Core Tip
Core Tip: This study establishes quantitative ultrasound thresholds for differentiating simple and suppurative appendicitis and develops a combined predictive model with high diagnostic accuracy. By integrating appendiceal diameter, wall thickness, and blood-flow grade, the model significantly improves preoperative assessment and directly guides surgical approach selection, reducing conversion to open surgery and postoperative complications.
