This study aimed to propose an appendicitis prognostic score (APS) for predicting surgical outcome and assessing the influence of surgical delay on postoperative complications. Methods: From 2013 to 2019 patients diagnosed with acute appendicitis requiring an emergent appendectomy were divided into training (2013-2018) and validation groups (2019). The APS was developed from preoperative characteristics related to a perforated appendicitis in the training group, then correlated with postoperative complications (surgical site infection, intra-abdominal abscess and ileus) and verified by the validation group. The effects of surgical delay on postoperative complications was evaluated between high and low APS subgroups. Results: APS criteria included age >45, body temperature >37.5°C, heart rate >95bpm, breathing rate >20/min, diastolic blood pressure <75mmHg, and abdominal pain duration 24-48h and >48h, with a maximum of 8 points. A high APS (≥4 points) was significantly associated with an increased complication rate in the validation group (p=0.016). Further analysis of the training group showed that patients with ≥4 points had a higher overall complication (21.85% vs. 11.27%, p=0.006) and surgical site infection rate (11.92% vs. 4.69%, p=0.011) if surgical delay exceeded 12 hours. Conclusion: The APS is a practical metric for predicting postoperative complications. It is recommended that patients with an APS score ≥4 undergo an appendectomy within 12 hours to avoid an increased risk of overall complications and surgical site infection. |
