Appendicitis is a frequently encountered surgical emergency which can be diagnosed by clinical and laboratory criteria. But there are some atypical cases that ultrasound can help to diagnose. From April the 9th 1992 to April the 11th 1993, we have examined by ultrasound 465 patients entered in our hospital for right lower quadrant pain. 190 patients have been diagnosed as appendicitis and operated (true positive = 124 cases, false negative = 54 cases and false positive = 12 cases). 275 patients have been diagnosed as negative and they are not operated (true = 273 cases, false positive = 2 cases). So in our study, the sensitivity is 70%, the specificity is 95% and the accuracy is 85%. Our scientific report has the objective to show the usefulness and the limits of ultrasound in the diagnosis of appendicitis.
阑尾炎是一种常见的外科急症，可通过临床和实验室标准进行诊断。但存在一些非典型病例，超声有助于诊断。从1992年4月9日至1993年4月11日，我们对因右下腹痛入院的465例患者进行了超声检查。190例患者被诊断为阑尾炎并接受了手术（真阳性 = 124例，假阴性 = 54例，假阳性 = 12例）。275例患者被诊断为阴性且未接受手术（真阴性 = 273例，假阳性 = 2例）。因此，在我们的研究中，敏感性为70%，特异性为95%，准确性为85%。我们的科学报告旨在展示超声在阑尾炎诊断中的作用和局限性。
