目的分析并探讨超声诊断小儿肠套叠的声像图特征并总结规律。方法对我院64例患儿经B型超声诊断,探头经过腹部对腹腔内各脏器进行检查,主要检查实质性脏器情况以及腹腔内是否存在液性暗区,然后检查肠腔。并对具有手术对照的肠套叠患儿的超声图像做回顾性分析。结果本组64例经手术证实的肠套叠患儿经B型超声检查,未见假阳性病例。20例患儿有少量腹腔积液现象。小儿肠套叠的超声图像显示出典型的“套筒”与“靶环”特征。结论根据小儿肠套叠超声图像的特征性变化情况来对小儿肠套叠进行诊断,该方法具有简单、准确的优点,值得在临床上广泛推广。
Objective To analyze and discuss the ultrasonography features of intussusception in children and summarize the regularity. Methods 64 cases of our hospital diagnosed by B ultrasound, the probe through the abdomen of the abdominal organs were examined, the main check the situation of the substantive organs and the presence of liquid dark area within the abdominal cavity, and then check the intestine. Retrospective analysis was performed on ultrasound images of children with intussusception with surgical control. Results The group of 64 cases confirmed by intussusception in children with type B ultrasound examination, no false positive cases. 20 cases of children with a small amount of ascites phenomenon. The intussusception ultrasound image of a child shows the typical “sleeve” and “target ring” features. Conclusion The diagnosis of intussusception in pediatric intussusception is based on the characteristic changes of intussusception ultrasound images. The method has the advantages of simple and accurate, which is worth widely popularized in clinic.
