急性阑尾炎B超诊断特点分析

B-ultrasound diagnosis characteristics of acute appendicitis

目的探讨急性阑尾炎的B超诊断特点。方法选取本院2009年12月～2010年12月收治的疑似急性阑尾炎患者89例。全部进行B超检查，对B超诊断特点进行回顾性总结分析。结果本组患者经病理检查急性阑尾炎阳性66例（其中单纯性阑尾炎患者32例，化脓性阑尾炎患者15例，坏疽性阑尾炎患者12例，阑尾周围脓肿患者7例），急性阑尾炎阴性23例；经B超检查急性阑尾炎阳性64例，急性阑尾炎阴性25例。B超检查急性阑尾炎检查率为71．91％，敏感度为92．42％，特异度为86．96％，准确度为91．01％。结论B超在急性阑尾炎的临床诊断上具有方便、快捷、特异性强、结果可靠的特点，可以更好的辅助医师进行临床诊断，早期确定治疗方案，为急性阑尾炎诊断、治疗提供了客观依据，值得临床推广使用。

Objective To explore B-ultrasound diagnosis characteristics of acute appendicitis. Methods 89 cases of suspected acute appendicitis were selected in our hospital from December 2009 to Decembe2010.All the patients were given B-ultrasound diagnosis,retrospectively analyzed B-ultrasound diagnosis characteristics. Results 66 cases checked by pathological examination were acute appendicitis positive（32 cases had simple appendicitis,15 cases had suppurative appendicitis,12 cases had gangrenous appendicitis,7 cases had appendiceal abscess）,aeute appendicitis negative had 23 eases;64 cases checked by B-ultrasound diagnosis were acute appendicitis positive,25 cases were acute appendicitis negative. B-ultrasound diagnosed acute appendicitis,the examination rate was 71.91%,sensitivity was 92.42%,specificity was 86.96%,accuracy was 91.01% . Conclusion B ultrasound in the clinical diagnosis of acute appendicitis is convenient,fast,specificity and reliable. It can better assist physicians for clinical diagnosis,it can provide an objective basis for acute appendicitis diagnosis in early identification.It＇s worthy of clinical promotion.
