Splenectomy

Splenectomy

A splenectomy is a surgical procedure to remove the spleen, an organ located in the upper left side of the abdomen, just below the rib cage. The spleen plays a role in filtering blood, recycling old red blood cells, and supporting the immune system by producing white blood cells and storing platelets.

Indications

A splenectomy is typically performed for the following reasons:

• • Ruptured spleen: Often caused by trauma, a ruptured spleen can lead to life-threatening internal bleeding.
• • Blood disorders: Conditions like hereditary spherocytosis, sickle cell disease, or idiopathic thrombocytopenic purpura (ITP) may require splenectomy to manage symptoms.
• • Cancer: Certain cancers, such as lymphoma or leukemia, can affect the spleen, necessitating its removal.
• • Infections or abscesses: Severe infections or abscesses in the spleen may require surgical removal.
• • Enlarged spleen (splenomegaly): When the spleen becomes enlarged due to various diseases, it may need to be removed if it causes discomfort or other health issues.

Procedure

There are two main types of splenectomy:

• • Laparoscopic splenectomy: A minimally invasive procedure where the surgeon makes several small incisions and uses a laparoscope (a small camera) to guide the removal of the spleen. This method usually results in quicker recovery, less pain, and smaller scars.
• • Open splenectomy: In cases where the spleen is significantly enlarged or if there are complications, an open surgery with a larger incision may be necessary.

The surgery typically takes 1 to 2 hours, and most patients can go home within a few days, depending on the type of surgery and their overall health.

Recovery

Recovery from a laparoscopic splenectomy is generally faster than from an open procedure, with most patients resuming normal activities within a few weeks. Patients are advised to avoid heavy lifting and strenuous activities during the recovery period. Following surgery, patients may need vaccines to prevent infections, as the spleen plays a role in fighting certain bacteria.

Risks and Complications

While splenectomy is generally safe, it carries some risks, including infection, bleeding, and injury to surrounding organs. The most significant long-term risk is an increased susceptibility to infections, particularly from bacteria such as Streptococcus pneumoniae, Haemophilus influenzae, and Neisseria meningitidis. Patients may require vaccinations and possibly long-term antibiotics to help prevent infections.

Outlook

Most people live healthy lives after a splenectomy, though they may need to take precautions to avoid infections. The liver and other organs typically compensate for the loss of the spleen's functions, allowing the body to continue filtering blood and fighting infections, albeit with some added risk.

Prevention of Infections

After a splenectomy, patients should stay up-to-date with vaccinations, practice good hygiene, and seek medical attention promptly if they develop a fever or signs of infection. Wearing a medical alert bracelet and informing healthcare providers about the splenectomy are also important for proper management in case of emergencies.
