Learning objectives
- Define orthotopic liver transplantation
- Understand the considerations of patients with a previous liver transplant
- Manage patients with a liver transplant liver undergoing nontransplant surgery
Definition and mechanisms
- Liver transplantation is a treatment option for end-stage liver disease (ESLD) and acute liver failure
- Orthotopic liver transplantation is the most common technique and involves the substitution of a diseased native liver with a normal liver (or part of one) taken from a deceased or liver donor in the same anatomic position as the original liver
- Recipients may present for nontransplant surgery later in life
Considerations
- The majority of recipients are 30-60 years old and in good health
- Cardiopulmonary effects of ESLD reverse shortly after transplantation
- Most patients have normal liver function unless there is rejection, sepsis, or recurrence of the original disease
- High incidence of hypertension after liver transplantation
- Immunosuppression increases susceptibility to infection and other common side effects
- Corticosteroids: Hypertension, hypokalemia, hyperglycemia, adrenal suppression
- Tacrolimus: Hypertension, renal dysfunction, electrolyte abnormalities, hyperglycemia
- Cyclosporine: Nephrotoxicity and hyperkalemia, hepatotoxicity, neurotoxicity, hypertension
- Azathioprine: Bone marrow suppression
Management
Keep in mind
- Increasing numbers of patients have a successful liver transplant and may require nontransplant surgery later in life
- Careful preoperative assessment is essential, especially for liver and kidney function
- The goal of perioperative management is to avoid any factors that might compromise hepatic and renal function and to minimize the infection risk with antibiotic prophylaxis and careful aseptic techniques
