A splenectomy is a surgical procedure that involves the removal of the spleen, an organ located in the upper left part of the abdomen. The spleen plays a role in filtering blood and supporting the immune system. This surgery may be necessary due to conditions such as trauma, tumors, or certain blood disorders. After a splenectomy, patients may be at a higher risk for infections since the spleen helps fight bacteria. Therefore, doctors often recommend vaccinations and antibiotics to help protect against infections. Recovery typically involves a few weeks of rest and monitoring for any complications.
