Hepatobiliary Diseases

This multi-center, prospective observational study aims to develop and validate an interpretable prediction model for Myocardial Injury After Noncardiac Surgery (MINS) in patients undergoing major hepatobiliary surgery. The study adopts a nested modeling strategy, starting with baseline risk factors (e.g., RCRI) and stepwise incorporating hepatic inflow occlusion strategies (specifically comparing SPVO vs. Pringle maneuver) and routine intraoperative biomarkers. The model's performance will be evaluated using AUC, Net Reclassification Improvement (NRI), and Decision Curve Analysis (DCA), followed by interpretability analysis using SHAP values and external validation in an independent cohort.

The goal of this observational study is to evaluate clinical and oncologic outcomes in adult patients undergoing liver and/or biliary resection for benign and malignant diseases. This study evaluates postoperative morbidity and mortality within 90 days after surgery, as well as overall survival and disease-free survival in patients with malignant disease. Participants will: * undergo standard surgical and perioperative management according to routine clinical practice * have clinical, surgical, and follow-up data collected from institutional medical records * be followed for postoperative outcomes and long-term oncologic outcomes up to 5 years
