Surgery in the patient with liver disease

Area of Science:

• Hepatology
• Surgical Risk Assessment
• Internal Medicine

Background:

• Increasing prevalence of liver disease and improved patient survival necessitate careful preoperative evaluation.
• Hepatic dysfunction significantly increases perioperative morbidity and mortality due to the liver's vital physiological roles.
• Precise surgical risks for specific liver diseases remain poorly understood, correlating with the degree of hepatic impairment.

Purpose of the Study:

• To highlight the increased risks for patients with liver disease undergoing surgery.
• To emphasize the need for thorough preoperative assessment in this patient population.
• To identify key factors for risk reduction in surgical patients with liver disease.

Main Methods:

• Review of existing literature on liver disease and surgical outcomes.
• Analysis of physiological impacts of hepatic dysfunction on surgical risk.
• Identification of critical preoperative parameters for patient management.

Main Results:

• Hepatic dysfunction is a major risk factor for perioperative complications and mortality.
• The severity of liver impairment directly correlates with increased surgical risks.
• Specific liver diseases present unique, though often poorly defined, surgical challenges.

Conclusions:

• Optimal preoperative management of coagulation, volume status, renal function, electrolytes, cardiovascular health, and nutrition is crucial.
• Proactive identification and management of preexisting conditions can mitigate surgical risks.
• Improved preoperative assessment strategies are essential to decrease mortality in patients with liver disease undergoing surgery.
