高频超声检查在小儿急性阑尾炎、急性肠系膜淋巴结炎临床诊断中的准确性研究

Study on the Accuracy of High-frequency Ultrasonography in the Clinical Diagnosis of Acute Appendicitis and Acute Mesenteric Lymphadenitis in Children

目的分析高频超声检查在小儿急性阑尾炎、急性肠系膜淋巴结炎临床诊断中的准确性研究。方法选取2019年2月-2021年2月本院收治的腹痛患者103例。以临床诊断结果为参考,统计高频超声对小儿急性阑尾炎、急性肠系膜淋巴结炎诊断结果,计算高频超声诊断疾病的敏感性、特异性、阳性预测值及阴性预测值。结果101例腹痛患儿中,临床诊断结果显示有59例小儿急性阑尾炎,42例急性肠系膜淋巴结炎。高频超声检出57例小儿急性阑尾炎、40例急性肠系膜淋巴结炎,对小儿急性阑尾炎诊断准确性为96.61%,对急性肠系膜淋巴结炎诊断准确性为95.24%,与临床诊断结果比较差异无统计学意义(P>0.05)。高频超声检查对小儿急性阑尾炎敏感性为86.44%、特异性为92.86%,对急性肠系膜淋巴结炎敏感性为92.86%、特异性为89.83%。高频超声检查对小儿急性阑尾炎阳性预测值为94.44%、阴性预测值为82.97%,对急性肠系膜淋巴结炎阳性预测值为86.67%、阴性预测值为94.64%。结论小儿急性阑尾炎和急性肠系膜淋巴结炎在高频超声检查中均具有较高诊断准确性且临床指标诊断性较高,值得临床大力推广。

Objective To analyze the accuracy of high-frequency ultrasonography in the clinical diagnosis of acute appendicitis and acute mesenteric lymphadenitis in children.Methods 101 patients with abdominal pain admitted to our hospital from February 2019 to February 2021 were selected.The clinical indicators,high-frequency ultrasound diagnosis results,high-frequency ultrasound sensitivity and specificity of children with acute appendicitis and acute mesenteric lymphadenitis were compared.Results The number of right lower quadrant metastatic pain,nausea and vomiting,right lower quadrant pain and abdominal tension in children with acute appendicitis was more than that in patients with acute mesenteric lymphadenitis(P<0.05).Among 101 children with abdominal pain,histopathological results showed 59 cases of acute appendicitis and 42 cases of acute mesenteric lymphadenitis,and high-frequency ultrasound detected 51 cases of acute appendicitis and 39 cases of acute mesenteric lymphadenitis,with an accuracy of 89.11%(P<0.05).High-frequency ultrasonography has a sensitivity of 86.44%and a specificity of 92.86%for acute appendicitis in children,and a sensitivity of 92.86%and a specificity of 89.83%for acute mesenteric lymphadenitis.Conclusion High-frequency ultrasonography has high diagnostic accuracy and high diagnostic rate of clinical indicators in children with acute appendicitis and acute mesenteric lymphadenitis,which is worthy of clinical promotion.
