A man involved in a traffic accident is rushed to the emergency room of a hospital with severe internal bleeding. Examination reveals a ruptured spleen. What is the treatment of choice and what is the likely long-term outcome (prognosis)?
What will be an ideal response?
Splenectomy is not as necessary as once believed, and is now performed less frequently. If the spleen does need to be removed, the prognosis is very good, as the functions of the spleen are taken over by the liver and bone marrow.
