Splenectomy

What Splenectomy Means in Everyday Medical Language

Splenectomy is a surgery to remove the spleen, an organ located in the upper left side of the abdomen near the stomach. The spleen helps filter the blood by removing old or damaged red blood cells and plays a key role in the immune system by helping the body fight certain infections. It also stores blood cells like platelets and iron. Sometimes, the spleen can become enlarged or damaged due to injury, blood disorders, or cancer, and removing it may be necessary to improve health or manage symptoms.

Why Splenectomy Can Matter in Cancer Care

In cancer care, splenectomy may be considered when the spleen is enlarged or causing problems, such as in blood disorders like myelofibrosis or certain lymphomas and leukemias. An enlarged spleen can cause symptoms like abdominal discomfort or anemia by trapping blood cells. Removing the spleen can help relieve these symptoms and improve blood counts. Additionally, splenectomy may be part of treatment plans involving stem cell or bone marrow transplants, where the immune system and blood cell production are closely managed. Because the spleen helps fight infections, its removal requires careful planning to reduce infection risks.

What Patients Might See, Feel, or Hear About Splenectomy

Patients may hear about splenectomy when discussing treatment options for blood cancers, blood disorders, or after trauma to the abdomen. Doctors may explain that the surgery can help with symptoms caused by an enlarged spleen or improve blood cell production. Patients might be told about the need for vaccines before or after surgery to protect against infections. Recovery involves hospital stay and monitoring for complications. Understanding why the spleen is removed and how it affects the body can help patients feel more prepared and involved in their care.

Risks and Precautions After Splenectomy

Because the spleen plays an important role in fighting certain bacteria, removing it increases the risk of serious infections, sometimes called overwhelming post-splenectomy infection (OPSI). To reduce this risk, patients usually receive vaccines against bacteria like Streptococcus pneumoniae, Haemophilus influenzae, and Neisseria meningitidis. Patients are also advised to seek medical care promptly if they develop signs of infection. Doctors may monitor blood counts after surgery, as platelet levels can rise, increasing the risk of blood clots. Understanding these risks helps patients take precautions and follow their care team's recommendations.

How to Use This Information and Next Steps

Learning about splenectomy can help patients and caregivers ask their healthcare team important questions, such as why the surgery is recommended, what to expect during recovery, and how to prevent infections afterward. This information is educational and does not replace personalized medical advice. If splenectomy is mentioned in your care, the best next step is to discuss with your doctor or nurse how it applies to your specific situation, including benefits, risks, and follow-up care.
