Title: Perioperative Management of Liver Transplant Patients

Perioperative Management of Liver Transplant
  • January 22, 2007
  • Geoffrey Schultz, MD

Topic Objectives
  • 1. Overview of indications selection for liver
  • 2. Identification treatment of complications
    associated with liver disease in the preoperative
  • 3. Identification treatment of complications
    following orthotopic liver transplantation.
  • 4. Induction of immunosuppressive pharmacotherapy
    following transplantation.
  • 5. Diagnosis treatment of graft rejection.

Orthotopic Liver Transplantation
  • 1st orthotopic liver transplantation 1963.
  • Approximately 5,000 orthotopic liver
    transplantations annually for 17,000 in need.

Indications for Liver Transplantation in
Adults Etiologies of End-Stage Liver Disease
  • 1. Fulminant Hepatic Failure
  • 2. Alcoholic Liver Disease
  • 3. Chronic Hepatitis C
  • 4. Chronic Hepatitis B
  • 5. Non-alcoholic steatohepatitis
  • 6. Autoimmune Hepatitis
  • 7. Primary Biliary Cirrhosis
  • 8. Primary Sclerosing Cholangitis
  • 9. Hepatic tumors
  • 10. Metabolic and genetic disorders

Indications for Liver Transplantation in Adults
  • Presence of irreversible liver disease and a life
    expectancy of less than 12 months with no
    effective medical or surgical alternatives to
  • Chronic liver disease that has progressed to the
    point of significant interference with the
    patient's ability to work or with his/her quality
    of life
  • Progression of liver disease that will
    predictably result in mortality exceeding that of
    transplantation (85 one-year patient survival
    and 70 five-year survival)

Manifestations of End-Stage Liver Disease
  • Progressive jaundice
  • Intractable ascites
  • Spontaneous bacterial peritonitis
  • Hepatorenal Syndrome
  • Encephalopathy
  • Variceal bleeding
  • Intractable pruritus
  • Chronic fatigue (such as resulting in loss of
    gainful employment)
  • Bleeding diathesis or coagulopathy

Selection Criteria for Organ Allocation
  • United Network for Organ Sharing (UNOS) governing
    body for organ allocation utilizes MELD score.
  • Model for End Stage Liver Disease (MELD) Score
  • 0.957 x loge (creatinine) 0.378 x loge
    (bilirubin mg/dL) 1.12 x loge (INR) 0.643 x
  • Range from 10 to 40
  • Special considerations, amendments for HCC, renal

Preoperative management of complications
associated with hepatic failure decompensated
  • Hepatic Encephalopathy
  • Cerebral Edema
  • Acute Renal Failure
  • Infection Sepsis
  • Metabolic Derangements
  • Malnutrition
  • Coagulopathy
  • Portal Hypertension

Hepatic Encephalopathy
  • Etiology Attributed to increased serum ammonia
    levels secondary to metabolism of nitrogenous
    substances in the gut.
  • Symptoms Range from euphoria to coma.
  • Treatment lactulose, decreased intake of
    nitrogen containing compounds, oral neomycin.

Cerebral Edema
  • Etiology Unknown
  • Swelling of brain results in increased ICP
  • Invasive monitoring with goal of ICP lt 20 mmHg
    CPP gt 50 mmHg.
  • Treatment Anxiolysis, HOB elevation,
    hyperventilation, avoidance of overhydration,
    mannitol diuresis, HD if compromised renal

Acute Renal Failure
  • Etiology Toxin induced, Derangements in systemic
    intrarenal hemodynamics.
  • Treatment Prevention of hypotension, treatment
    of infection, avoidance of nephrotoxic agents.
  • Once established, renal failure in this setting
    is often irreversible. Early utilization of renal
    replacement therapy is indicated.

Infection Sepsis
  • Etiology Immunologic derangements including
    complement deficiency, reduced opsonins, WBC
  • Treatment Frequent cultures, including ascites.
    Broad spectrum antibiotics, including

Metabolic Derangements
  • 1. Hypokalemia
  • Increased sympathetic tone promotes cellular
    uptake of K. Decreased serum K promotes
    production of ammonia by the kidney.
  • 2. Hyponatremia
  • 3. Hypoglycemia
  • Secondary to decreased hepatic glycogen stores
    decreased gluconeogenesis.

  • Etiology Compromised synthetic function,
    deficiency of coagulation factors, platelet
  • Contribute to GI bleeding in conjunction with
    portal hypertension.
  • Treatment Prevention with H2 blockers, PPI.
    Judicious use of Factor VIIa FFP.

Post-operative complications management of
liver transplant patients
  • Right pleural effusion
  • May affect ventilation, necessitating drainage.
  • Hepatic edema secondary to aggressive
    resuscitation increased intravascular volume.
  • Goal CVP 6-10. Minimize increased hepatic vein
    pressures, sinusoidal congestion that impair
    graft perfusion exacerbate reperfusion injury.

Post-operative complications management of
liver transplant patients
  • Renal failure
  • Elevation of creatinine BUN observed in nearly
    all transplant patients secondary to ATN,
    hepatorenal syndrome. Usually self-limiting. May
    necessitate therapy with loop diuretics, renal
    replacement therapy.

Post-operative complications management of
liver transplant patients
  • Electrolyte Derangements
  • Recovering graft increases demand for magnesium
  • Transfusion of citrate rich blood products
    results in decreased serum magnesium calcium.
  • Rapid correction of chronic hyponatremia with
    isotonic solution can have severe neurological
    consequence. Judicious use of hypotonic solutions
    with goal of serum Na 125-130 advised.

Post-operative complications management of
liver transplant patients
  • Thrombocytopenia
  • Preoperative portal hypertension results in
    splenomegaly platelet sequestration. Generally
    improves as graft recovers. May necessitate
    replacement if bleeding is encountered or
    invasive procedures are planned. Splenectomy is
    rarely indicated.
  • Platelet dysfunction secondary to renal hepatic
    failure may be improved acutely with DDAVP.

Post-operative complications management of
liver transplant patients
  • Biliary leak
  • RUQ pain, fever, persistent elevation of
    bilirubin, liver enzymes. Biloma on CT. Treated
    with endoscopic stent, percutaneous drainage.
    Possible surgical revision if duct is ischemic.
  • Hepatic artery thrombosis
  • Persistent elevation or increasing liver enzymes,
    poor graft function. Diagnosed with U/S, CT
    angiography, MRA. Treated with immediate

Induction of Immunosuppression
  • Triple therapy
  • Calcineurin inhibitor (tacrolimus, cyclosporine),
    anti-proliferative agent (mycophenolate),
    corticosteroid taper.
  • Initiated immediately following transplantation.
  • Levels followed daily in immediate post-operative
    period with decreasing frequency once
    stabilized in desired range.
  • Agents vary according to etiology of liver
  • Thymoglobulin Hb Ig utilized in hepatitis
    patients along with entecavir prograf to limit
    viral replication to avoid coritocsteroid

Allograft rejection
  • Hyperacute rejection
  • Secondary to preformed Ab to graft antigen.
    Extremely rare. Necessitates retransplantation.
  • Acute Cellular Rejection
  • 70 of patients 5 to 14 days following
  • Heralded by fever, jaundice, elevation of liver
  • Diagnosed by liver biopsy. Demonstrates
    endothelialitis non-suppurative cholangitis.
