摘　　要：目的分析高频超声对儿童肠道蛔虫症的诊断价值。方法选取2015年5月至2018年12月中航工业西安医院与陕西省森工医院收治的疑似肠道蛔虫症儿童86例为研究对象,均行病原学检查、血常规检查及高频超声检查,分析其超声影像特点,并以临床确诊结果为金标准,比较不同检查方法的诊断价值。结果86例患儿中,经临床确诊为肠道蛔虫症60例(69.77%),其中小肠蛔虫31例(51.67%)、空肠蛔虫14例(23.33%)、回肠蛔虫4例(6.67%)、十二指肠蛔虫11例(18.33%),非肠道蛔虫症26例(30.23%)。病原学检查显示肠道蛔虫症43例,诊断准确43例;血常规检查示肠道蛔虫症52例,诊断准确44例;高频超声检查示肠道蛔虫症54例,诊断准确53例;高频超声诊断肠道蛔虫症的灵敏度高于病原学检查、血常规检查,高频超声、病原学检查诊断特异度高于血常规检查(P<0.05)。结论高频超声对儿童肠道蛔虫症有较高诊断价值,其诊断灵敏度、特异度、准确度明显提高,且具有典型超声影像学特点,有临床推广价值。Objective To analyze the diagnostic value of high-frequency ultrasound for intestinal ascariasis in children.Methods A total of 86 children with suspected intestinal ascariasis admitted to Xi′an Hospital of Aviation Industry of China(AVIC)and Shaanxi Sengong Hospital from May 2015 to December 2018 were selected as the study subjects and conducted the etiological examination,blood routine examination and high-frequency ultrasound examination.The features of the ultrasound images were analyzed.With the clinical definite diagnosis results as the golden standard,the diagnostic values were compared among different examination methods.Results Among the 86 children patients,there were 60 cases(69.77%)with intestinal ascariasis definitely diagnosed by clinic,including 31 cases(51.67%)of small intestine ascarid,14 cases(23.33%)of jejunum ascarid,4 cases(6.67%)of ileum ascarid,11 cases(18.33%)of duodenum ascarid,and 26 cases(30.23%)of non-intestine ascariasis.The etiological examination showed 43 cases of intestinal ascariasis,and all cases were diagnosed accurately.Blood routine showed 52 cases of intestinal ascariasis,and 44 cases were diagnosed accurately.High-frequency ultrasound showed 54 cases of intestinal ascariasis,and 53 cases were diagnosed accurately.The sensitivity of high-frequency ultrasound for diagnosing intestinal ascariasis was higher than that of etiological examination or blood routine.The diagnostic specificities of high-frequency ultrasound and etiological examination were higher than that of blood routine(P>0.05).Conclusion The high-frequency ultrasound has relatively higher diagnostic value for child intestinal ascariasis.Its diagnostic sensitivity,specificity and accuracy are significantly improved with typical ultrasound imaging features,which has the clinical promotion value.
