1. What is it? Any common name for this procedure?
A robotic-assisted splenectomy is a minimally invasive surgery to remove the spleen, an organ located in the upper left side of the abdomen that filters blood and supports the immune system. Using a robotic platform, the surgeon operates through several small incisions (usually 8mm to 12mm) rather than one large "open" incision under the ribcage.
The robot’s 3D visualization is particularly beneficial for splenectomies because the spleen is highly vascular and sits near the "tail" of the pancreas; the precision of the robot helps avoid accidental injury to these surrounding structures.
Common Names:
- Robotic Splenectomy
- Minimally Invasive Splenectomy
2. Common Indications: When is it Recommended?
Splenectomy is performed when the spleen becomes a threat to health or is damaged beyond repair.
- Blood Disorders: Conditions where the spleen destroys too many healthy blood cells (e.g., ITP).
- Splenomegaly: An enlarged spleen that causes pain, a feeling of fullness, or a high risk of rupture.
- Spleen Cysts or Tumors: Whether benign or malignant.
- Splenic Artery Aneurysm: A bulge in the artery supplying the spleen that may require the removal of the organ for safety.
- Trauma: While often managed with open surgery in emergencies, a robotic approach may be used if a patient is stable after a minor injury.
3. List of Associated Diseases and Conditions
- Immune Thrombocytopenic Purpura (ITP): An autoimmune disorder where the spleen destroys platelets.
- Spherocytosis or Sickle Cell Anemia: Genetic conditions where the spleen filters out misshapen red blood cells too aggressively.
- Lymphoma: Certain types of blood cancer that may involve or originate in the spleen.
- Splenic Abscess: A localized infection in the spleen that does not respond to antibiotics.
4. List of Screening Tests and Assessment Tools
Before surgery, the surgical team must assess the size of the spleen and the patient's blood counts.

Tool
|
Purpose
|
|
CT Scan / MRI
|
Essential for measuring the spleen's dimensions and checking its proximity to the pancreas and stomach.
|
|
Complete Blood Count (CBC)
|
To check levels of red cells, white cells, and especially platelets.
|
|
Ultrasound
|
A quick way to monitor the size of the spleen over time.
|
|
Bone Marrow Biopsy
|
Sometimes performed before surgery to ensure the blood disorder is originating in the spleen and not the bone marrow.

5. Am I Eligible for This Evaluation?
- Spleen Size: While the robot can handle large spleens, "massive splenomegaly" (usually over 20–25 cm) may occasionally require a traditional open surgery for safe extraction.
- Blood Stability: Patients with extremely low platelets may need a transfusion immediately before or during surgery to prevent bleeding.
- No Recent Rupture: If the spleen has already ruptured and the patient is bleeding internally, a traditional open emergency surgery is standard.
6. Pre and Post Care
Pre-Care (Immunizations):
- The "Splenectomy Bundle": Because the spleen is vital for fighting certain bacteria, patients must receive vaccinations (specifically for Pneumococcus, Meningococcus, and Haemophilus influenzae) at least 2 weeks before surgery.
Post-Care (The Recovery):
- Activity Restrictions: No heavy lifting or contact sports for 4–6 weeks to prevent internal injury while healing.
- Long-term Antibiotics: Some patients may need a daily low-dose antibiotic or a "rescue" supply to keep at home in case of a fever.
- Medical Alert: Patients are encouraged to wear a medical alert bracelet stating they are "asplenic" (without a spleen) to ensure rapid treatment for future infections.
7. Days Required for Hospitalization
- Surgical Time: 1.5 to 3 hours.
- In-Hospital Stay: 1 to 2 Days. Many patients are discharged within 24 hours once their blood counts are stable and pain is controlled.
- Full Recovery: Return to work in 2 weeks; full activity in 4 to 6 weeks.
- Hospitalization: 1–2 Days.
8. Benefits of the Robotic Approach
- Pancreatic Protection: The tail of the pancreas sits right against the "hilum" (entry point) of the spleen. The robot's 10x magnification helps the surgeon separate these organs without causing a "pancreatic leak."
- Handling of Accessory Spleens: About 15% of people have small "extra" spleens. The robotic camera makes it much easier to find and remove these, which is critical for curing blood disorders like ITP.
- Minimal Blood Loss: The robot’s precision in clipping and sealing the splenic artery and vein reduces the need for transfusions.
- Cosmetic and Recovery Benefits: 3–4 small incisions result in significantly less pain and a faster return to daily life than a large open incision.
