高低频超声联合检查在不典型阑尾炎诊断中的应用价值

Application value of high frequency ultrasound combined with low frequency ultrasound in the di-agnosis of atypical appendicitis

目的：探讨高低频超声联合检查在不典型阑尾炎患者诊断中的应用价值。方法选取山东省胸科医院超声科2010年1月至2013年10月期间，临床症状体征不典型的50例急性阑尾炎患者，术后进行声像图回顾性分析，通过对手术病理及随访结果的比较，做出临床评价，全部患者均经术后病理证实。结果50例患者超声提示阑尾炎47例，符合率为94%。经病理证实单纯性病变6例，化脓性炎症病变25例，阑尾周围出现脓肿10例，坏疽者6例。其中高频超声显示阑尾34例，符合率为68%；腹部常规超声显示阑尾22例，符合率为44%；高低频超声相结合显示阑尾47例，符合率为94%。结论对疑似阑尾炎，但临床症状体征不典型的患者，高低频超声联合检查能更为清楚地显示阑尾形态改变程度，具有较高的诊断符合率。

Objective To investigate the application value of high frequency ultrasound com-bined with low frequency ultrasound examination on the diagnosis of atypical appendicitis. Methods Fifty cases of acute appendicitis without typical clinical signs and symptoms were selected in department of ultrasound of Shandong provincial chest hospital between January 2010 and October 2013,they were analyzed retrospectively by ultrasonography after operation. Clinical evaluation was made through the comparison of the pathological and follow-up results of the operation. All cases were confirmed by postop-erative pathology. Results Forty-seven cases were diagnosed by ultrasound,the coincidence rate was 94% . Pathologically confirmed 6 cases of simple lesions,25 cases of suppurative inflammation,abscess in 10 cases of appendiceal,6 cases of gangrene. The high frequency ultrasound showed the appendix in 34 cases,the coincidence rate was 68% ;abdominal ultrasound showed the appendix in 22 cases,the co-incidence rate was 44% ;high frequency ultrasonography combined with low frequency ultrasound exami-nation showed the appendix in 47 cases,the coincidence rate was 94% . Conclusions For suspected patients with appendicitis,but without typical clinical signs and symptoms,high and low frequency ultra-sound examination can more clearly show the morphological changes of the appendix,the diagnostic ac-cordance rate is high.
