摘要
目的:探讨高频超声结合低频超声检查在临床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,临床诊断腹痛待查患者65例,分别使用3.5-4.0MHz普通腹部探头和7.0-10.0MHz高频探头做超声检查,经手术后病理证实为急性阑尾炎共65例,结合其临床特征分析非典型急性阑尾炎超声声像图表现.结果:65例患者超声提示急性阑尾炎54例,显示率为83.08%.高频超声肿大阑尾显示率与低频超声相比差异有统计学意义(83.08%vs61.53%,χ2=4.32,P<0.05).低频超声结合高频超声显示非典型阑尾炎有一些间接征象:阑尾粪石33例(61.11%),周围肠管扩张25例(46.29%),阑尾周围积液21例(38.88%),阑尾周围包块14例(25.92%),肠系膜淋巴结肿大10例(18.52%).结论:高频结合低频超声检查能提高肿大阑尾及周围结构显示率,可成为临床不典型急性阑尾炎首选辅助诊断方法.
AIM： To explore the value of high and low frequency ultrasound in the diagnosis of acute appendicitis with atypical clinical manifestations. METHODS： A total of 65 acute appendicitis pa- tients with atypical clinical symptoms and signs but confirmed by surgery and pathology were examined and diagnosed by high frequency （7.0-10.0 MHz） associated with low frequency （3.5-4.0 MHz） ultrasound. Their ultrasonic im- ages of acute appendicitis were reviewed retro- spectively. RESULTS： Fifty-four （83.08%） patients were di- agnosed by ultrasound. The rates of diagnosis by high frequency and low frequency ultrasound were significantly different （83.08% vs 61.53%, Z2 = 4.32, P 〈 0.05）. Some indirect evidences were achieved by ultrasonography： appendiceal feca- lith was observed in 33 （61.11%） patients, local adynamic ileus in 25 （46.29%） patients, periap- pendicular fluid in 21 （38.88%） patients and complex mass in 14 （25.92%） patients. Mesen- teric lymphadenectasis was found in 10 （18.52%） patients. CONCLUSION： In most cases, the correct diag- nosis of acute appendicitis with atypical clinical manifestations can be made by high frequency associated with low frequency ultrasound.
