The diagnostic accuracy and practical value of graded compression ultrasound was evaluated in 298 patients admitted for ultrasound examination because of having suspected appendicitis by surgeons. The result of the ultrasound was considered to be positive, if the inflamed appendix, larger, than 6.5 mm in outer diameter or an abscess was depicted. Of the 99 pathologically proven cases of acute appendicitis ultrasound was positive in 94, that is the sensitivity was 94.9%. The diagnostic accuracy and specificity were 96.3% and 97.9%. The predictive value of a positive test was 95.9%, and was 97.5% of a negative one. In the group of patients under 18 years (140 patients) sensitivity, specificity and diagnostic accuracy were 93.3%, 96.3% and 95% respectively. The use of ultrasound helped many patients to earlier operation and reduced considerably the negative laparotomy rate. The routine use of ultrasound in the diagnosis of appendicitis especially if the clinical presentation is equivocal, complements usefully the clinical signs and increases diagnostic accuracy.
对298例因外科医生怀疑患有阑尾炎而入院接受超声检查的患者，评估了分级加压超声的诊断准确性和实用价值。如果超声显示发炎的阑尾外径大于6.5毫米或有脓肿，则超声结果被认为是阳性。在99例经病理证实的急性阑尾炎病例中，超声检查阳性的有94例，即敏感性为94.9%。诊断准确性和特异性分别为96.3%和97.9%。阳性试验的预测值为95.9%，阴性试验的预测值为97.5%。在18岁以下的患者组（140例患者）中，敏感性、特异性和诊断准确性分别为93.3%、96.3%和95%。超声的使用帮助许多患者更早地接受了手术，并大大降低了阴性剖腹率。在阑尾炎诊断中常规使用超声，特别是在临床表现不明确的情况下，对临床体征有很好的补充作用，并提高了诊断准确性。
