高低频超声联合检查在不典型阑尾炎诊断中的应用价值

The value of low frequency ultrasound associated with high frequency ultrasound in the diagnosis of acute appendicitis atypical clinical manifestations

目的:探讨低高频超声联合检查在不典型阑尾炎诊断中的应用价值。方法:选择症状、体征不典型,术后病理证实为急性阑尾炎的腹痛待查患者73例,回顾性分析术前超声检查,结合其临床症状、体征、术中所见及病理分析不典型阑尾炎超声声像图直接及间接征象。结果:73例患者术前超声提示急性阑尾炎62例,诊断率为84.9%。对照组为门急诊低频超声诊断率仅为54.1%。低、高频探头的联合使用提示阑尾粗大显示率与低频超声相比有统计学意义(P<0.01)。结论:低高频结合超声检查能提高显示阑尾肿胀及周围结构的显示率,有助于不典型阑尾炎的临床诊断,可成为常规辅助物理诊断方法之一。

Objective：This study was designed to assess the value of low frequency uhrasound and high frequency ultrasound in the diagnosis of acute appendicitis atypical clinical manifestations. Methods：In all of 73 Acute appen- dicitis patients with atypical clinical symptoms and signs,but confirmed by pathology and appendectomy were exam- ined and diagnosed by ultrasonic images reviewed.Results：Sixty-two patients were diagnosed by ultrasound.The rates of diagnosis showed significant difference in statistics with low frequency and high frequency （54.1% vs 84.9%,P〈 0.01）. Conclusions：In many cases,the correct diagnosis of acute appendicits with atypical clinical manifestations can be observed by high frequency ultrasound and low frequency ultrasound.
