title: Preoperative preparation of patients with advanced liver disease.
abstract: OBJECTIVE
  To review the characteristic features of patients with advanced liver disease that may lead to increased perioperative morbidity and mortality rates.
  
  
  METHODS
  Literature review.
  
  
  RESULTS
  Patients with end-stage liver disease are at high risk of major complications and death following surgery. The most common complications are secondary to acute liver failure and include severe coagulopathy, encephalopathy, adult respiratory distress syndrome, acute renal failure, and sepsis. The degree of malnutrition, control of ascites, level of encephalopathy, prothrombin time, concentration of serum albumin, and concentration of serum bilirubin predict the risk of complications and death following surgery. Other determinants of adverse outcome include emergency surgery, advanced age, and cardiovascular disease. Portal hypertension is a prominent feature of advanced liver disease, and it predisposes the patient to variceal hemorrhage, hepatorenal syndrome, hepatopulmonary syndrome, and uncontrolled ascites. Portal hypertension can be ameliorated by percutaneous or surgical portasystemic shunting procedures. If well-defined contraindications are not present, patients with advanced liver disease should be evaluated for orthotopic liver transplantation from a cadaver donor or possible living-related liver transplantation.
  
  
  CONCLUSIONS
  Optimal preparation, which addresses the common features of advanced liver disease, may decrease the risk of complications or death following surgery. Preparation should include correcting coagulopathy, minimizing preexisting encephalopathy, preventing sepsis, and optimizing renal function.
