目的探讨高频超声在小儿肠系膜淋巴结炎诊断及疗效评估中的作用。方法对在我院就诊的97例肠系膜淋巴结炎患儿的临床资料进行整理、分析、总结。对同期来我院查体的50例健康儿童行腹部超声检查，观察并记录小儿肠系膜淋巴结的分布、数目、大小及血流情况，分析并总结肠系膜淋巴结肿大的超声表现。结果97例患儿中肠系膜淋巴结多位于回盲部、脐周，多发，呈簇状堆积或呈串珠样分布，部分堆积呈团块状，淋巴结明显增大，呈椭圆形，血流信号较丰富，治疗后复查，肿大淋巴结减小，血流信号稀疏，纵径（L）、横径（S）及血流信号分级差异均有统计学意义（P＜0.05）。研究组与对照组肠系膜淋巴结的L、S及血流信号分级比较，差异均有统计学意义（P＜0.05），治疗后研究组与对照组肠系膜淋巴结的L、S及血流信号分级比较差异均无统计学意义（P＞0.05）。以S＞7 mm作为诊断小儿肠系膜淋巴结炎性肿大的标准，敏感性90.7%，特异性94.0%。结论高频超声用于小儿肠系膜淋巴结炎的诊断及疗效观察，客观准确。

高频超声曰小儿肠系膜淋巴结炎曰诊断曰急腹症

［Abstract］Objective To discuss the effects of high-frequency ultrasound on the diagnosis and evaluation of curative effects of pediatric mesentery lymphadenitis.Methods Clinical data of 97 children patients with mesentery lymphadenitis who were admitted to our hospital were collected，analyzed and summarized.50 health children who were given physical examination during the same period of time were given abdominal ultrasound examination.The distribution，number，size and blood flow of pediatric mesenteric lymph nodes were observed and recorded，and the ultrasound findings of enlarged mesenteric lymph nodes were analyzed and summarized.Results Mesenteric lymph nodes were located in peripheral umbilicus and ileocecal junction and multiple，and clustered or string beads distribution were shown.Some lymph nodes were stacked as crumby structure.The lymph nodes were significantly enlarged，shown in oval shape，and the signal of blood flow was relatively rich.In the re-examination after the treatment，the enlarged lymph nodes were reduced，and the signal of blood flow was sparse.The differences of longitudinal size（L），transverse diameter（S）and levels of blood flow signals were all statistically significant（P＜0.05）.In the comparative study on the healthy children，the differences of L，S and levels of blood flow signals of mesenteric lymph nodes in children patients and healthy children were statistically significant（P＜0.05）.The differences of L，S and levels of blood flow signals of mesenteric lymph nodes between children patients after the treatment and healthy children were not statistically significant（P＞0.05）.S＞7 mm was taken as the standard of diagnosing enlarged pediatric mesentery lymphadenitis，with the sensitivity of 90.7%and specificity of 94.0%.Conclusion High-frequency ultrasound is used for diagnosis and observation of curative effects of pediatric mesentery lymphadenitis，which is objective and accurate.
