超声在急性阑尾炎临床诊断和分型中的临床意义

目的 探讨超声在急性阑尾炎诊断及病理分型中的作用和意义.方法 回顾2010年4月～2011 年11月急诊就诊的急腹症患者168例,均进行手术治疗,比较术前超声检查诊断结果 与术后病理检查结果 的差异.结果 单纯性阑尾炎超声诊断准确率为97.1%,化脓性阑尾炎准确率为95.2%,坏疽性阑尾炎准确率为100%,超声总的诊断准确率为97.1%;阑尾炎组的阑尾超声结果 显示其阑尾直径、长度、管壁厚度均高于非阑尾炎急腹症患者(P＜0.01).结论 超声检查对急性阑尾炎诊断准确率很高,具有重要的诊断价值,应作为首选辅助诊断方法.

Clinical Significance of Ultrasound in Acute Appendicitis Diagnosis and Pathological Typing

Objective To study the significance of ultrasound in acute appendicitis diagnosis and pathological typing.Methods A retrospective review of 168 cases of emergency patients with acute abdomen with operation in the years April 2010 ～ November 2011 was done with comparison between preoperative ultrasonography diagnosis results and postoperative pathological examination results.Results Simple appendicitis ultrasound diagnostic accuracy rate was 97.1%,suppurative appendicitis accuracy rate was 95.2%,gangrenous appendicitis ultrasound accuracy rate was 100%,the overall diagnostic accuracy rate was 97.1%.Appendiceal ultrasonography of appendicitis group shows that the appendiceal diameter, length,wall thickness were higher than that of nonacute-appendicitis patients（P 〈 0.01）.Conclusion Ultrasonography on acute appendicitis diagnosis accuracy rate is very high,which has important diagnostic value,and should be preferred as auxiliary diagnostic method.
