Hyperthermic intraperitonal chemotherapy surgery (HIPEC) and cytoreductive surgery is a combined procedure utilized to treat peritoneal surface cancers.[1] These cancers include secondary peritoneal carcinomatosis, pseudomyxoma peritonei and primary peritoneal tumors.[1][2]  Cytoreductive surgery involves debulking the majority of tumors until the remainder are small enough to ensure adequate efficacy with HIPEC.

HIPEC involves infusing heated cytotoxic chemotherapeutic drugs directly into the surgical site in order to effectively penetrate involved cancer while limiting exposure to normal tissue and decrease systemic uptake.[1][3][4] This may be performed in a closed abdomen via perfusion circuit or an open abdomen +/- cavity expanders.[5]  An open abdomen technique may reduce increased intraabdominal pressures and prevent reuse of the cytotoxic solution.  However, the closed abdomen technique reduces risk of exposure of the medications to the OR staff.

Important perioperative considerations include temperature management, cardiovascular management, intra-abdominal pressures, metabolic derangements (depending on carrier solution of chemotherapeutic agent), potential toxicities (see table below), coagulopathy, fluid/renal management and pain management.[1][3]

Intraoperatively, OR staff may be exposed to cytotoxic agents due to high concentrations of chemotherapeutic medications, long case duration,  and smoke and or mechanical exposure. Pregnant or those actively planning for pregnancy, those with a history of congenital malformations or abortions should carefully consider participation in HIPEC cases. Safety precautions including high-power filtration masks, eye protection, gloves, and standard universal precautions should always be heeded.[6]

Monitor creatinine and GFR

Abnormal electrolytes

Endocrine
Other Patients may need nutrition optimization prior to surgery

Patients can benefit from active prehabilitation prior to surgery

Labs and studies

  • CMP (particularly renal function and electrolytes)
  • CBC (identify and correct anemia)
  • Consider pre-albumin to evaluate nutrition status

Operating room setup

  • Fluid warmer
  • Arterial line setup
  • ± Central line
  • ± Cardiac output monitor (i.e. Flowtrack)
  • NG tube
  • Vasopressor drips
  • Blood products

Patient preparation and premedication

  • Preoperative nutrition consult
  • Preoperative prehabilitation plan

Regional and neuraxial techniques

  • Epidural or paravertebral blocks (if epidural is contraindicated)

Intraoperative management

Monitoring and access

  • Multiple large-bore PIVs (for active fluid resuscitation)
  • ± Rapid infusion catheter
  • Arterial line
  • ± Central venous catheter

Induction and airway management

  • General anesthesia with ETT

Surgical Timeout Communication

Operative goals are crucial to delineate with the surgical team prior to incision. Key discussion points include:

  1. Patient Risk Factors
  2. DVT prophylaxis
  3. Fluid Goals
  4. Confirm urine output goals for cisplatin only
  5. Body Temperature Management plus additional monitors (esophageal, nasopharyngeal, bladder, axillary, etc)
  6. Type of chemotherapy agent used, including dilution solution and its implications on electrolytes
  7. Consideration for further renal protection therapy
  8. Trigger for blood transfusion
  9. Preoperative antibiotic choice

Positioning

  • Supine

Maintenance and surgical considerations

Cytoreductive Phase
  • Fluid resuscitation to maintain euvolemia: consider to utilize arterial line and cardiac output monitoring to guide fluid resuscitation and avoid over-resuscitation
  • Check ABG and base deficit q1hour
  • Check coagulation status q4 hours
  • Resuscitate with lactated ringers or plasma-lyte (Avoid normal saline)
  • Consider albumin administration for intravascular fluids
  • Maintain normothermia to mild hypothermia (target temp 35-36.5 °C)
  • Monitor urine output and evaluate volume status. If UOP less than 0.5 mL/kg/hr - Consider vasopressin or norepinephrine to maintain MAP if patient is hypotensive but not hypovolemic
  • Obtain pre-HIPEC chemistries (Na+, K+, Mg2+, Ca2+)[9]
HIPEC Phase
  • Maintain good muscle relaxation
  • Intra-abdominal pressure may be elevated up to 26 mm Hg
    • Maintain abdominal perfusion pressure of >60 (MAP – IAP)
  • Manage ventilation to maintain normocarbia and normoxia
  • Avoid hypervolemia during high volume resuscitation
  • Check ABG and base deficit q30min to q1hour
    • Treat hyperglycemia (>200) with insulin drip
    • Treat hyponatremia
      • Diuretics for hypervolemia
      • Volume resuscitate for hypovolemia; consider hypertonic saline if Na<130
  • Check electrolytes (Na+, K+, Mg2+, Ca2+) during HIPEC phase
  • Continue to check coagulation factors q4 hour
  • Goal intraperitoneal tissue temperature: 41-43 °C
  • Watch for core temperature >39.5 °C
    • Consider passive cooling vs active cooling with ice
    • Consider cooling intraperitoneal fluids
  • Cisplatin Perfusion ONLY:
    • sodium thiosulfate bolus at start of chemoperfusion
    • Sodium thiosulfate drip starts immediately after bolus over 12 hrs
    • Crystalloid (avoid NS) to maintain urine output > 100mL/hr through the end of case and into PACU / ICU

Emergence

  • After fascia is closed, check twitches and reverse paralysis
  • Plan for extubation if hemodynamically stable, normothermic and normoxic

Postoperative management

Disposition

  • Admit to ICU (consider discussion with ICU team and surgeon beforehand)
  • UOP Goals: UOP 100 mL/hr (for Cisplatin only)
  • May require pressors due to prolonged vasoplegia postoperatively
  • Continue Sodium thiosulfate drip over 12 hours from start of perfusion (for cisplatin only)

Pain management

  • PCEA
  • IV acetaminophen
  • ketoralac (if perfusion with MMC, no pre-existing kidney disease)

Potential complications

  • variable
  • surgical complications: anastomotic leakage, bleeding, infection;
  • medical / chemo-related: myelosuppression (MMC),
  • nephrotoxicity (Cisplatin)

Procedure variants

Open Abdominal

Perfusion

Closed Abdominal
