The high negative exploration rate in patients with suspected acute appendicitis is the main compelling reason to improve the accuracy in managing patients with acute abdominal pain. In this article, data from a prospective study on a group of patients undergoing an acute appendectomy were used to devise a scoring system for the purpose of differentiating between the patients with an acute appendicitis and those found to have a normal appendix at operation. The results show that by using the scoring system described, 30% of the unnecessary appendectomies could have been avoided. These findings show the potential value of this method. The results of the prospective study were compared with the results of a retrospective study on the same group of patients demonstrating a significant difference and hence the unreliability of retrospective studies.
疑似急性阑尾炎患者的高阴性探查率是提高急性腹痛患者管理准确性的主要迫切原因。在本文中，一组接受急性阑尾切除术患者的前瞻性研究数据被用于设计一个评分系统，目的是区分患有急性阑尾炎的患者和手术中发现阑尾正常的患者。结果显示，通过使用所描述的评分系统，30%的不必要阑尾切除术本可避免。这些发现表明了该方法的潜在价值。将该前瞻性研究的结果与对同一组患者的回顾性研究结果进行比较，显示出显著差异，因此回顾性研究不可靠。
