高频超声诊断小儿急性阑尾炎及分型的体会

Value of H-frequency ultrasonography in the diagnosis and classification of appendicitis in children

目的探讨小儿阑尾炎的声像图特征及其分型的价值。方法对90例临床拟诊急性阑尾炎的患儿行高频超声检查,分析其声像图特征并进行分型,与手术及病理结果对照。结果 90例拟诊急性阑尾炎的患儿,超声诊断总体符合率为98.9%。声像图显示阑尾增粗,壁增厚,黏膜毛糙、回声中断或缺失。病理类型符合率分别为:急性单纯性阑尾炎91.3%,化脓性阑尾炎97.8%,坏疽性阑尾炎76.2%,阑尾脓肿100%。结论高频超声检查对小儿阑尾炎的诊断及分型具有重要价值,能够较准确的估测炎症改变的程度,有利于临床医生选择合理的治疗方法。

Objective To investigate the ultrasonography value in the classification of appendicitis in children.Methods 90 patients suspected as appendicitis and diagnosed as appendicitis by ultrasonography,then the characteristics of ultrasonography were analyzed,classified and compared with pathological results.Results Among 90 patients,ultrasonographic diagnosis rate of appendicitis was 98.9%.The ultrasonographic images were： the appendixes thickened,the appendicle wall thickness and the mucous membrane coarse with echo interrupted or absent.Different of appendicle wall and echo reflected different pathological classification.There was 91.3% with acute appendicitis,97.8% with acute suppurative appendicitis,76.2% with acute gangrenous appendicitis and 100% with-periappendicular abscess.Conclusion H-Frequency ultrasonography is of high value for the diagnosis and classification of appendicitis in children,and can accurately estimate the extent of inflammatory changes and help clinicians to choose rational treatment.
