Peri-operative approach

Elective surgery should be jointly planned with hepatology, anaesthesia and surgery, with explicit consideration of whether the indication can be deferred while reversible decompensation is treated; decompensated cirrhosis warrants hospital admission or immediate specialist hepatology/gastroenterology input.

Pre-operative assessment and optimisation

  • Define cirrhosis stage and current decompensation by assessing for jaundice, ascites, hepatic encephalopathy and previous/current variceal bleeding.
  • Take a focused history covering liver-disease aetiology and risk factors, symptom trajectory, comorbidities, medication and alcohol use, functional impact, and previous cirrhotic complications.
  • Examine specifically for malnutrition, muscle wasting/frailty, chronic liver disease stigmata, jaundice, peripheral oedema, ascites and encephalopathy.
  • Obtain liver blood tests and tests needed to assess underlying cause and severity of liver disease; assess renal function and electrolytes because AKI risk is increased by hypovolaemia, diuretics, nephrotoxins, gastrointestinal bleeding and infection.
  • Use albumin and MELD as markers of advanced disease when discussing operative risk; in cirrhosis, albumin below 35 g/L or MELD of at least 10 identified groups at higher risk of hepatic decompensation and fatal adverse events in the cited evidence base.
  • Screen actively for infection, including spontaneous bacterial peritonitis in a patient with ascites, because cirrhosis confers immunosuppression and infection can precipitate gastrointestinal bleeding, AKI and shock.
  • Identify and treat encephalopathy precipitants before elective surgery, particularly constipation, dehydration, electrolyte disturbance, infection, gastrointestinal bleeding and precipitating drugs.
  • Assess nutritional risk and arrange dietitian input where indicated, as malnutrition, sarcopenia and frailty are common cirrhosis complications.
  • Review all medicines in relation to liver function and avoid or minimise drugs likely to precipitate encephalopathy, including opioids, benzodiazepines and inappropriate diuretic exposure.
  • Assess thrombocytopenia and haemostatic risk in conjunction with the procedural bleeding risk, but do not use eltrombopag solely to prepare thrombocytopenic chronic liver disease patients for an invasive procedure because it is not indicated for that purpose and has been associated with portal venous thrombosis.
  • Document both bleeding and thrombosis risk, since thrombotic events, particularly portal-vein thrombosis, occurred in patients with chronic liver disease receiving eltrombopag before invasive procedures.

Risk stratification and decision-making

  • Classify the patient clinically as compensated or decompensated: decompensated disease is characterised by potentially life-threatening jaundice, ascites, hepatic encephalopathy and/or variceal bleeding.
  • Regard large-volume or refractory ascites as a marker of severe hepatic impairment and high risk of complications including spontaneous bacterial peritonitis, hyponatraemia and hepatorenal syndrome.
  • Discuss the incremental risk associated with poor synthetic reserve, renal dysfunction, active infection, encephalopathy, ascites, prior bleeding, malnutrition/frailty and the magnitude/urgency of surgery in a multidisciplinary setting.
  • For non-urgent procedures, defer surgery where possible until infection, hypovolaemia, electrolyte disturbance, encephalopathy and ascites are stabilised.

Intra-operative management

  • Maintain effective circulating volume and renal perfusion while avoiding fluid imbalance, because cirrhosis predisposes to AKI and hepatorenal syndrome.
  • Use anaesthetic and analgesic drugs cautiously, minimising factors that can worsen encephalopathy; surgery itself and opioids or benzodiazepines are recognised precipitants.
  • If sevoflurane is used, inform anaesthesia of relevant concomitant medication: calcium-channel blockers may increase hypotension/negative inotropy, beta-blockers may augment negative inotropic and chronotropic effects, and exogenous adrenaline/noradrenaline requires caution because of ventricular-arrhythmia risk.
  • Ensure meticulous infection prevention and prompt treatment of suspected infection, given the heightened susceptibility to serious infection and sepsis in cirrhosis.
  • Anticipate bleeding from portal hypertension or coagulopathy while also maintaining awareness that cirrhosis does not eliminate thrombotic risk.

Post-operative management

  • Monitor closely for hepatic decompensation, including new/worsening jaundice, ascites, encephalopathy and variceal or other gastrointestinal bleeding.
  • Perform regular clinical and biochemical surveillance for AKI, volume disturbance and electrolyte abnormality, and promptly address dehydration, bleeding, infection and nephrotoxic or excessive diuretic exposure.
  • Use opioid-sparing analgesia where feasible and avoid benzodiazepines unless essential, while monitoring cognition and bowel function because surgery, opioids, benzodiazepines and constipation can precipitate encephalopathy.
  • Investigate fever, abdominal pain or increasing ascites urgently for infection, including spontaneous bacterial peritonitis, and treat suspected infection promptly.
  • Re-establish nutrition early and involve dietetics for malnutrition, sarcopenia or frailty.
  • Continue multidisciplinary hepatology follow-up after discharge and ensure ongoing monitoring and treatment of the underlying liver disease and cirrhotic complications.
