摘要
目的对比分析胃肠彩超、腹部X线平片、CT平扫与空气灌肠用于小儿肠套叠诊断及复位效果评估。方法回顾分析2016年1月至2018年5月于我院就诊治疗的62例小儿肠套叠患儿临床、影像资料,比较不同检查方法对小儿肠套叠的检出率及诊断灵敏度和特异性,总结小儿肠套叠的影像特征。结果胃肠彩超诊断小儿肠套叠的灵敏度和特异性均显著高于腹部X线、CT平扫和空气灌肠,而CT平扫和空气灌肠诊断小儿肠套叠的灵敏度和特异性均高于腹部X线平片(P<0.05);胃肠彩超示:腹部可探及不均匀低回声包块,包块轮廓模糊,可见套筒征;腹部X线平片表现为官腔狭窄,具有较差的扩张性;CT平扫可表现出靶征、慧星尾征、套筒征、肾形征及不规则肿块征等征象;而空气灌肠造影示病变肠道远端部可见软组织影,显示杯口征象。结论胃肠彩超检查对小儿肠套叠的诊断具有较高的灵敏度和特异性,而在复位治疗后监测中,CT平扫和空气灌肠造影检查可较为清晰的显示其图像,为预后评估提供进一步的理论依据。
Objective To compare and analyze effect of gastrointestinal color Doppler ultrasound,abdominal X-ray film,CT plain scan and air enema for the diagnosis and reduction effect of pediatric intussusception.Methods The clinical and imaging data of 62 children with intussusception treated in our hospital from January 2016 to May 2018 were retrospectively analyzed.The detection rate and diagnostic sensitivity and specificity of different examination for pediatric intussusception were compared.The imaging features of pediatric intussusception were summarized.Results The sensitivity and specificity of gastrointestinal color Doppler ultrasound in the diagnosis of pediatric intussusception were significantly higher than those of abdominal X-ray films,CT plain scan and air enema.The sensitivity and specificity of CT plain scan and air enema in the diagnosis of pediatric intussusception were higher than those of abdominal X-ray films(P<0.05).Gastrointestinal color ultrasonography showed the abdomen can be detected with uneven hypoechoic mass,the contour of the mass was blurred,and the sleeve sign can be seen.Abdominal X-ray plain film showed stenosis of cavity with poor distensibility.CT plain scan can show signs such as target sign,comet tail sign,sleeve sign,kidney shape sign and irregular mass sign.The air enema angiography showed that distal end of the diseased intestine can be shown with soft tissue shadows,showing signs of cup mouth.Conclusion Gastrointestinal color Doppler ultrasonography has higher sensitivity and specificity in the diagnosis of pediatric intussusception.In the monitoring after reduction treatment,CT plain scan and air enema angiography can clearly display the image and provide further theoretical basis for prognosis evaluation.
