A validated risk score predicts 90-day mortality after liver resection

A novel preoperative risk score predicts 90-day mortality after major liver resection, identifying five key risk factors: age ≥ 65 years, type 2 diabetes, a diagnosis of primary liver cancer, ASA ≥3, and extended hemihepatectomy. In a cohort of 513 patients, the 90-day mortality rate was 10.8%, with predicted rates of 3.5% for low risk, 11.1% for intermediate risk, and 29.7% for high risk patients. External validation confirmed the score’s reliability.
