New risk score predicts mortality after major liver resection

A newly developed preoperative risk score accurately predicts 90-day mortality in patients undergoing major liver resection, identifying five key factors: age ≥ 65 years, type 2 diabetes, primary liver cancer diagnosis, an American Society of Anesthesiologists score of ≥ 3, and extended hemihepatectomy. The score categorizes patients into low, intermediate, and high risk, with respective mortality rates of 3.5%, 11.1%, and 29.7%. Validation in a larger cohort further confirms its effectiveness in clinical decision-making.
