Watch this detailed video on Splenectomy, a surgical procedure to remove the spleen. In this video, we cover indications, surgical techniques, preoperative preparation, and postoperative care. Perfect for medical students, healthcare professionals, and anyone interested in understanding this procedure.

Anecdotal reports of splenectomy date back to the 16th century and by 1920 the Mayo Clinic had reported on splenectomy with operative mortality rates of about 10%. Deletaire originally described laparoscopic splenectomy, in 1991. The laparoscopic approach should be considered as a therapeutic option for all patients undergoing elective splenectomy. A few important contraindications to the laparoscopic approach are patients with liver failure with portal hypertension, ascities or unmanageable coagulopathy. In addition, while laparoscopic management of splenic trauma has been reported in the literature, it is not standard of care, and should not be considered in a patient with hemodynamic instability. It is very important to understand the vascular anatomy of the spleen when planning a splenectomy. The majority of the arterial supply is from the splenic artery, which is one of three major branches off the celiac axis of the aorta. The splenic artery has a serpentine course that crowns the superior boarder of the pancreas. It generally gives off a few pancreatic branches and a branch to the superior pole of the spleen prior to diving into the splenic hilum.

A splenectomy is a surgical procedure involving the removal of the spleen, an organ located in the upper left part of the abdomen. Though small in size, the spleen plays a crucial role in the body’s immune system by filtering blood, recycling old red blood cells, and storing white blood cells and platelets. Removal of this organ may be necessary due to trauma, disease, or blood disorders.

Indications for Splenectomy
Splenectomy is usually performed when the spleen is causing more harm than good, or when it is damaged. Common indications include:

1. Trauma: A ruptured spleen due to an accident or injury can cause internal bleeding, making emergency splenectomy life-saving.

2. Blood Disorders: Conditions like idiopathic thrombocytopenic purpura (ITP), hereditary spherocytosis, or thalassemia may require spleen removal.

3. Enlarged Spleen (Splenomegaly): Enlarged spleens due to infections, liver disease, or cancers can lead to anemia, fatigue, or increased risk of rupture.

4. Cancer: Lymphomas or leukemia sometimes involve the spleen and necessitate removal.

5. Infections or Cysts: Persistent infections, abscesses, or cysts in the spleen that do not respond to medical treatment may require surgical intervention.

Types of Splenectomy
Splenectomy can be performed using two main techniques:

1. Open Splenectomy:

   • Traditional method involving a large incision in the abdomen.

   • Often used in cases of severe trauma or very large spleens.

2. Laparoscopic (Minimally Invasive) Splenectomy:

   • Involves small incisions and the use of a camera and specialized instruments.

   • Advantages include less postoperative pain, faster recovery, and smaller scars.

Procedure Overview

• Preparation: Patients undergo blood tests, imaging studies, and vaccinations to reduce the risk of infections post-surgery.

• Surgery: Under general anesthesia, the surgeon carefully separates the spleen from surrounding tissues and blood vessels before removing it.

• Recovery: Hospital stay varies from 2–7 days depending on the type of surgery. Patients may need to take antibiotics temporarily and avoid heavy physical activity for a few weeks.

Risks and Complications
As with any surgery, splenectomy carries certain risks:

• Bleeding or infection at the surgical site

• Blood clots

• Injury to nearby organs (stomach, pancreas, or colon)

• Increased susceptibility to infections, particularly from encapsulated bacteria like Streptococcus pneumoniae, Haemophilus influenzae, and Neisseria meningitidis

Post-Splenectomy Care

1. Vaccinations: Before or soon after surgery, patients are usually given vaccines against pneumococcus, meningococcus, and Haemophilus influenzae.

2. Antibiotics: Some patients require prophylactic antibiotics to prevent infections.

3. Lifestyle Adjustments: Patients should promptly report fever or signs of infection and maintain regular follow-ups with their physician.

Conclusion
Splenectomy is a critical surgical procedure that can save lives and alleviate serious health conditions. Modern surgical techniques, especially laparoscopic methods, have made the procedure safer with quicker recovery. However, patients need to remain vigilant about their increased infection risk and follow post-surgical guidelines carefully.
