High-resolution real-time ultrasound (US) with a 5 MHz transducer has proved to be an important method in the diagnosis of acute appendicitis. In a prospective study we examined 2074 unselected patients with suspected appendicitis to assess the diagnostic and epidemiological value of US. According to the clinical diagnosis females aged 10 to 30 represented the majority of suspected cases. Appendicitis was most often proved in male patients aged 15-30 years. The prevalence of acute appendicitis in childhood is lower (7%) than in elderly patients (33%). US enables the diagnosis of acute appendicitis with a sensitivity of 91%, a specificity of 98% and an overall accuracy of 97%. For differential diagnosis US demonstrates other diseases that mimic acute appendicitis. Thus it is possible to reduce the negative appendectomy rate particularly in children by revealing mesenteric lymphadenitis or terminal ileitis and in young women by directing attention to gynecological diseases.
使用5兆赫换能器的高分辨率实时超声（US）已被证明是诊断急性阑尾炎的一种重要方法。在一项前瞻性研究中，我们检查了2074例未经挑选的疑似阑尾炎患者，以评估超声的诊断和流行病学价值。根据临床诊断，10至30岁的女性占疑似病例的大多数。阑尾炎最常出现在15 - 30岁的男性患者中。儿童急性阑尾炎的患病率（7%）低于老年患者（33%）。超声诊断急性阑尾炎的敏感性为91%，特异性为98%，总体准确率为97%。对于鉴别诊断，超声可显示其他类似急性阑尾炎的疾病。因此，通过发现肠系膜淋巴结炎或末端回肠炎，特别是在儿童中，以及通过关注妇科疾病，特别是在年轻女性中，有可能降低阴性阑尾切除率。
