Core Tip	Clinically relevant biliary events within 30 days after laparoscopic cholecystectomy, such as retained common bile duct (CBD) stones, bile leak, cholangitis, and biliary pancreatitis, may necessitate endoscopic retrograde cholangiopancreatography (ERCP), drainage, or unplanned readmission. In this single-center retrospective cohort of 287 patients, 29 patients (10.1%) experienced the primary outcome. A parsimonious preoperative nomogram based on total bilirubin and a height-normalized CBD/height index showed robust discrimination in the original split-sample analysis, supportive bootstrap-based internal validation, and stable performance in a sensitivity analysis excluding patients who underwent preoperative ERCP.
