Splenectomy (Open, Laparoscopic, Robotic)

Two very different operations under one name. The elective splenectomy (ITP, hereditary spherocytosis, lymphoma staging) is a controlled, laparoscopic-first case built around early hilar control. The trauma splenectomy is a damage-control decision point — most blunt splenic injuries never see the OR at all, so knowing when nonoperative management fails is as important as the operative steps. See Trauma topic review and Exploratory Laparotomy for Trauma for the surrounding trauma-survey context.

Procedure Snapshot

Indication: ITP refractory to medical therapy, hereditary spherocytosis, lymphoma/myeloproliferative staging, splenic abscess or cyst — and trauma (blunt or penetrating splenic injury failing nonoperative management or presenting unstable).
Expected duration: ~1–2 hr laparoscopic/robotic elective; trauma splenectomy is as fast as hemostasis allows (minutes, in extremis).
Special instruments: Laparoscopic/robotic stapler, specimen retrieval bag, energy device for short gastrics, Kittner/vessel loops for hilar control; open trauma case adds vascular clamps and a rapid infuser.

Step Workflow

Elective (Laparoscopic/Robotic)

Position: Right lateral decubitus (left side up), bump under the flank.
Ports: Camera + 2–3 working ports along the left subcostal margin.
Divide the splenocolic and splenophrenic ligaments first to mobilize the inferior/lateral spleen.
Divide the short gastric vessels along the greater curvature (energy device) — stay close to the spleen to protect the gastric wall.
Approach the hilum last; take the splenic artery and vein with a vascular stapler load.
Inspect the lesser sac and gastrosplenic/splenorenal ligaments, pancreatic tail, and hilum for accessory spleens — remove if found (relevant for ITP).
Extract the spleen in a retrieval bag, morcellating if needed for benign disease (avoid morcellation if malignancy is a concern).

Trauma (Open, Emergent)

Identified during the systematic trauma survey (see Exploratory Laparotomy for Trauma) — usually after four-quadrant packing.
Divide splenocolic, splenorenal, and splenophrenic ligaments to mobilize the spleen medially into the wound.
Control the hilum early with a hand or clamp if actively hemorrhaging — don’t chase individual bleeding vessels in an unstable patient.
Ligate/staple the splenic artery and vein together at the hilum; complete splenectomy.
Inspect the pancreatic tail for injury before closing — it runs directly into the hilum and is the most common associated injury.

Nonoperative Management vs Operating (Blunt Splenic Injury)

Hemodynamically stable → nonoperative management is first line regardless of grade: ICU/monitored bed, serial hemoglobin, bed rest.
Contrast blush on CT in a stable patient → angioembolization, not automatic splenectomy.
Hemodynamically unstable, or ongoing transfusion requirement despite resuscitation → OR.
Failure of nonoperative management (dropping hemoglobin, new instability) is far more common in higher-grade injuries, but grade alone doesn’t mandate surgery in a stable patient.
Spleen-sparing (partial splenectomy, mesh wrap, topical hemostatics) can be considered in stable patients, especially children, when technically feasible.

Rapid-Fire Questions

Q: Vaccines post-splenectomy?
A: Pneumococcal, meningococcal, H. influenzae type B.
Q: When do you give them?
A: 2 weeks post-op if elective/scheduled (better immune response); if emergent/trauma, give prior to discharge since follow-up isn’t guaranteed.
Q: Accessory spleen locations?
A: Splenic hilum, gastrosplenic ligament, pancreatic tail (PMID 30146412).
Q: Stable patient, CT shows a Grade IV splenic laceration with a contrast blush — next step?
A: Angioembolization, not automatic splenectomy — grade alone doesn’t dictate operative management.
Q: What organism is the classic culprit in OPSI?
A: Encapsulated organisms — Strep pneumoniae is most common; also H. influenzae and N. meningitidis.
Q: Distal pancreatic injury with ductal involvement on trauma laparotomy — management?
A: Distal pancreatectomy with splenectomy (spleen-sparing can be considered in stable children).

Critical Anatomy

Landmarks: Splenic hilum (artery/vein), splenocolic/splenorenal/splenophrenic/gastrosplenic ligaments, short gastric vessels, pancreatic tail.
Danger zones: Splenic vein injury during hilar dissection; pancreatic tail injury (runs into the hilum — most common iatrogenic injury during splenectomy); gastric wall injury during short gastric division.

Risks: Bleeding, pancreatic fistula/injury to the tail, gastric injury, subphrenic abscess, and overwhelming post-splenectomy infection (OPSI) — lifelong risk, highest in the first 2–3 years and in children.
Benefits: Definitive control of hemorrhage (trauma) or correction of the underlying hematologic disease (elective).
Alternatives: Nonoperative management/angioembolization (trauma); medical therapy or partial splenectomy (elective, select cases).

Post-Op Considerations

Vaccinate: pneumococcal, meningococcal, Hib — 2 weeks post-op if elective, prior to discharge if emergent.
Lifelong infection precautions — patient education on OPSI, low threshold for antibiotics/medical attention with fever, consider daily penicillin prophylaxis in young children.
Watch platelet count — reactive thrombocytosis is common; consider prophylactic anticoagulation if platelets rise markedly (>1,000,000) or with additional VTE risk factors.
Trauma patients: monitor for delayed splenic bleeding or missed pancreatic tail injury.

Quick Reference Table — AAST Spleen Injury Grading (2018 Revision)

Grade	Parenchymal Injury	Vascular Injury
I	Subcapsular hematoma <10% SA; laceration <1 cm depth	None
II	Subcapsular hematoma 10–50% SA; laceration 1–3 cm	None
III	Subcapsular hematoma >50% SA or ruptured; laceration >3 cm or involving trabecular vessels	Any splenic vascular injury contained within capsule
IV	Laceration involving segmental or hilar vessels producing >25% devascularization	Active bleeding contained within capsule
V	Shattered spleen	Hilar vascular injury with devascularized spleen; active bleeding beyond the capsule

SA = surface area. Grade drives imaging follow-up and risk stratification, not by itself the decision to operate — that's driven by hemodynamics.

Quick-Reference Cards

Nonop vs OR — the decision tree

Stable, no blush
Nonop management — monitor, serial H/H.
Stable, blush on CT
Angioembolization.
Unstable, or ongoing transfusion need
OR — splenectomy (or splenorrhaphy if feasible and stable enough).
Grade alone
Does not mandate surgery — hemodynamics drive the decision.

Post-splenectomy vaccine/infection bundle

Vaccines
Pneumococcal, meningococcal, Hib.
Timing
2 weeks post-op if elective; before discharge if emergent/trauma.
OPSI organisms
Encapsulated: S. pneumoniae (most common), H. influenzae, N. meningitidis.
Highest-risk period
First 2–3 years post-splenectomy; lifelong risk remains.

Trauma splenectomy — bail-out plan

Unstable/exsanguinating
Hand/clamp control of hilum first — don't chase individual vessels.
Pancreatic tail
Inspect before closing — most common associated injury.
Distal pancreatic duct injury
Distal pancreatectomy + splenectomy (spleen-sparing in stable children).
