Core Tip
Core Tip: This study demonstrates that combining preoperative shear wave elastography with the fibrosis-4 index significantly improves the predictive accuracy of significant liver fibrosis after hepatectomy in patients with cirrhosis. The combined model achieved an area under the curve of 0.979, superior to either index alone. This non-invasive and easy-to-implement strategy facilitates more accurate preoperative risk stratification and individualized surgical planning, potentially improving patient outcomes.
