenectomy did not have an adverse effect on life expectancy. The haematological status and the quality of life improved after splenectomy in 17 of 19 patients.

Is spleen removal common?

Up to 30% of people have a second spleen (called an accessory spleen). These are usually very small, but may grow and function when the main spleen is removed. Rarely, a piece of the spleen may break off with trauma, such as after a car accident. If the spleen is removed, this piece can grow and function.
