【摘要】 目的：探讨小儿急性肠套叠的急诊超声诊断及其超声特点情况。方法：选择本院2016年1月-2018年1月由超声初诊为肠套叠的80例患儿进行研究，纳入对象均经临床综合诊断确诊，均有完整的X线诊断与急诊超声诊断资料，比较两种检查方法诊断结果，重点对急诊超声诊断进行回顾性分析，总结超声特点、治疗及随访情况。结果：超声诊断符合率为95.00%(76/80)，X线诊断符合率为67.5%(54/80)，超声诊断符合率明显高于X线诊断(P<0.05)。结论：小儿肠套叠大部分有典型的超声声像图特点，横断面多为“同心圆征”，纵切面多为“套筒征”，诊断快捷方便，符合率高，可为临床诊治提供不错的参考依据，值得在临床推广应用。
