One hundred consecutive patients admitted to the hospital with the prospective diagnosis of appendicitis were evaluated retrospectively to determine the effect of the use of modern diagnostic techniques upon the accuracy of preoperative diagnosis. Appendectomy was performed on 48 patients. In three of these patients, the diagnostic process was assisted by the use of radiologic or ultrasound techniques. Of the 52 patients who did not undergo appendectomy, 13 patients clearly avoided surgery or were steered towards an other appropriate operative procedure due to findings on ultrasound or barium enema. Ultrasound was particularly useful in differentiating the etiology of right lower quadrant pain in the childbearing aged female. This study demonstrates that the traditionally expected 15% normal appendix rate can be narrowed (6.25% in this group of patients) without increasing morbidity, with the use of sophisticated diagnostic techniques in the evaluation of selected patients who present diagnostic dilemmas.
对连续100例入院时初步诊断为阑尾炎的患者进行回顾性评估，以确定使用现代诊断技术对术前诊断准确性的影响。48例患者接受了阑尾切除术。其中3例患者在诊断过程中使用了放射学或超声技术辅助。在未接受阑尾切除术的52例患者中，13例患者由于超声或钡灌肠检查结果明确避免了手术或转向了其他合适的手术程序。超声在区分育龄期女性右下腹疼痛的病因方面特别有用。这项研究表明，在评估存在诊断难题的特定患者时，使用先进的诊断技术可以在不增加发病率的情况下，将传统预期的15%的正常阑尾率降低（该组患者中为6.25%）。
