高频超声在小儿便血病因判断中的应用价值

Application value of high frequency ultrasound in judgment of cause of hematochezia in children

目的探讨高频超声在小儿便血病因判断中的应用价值。方法回顾性分析我院2011年5月至2012年5月80例小儿便血患者的临床资料,所有患者均经病理学诊断确诊,采用高频超声检测(我院使用机器为:GEVoluson E8)与病理学诊断结果进行对比,分析高频超声在小儿便血病因判断中的应用价值。结果高频超声检查诊断出24例息肉患儿,诊断准确率为88.89%;诊断出22例美克尔憩室,诊断准确率为84.62%;诊断出13例肠套叠患儿,诊断准确率为100%;诊断出6例过敏性紫癜病史患儿,诊断准确率为100.00%;诊断出4例肠重复畸形患儿,诊断准确率为80.00%;诊断出4例坏死性小肠结肠炎患儿,诊断准确率为80.00%。高频超声对结肠息肉、肠套叠、肠重复畸形、坏死性小肠结肠炎及过敏性紫癜病史的诊断准确率与病理学诊断的准确率比较差异无统计学意义(P>0.05);高频超声对美克尔憩室的诊断准确率低于病理学诊断的准确率,差异有统计学意义(P<0.05)。结论高频超声在结肠息肉、美克尔憩室、肠套叠、过敏性紫癜、坏死性小肠结肠炎及肠重复畸形等疾病引起的小儿便血有重要的诊断价值,尤其是结肠息肉、肠套叠、过敏性紫癜、坏死性小肠结肠炎及肠重复畸形等病因中诊断价值较高,可在临床推广使用。

Objective Application value of high frequency ultrasound in judgment of cause of hematochezia in children. Methods A retrospective analysis of clinical data was carried out in 80 children with hematochezia from May 2011 to May 2012, all patients were confirmed by pathological diagnosis, results of high frequency ultrasound and pathological diagnosis were compared to analyze application value of high frequency ultrasound in judgment of cause of hematochezia in children. Results High frequency ultrasound diagnosed 24 children with polyps, diagnostic accuracy was 88.89%; diagnosed 22 meckel＇s diverticulum, diagnostic accuracy was 84.62%; diagnosed 13 children with intussusception, diagnostic accuracy was 100%; diagnosed 6 children with a history of allergic purpura, diagnostic accuracy was 100.00%; diagnosed 4 children with intestinal duplication, diagnostic accuracy was 80.00%; diagnosed 4 children with necrotic enterocolitis, diagnostic accuracy was 80.00%. There was no significant difference in diagnostic accuracy of high frequency ultrasound and pathological diagnosis in polyp of colon, intussusception, intestinal duplication, necrotic enterocolitis and history of allergic purpura （P〉 0.05）; diagnostic accuracy of high frequency ultrasound in meekel＇s diverticulum was significantly lower than pathological diagnosis （P〈0.05）. Conclusion High frequency ultrasound has important diagnostic value in chil- dren with hematochezia caused by polyp of colon, meckel＇s diverticulum, intussusception, allergic purpura, necrotic enterocolitis, intestinal duplication, especially has higher diagnostic value in polyp of colon, intussusception, allergic purpura, necrotic enterocolitis, intestinal duplication, can be used widely in clinical works.
