Splenectomy

Indications

  1. Elective
    • Haematological disorders
    • Part of radical upper abdominal surgery
    • Splenic tumours
    • (Previously - staging of lymphoma)
  2. Emergency
    • Trauma

Preparation

  1. GA
  2. NGT
  3. Antibiotics
  4. DVT prophylaxis
  5. Supine position
  6. Vaccination against streptococcus pneumoniae 6/52 before elective surgery and ASAP post-operatively in emergency splenectomy
  7. + Long-term prophylaxis against pneumococcal sepsis (with PenV - 250mg bd)

Elective Procedure
(remove spleen and look for speniculi)

  1. Incision
    • Left paramedian
    • Midline: for trauma
    • Transverse
    • Left subcostal
  2. Divide lienorenal ligament - attaches spleen to kidney
    • (stand on right of patient)
    • Pass hand over spleen onto lienorenal ligament
    • Retract spleen and divide - start from lower end and move towards apex/upper pole using long scissors (obviously!)
    • Deliver spleen up into wound (sweep away peritoneum with swab on a stick)
  3. Detach omentum from lower pole of spleen
    • Divide left gastroepiploic vessles between artey forceps + ligation with ties
  4. Ligate main splenic vessels
    • Pass fingers around hilum and palpate branches of splenic artery as they pass into spleen; clip + divide branches
    • Remove artery before the vein (if you don't - blood can enter but not leave and you end up in a bloody mess from an exploded spleen) - removing artery "deflates" the spleen
    • (Protect tail of pancreas), left colic flexure and diaphragm
  5. Detach gastrosplenic ligament
  6. Remove spleen + place suction drain in subphrenic space
  7. Close abdominal wall in layers

Emergency splenectomy
(Aim to preserve spleen if possible - prevents post op splenic sepsis)
IV access, resuscitate
Correct coagulopathy
Cross match lots of blood (4+ units)

  1. Evacuate clots (manually + suction)
  2. Pass hand down to hilum to control bleeding
  3. Assess degree of splenic damage
    • Minor decapsulating injury - managed by application of topical haemostatic agents + wrapping spleen in absorbable mesh
    • Single laceration: suture (splenorrhapy)
    • Complete/partial avulsed fragment: partial splenectomy - divide splenic vessels supplying pole in question, resect the fragment and oversew edge with absorbable mattress sutures
    • Massive irreprable damage: splenectomy
  4. Close abdomen

Complications of splenectomy

  1. General
    • Bleeding
    • Atelectasis of lower lobe
    • Ischaemic perforation of greater curvature of stomach
    • Wound infection / subphrenic abscess
    • Damage to organs causing gastric fistula, pancreatitis, pancreatic fistula
  2. Specific
    • Thromobcythaemia (strokes, clots) + leucocytosis - commence aspirin 300mg daily if platelets >750
    • Infection from encapsulated organisms
