[Perioperative risk among patients with cirrhosis]

Area of Science:

• Hepatology
• Surgical Risk Assessment
• Liver Disease Management

Context:

• Liver cirrhosis significantly impacts surgical outcomes, with approximately 10% of patients requiring surgical intervention.
• Assessing surgical risk in patients with compromised liver function is critical for patient management.
• Traditional prognostic scores like Child-Pugh have limitations, leading to the development of the Model for End Stage Liver Disease (MELD) score.

Purpose:

• To review the surgical risks associated with liver damage and surgical procedures in cirrhotic patients.
• To evaluate the prognostic significance of liver function impairment in surgical outcomes.
• To discuss the utility and limitations of Child-Pugh and MELD scores in predicting surgical risk.

Summary:

• The degree of liver functional impairment is the primary prognostic factor, evaluated by Child-Pugh and MELD scores.
• Surgical risk varies by procedure type, with cardiac surgery posing the highest risk and extra-thoracic/abdominal procedures the lowest.
• Mortality rates for abdominal surgery range widely (11-76%), with biliary surgery showing frequent complications; laparoscopic approaches may reduce risk.
• In liver resective surgery, risk is determined by liver function and excision size. High creatinine, cardiac failure, and emergency surgery are independent risk factors.

Impact:

• Highlights the importance of MELD score in predicting surgical risk, while emphasizing the need for individualized patient assessment.
• Informs clinical decision-making for surgeons and hepatologists managing cirrhotic patients requiring surgery.
• Underscores the necessity of careful surgical planning to mitigate risks in this vulnerable patient population.
