Palliative Surgical Interventions

Palliative Surgery Goals & Selection - Setting the Stage

• Core Goals:
  • Alleviate distressing symptoms (e.g., pain, obstruction, bleeding).
  • Enhance Quality of Life (QoL ↑).
  • Primarily comfort-oriented, NOT curative.
• Crucial Selection Criteria (📌 Mnemonic: S.C.A.R.E.M.):
  • Severe symptoms from incurable cancer.
  • Consent from patient & alignment with wishes.
  • Acceptable Performance Status (PS) (e.g., ECOG ≤ 2-3).
  • Reasonable life expectancy (> surgical recovery, e.g., > 4-6 weeks).
  • Expected benefits outweigh surgical risks/burden.
  • Multidisciplinary Team (MDT) agreement essential.

⭐ The "appropriateness" of palliative surgery hinges on a realistic balance between potential symptom relief, QoL improvement, and the patient's overall condition and prognosis.

Palliative Procedures: Obstruction & Bleeding - The Plumber's Toolkit

• Goal: Symptom relief (pain, vomiting), ↑QoL; not curative.
• Obstruction Management:

  • GI Tract (Malignant Obstruction):

    • Stenting: Esophageal, duodenal, colonic (SEMS common).
    • Surgical Bypass: Gastrojejunostomy (GOO), colostomy/ileostomy.
    • Venting Gastrostomy/Jejunostomy: For decompression.

  • Biliary Tract (Obstructive Jaundice):

    • Stenting: Via ERCP (preferred) or PTC.
    • Surgical Bypass: E.g., choledochojejunostomy.

  • Urinary Tract:

    • Percutaneous Nephrostomy (PCN).
    • Ureteric Stents (e.g., DJ stent).
• Bleeding Management (Tumor-related):
  • Endoscopic Hemostasis: Injection, clips, APC.
  • Angioembolization.
  • Palliative Radiotherapy (RT).
  • Surgical Ligation/Resection: Limited role.

  ⭐ Self-Expanding Metal Stents (SEMS) are a cornerstone for palliating malignant GI obstruction, offering rapid symptom relief and improved oral intake.

Palliative Procedures: Pain & Other Symptoms - Targeted Comfort

• Pain Management:
  • Nerve Blocks:
    • Celiac plexus block (e.g., pancreatic cancer pain).
    • Intercostal nerve block (chest wall pain).
  • Neuroablative Procedures:
    • Cordotomy (chemical/percutaneous for intractable unilateral pain, typically below C5).
    • Rhizotomy (selective nerve root destruction).
  • Intrathecal Drug Delivery: Pumps for morphine, ziconotide.
• Malignant Effusions:
  • Pleural Effusion:
    • Therapeutic thoracentesis.
    • Pleurodesis (talc preferred, bleomycin, doxycycline) to prevent reaccumulation.
    • Indwelling Pleural Catheter (IPC) for ambulatory drainage.
  • Malignant Ascites:
    • Large-volume paracentesis.
    • Indwelling peritoneal catheter for recurrent ascites.
• Other Symptom Control:
  • Fungating Wounds: Debridement, odor control (metronidazole), specialized dressings.
  • Pathological Fractures: Prophylactic/therapeutic internal fixation, vertebroplasty/kyphoplasty for spinal stability.

    ⭐ Celiac plexus neurolysis (CPN) can provide significant pain relief in 70-90% of patients with unresectable pancreatic cancer pain.

Palliative Surgery Decision Making & Ethics - Guiding Choices

• Goal: Improve Quality of Life (QoL), alleviate suffering; not curative.
• Multidisciplinary Team (MDT): Essential for comprehensive assessment & care planning.
  • Team: Surgeons, oncologists, palliative specialists, nurses, psycho-social support.
• Ethical Framework:
  • Autonomy: Respect patient's informed choices.
  • Beneficence: Act in patient's best interest.
  • Non-maleficence: "Primum non nocere"; avoid undue harm.
  • Justice: Equitable resource allocation.
• Communication & Shared Decision-Making:
  • Open, honest dialogue: prognosis, treatment goals, risks/benefits.
• Key Assessments:
  • Performance Status (e.g., ECOG, Karnofsky Performance Scale - KPS).
  • Symptom burden (e.g., pain, obstruction).
  • Patient/family values, preferences, and goals of care.

⭐ The "surprise question" ("Would I be surprised if this patient died in the next year?") is a simple tool to help identify patients who may benefit from palliative care discussions.

High‑Yield Points - ⚡ Biggest Takeaways

• Primary aim: Symptom palliation & improved Quality of Life (QoL), not curative intent.
• Key indications: Malignant obstruction (e.g., stenting, bypass), uncontrolled bleeding, severe pain.
• Fungating/infected tumors: Palliative resection or debridement for hygiene & comfort.
• Pathological fracture stabilization: For pain relief & maintaining function.
• Patient selection: Based on life expectancy (often >3 months for major procedures) & ECOG/Karnofsky status.
• Prefer minimally invasive surgery (MIS) for lower morbidity & faster recovery.
• Multidisciplinary team (MDT) input is vital for appropriate intervention.
