低频与高频探头超声用于诊断急性阑尾炎的临床效果比较

Comparison on Effects of Low-Frequency Ultrasound and High-Frequency Ultrasound for Diagnosis of Acute Appendicitis

目的比较低频与高频探头超声用于诊断急性阑尾炎的临床效果。方法选取我院于2012年3月至2014年3月收治的118例急性阑尾炎患者,回顾分析其病理结果和超声检查结果,对低频与高频探头超声用于诊断急性阑尾炎的临床效果进行分析比较。结果在所有急性阑尾炎病例中,低频探头超声的检出率为55.08%,高频探头超声的检出率为87.29%,差异具有统计学意义(P<0.05);在单纯性阑尾炎与坏疽性及化脓性阑尾炎的诊断中,高频探头超声的检出率显著高于低频探头超声的检出率,差异具有统计学意义(P<0.05);低频探头超声、高频探头超声对阑尾周围脓肿的检出率均为100.00%。结论在急性阑尾炎的诊断中,高频探头超声的检出率明显高于低频探头超声,两者联合诊断其检出率将大大提高,值得临床推广与应用。

Objective To compare the clinical effects of low-frequency ultrasound and high-frequency ultrasound for diagnosis of acute appendicitis. Methods 118 patients with acute appendicitis admitted to our hospital from March 2012 to March 2014 were selected in this study. The pathology results and ultrasound results were analyzed retrospectively, and the diagnostic results of low-frequency ultrasound and high-frequency ultrasound were compared. Results Among all cases of acute appendicitis, the detection rates of acute appendicitis of low-frequency ultrasound and high-frequency ultrasound were 55.08% and 87.29% respectively, with statistical difference（P 0.05）. The detection rates of simple appendicitis, and gangrenous/suppurative appendicitis of high-frequency ultrasound were significantly higher than those of low-frequency ultrasound, and the differences were statistically significant（P 0.05）. Both the detection rates of appendiceal abscess of low-frequency ultrasound and high-frequency ultrasound were 100.00%. Conclusions High-frequency ultrasound has higher detection rate of acute appendicitis compared with low-frequency ultrasound, but a combination of both will greatly improve the diagnosis rate and deserve clinical application.
