彩超观测小儿肠系膜淋巴结的临床价值

目的：探讨超声观测肠系膜淋巴结的临床价值。方法：研究对象分为两组，一组为腹痛就诊小儿，另一组为在校儿童查体；采用高分辨率彩超全面检查小儿腹腔，重点观察肠系膜淋巴结并测量其大小。结果：因腹痛就诊小2儿1072例，发现肠系膜淋巴结的739例（占68．94％），查体儿童258例，发现肠系膜淋巴结的167例（占64．73％），两组肠系膜淋巴结检出率和单一最大截面指数的差异均有显著性意义（P＜0．05）。22例病理结果证实，肿大的淋巴结为炎症。结论：肠系膜淋巴结肿大多数是淋巴结急性或慢性炎症引起，最大截面指数可用于肿大的判断。

Clinical Evaluation of Color Doppler Sonography in the Mesenteric Lymph Nodes of the Child

Objective To investigate clinical value of ultrasonography in mesenteric lymph nodes. Methods The research objects were divided into two groups: the first group was the children seeing a doctor for abdominal pain; the second group was the children in school for physical examination. The abdominal cavities were examined with high resolution color Doppler ultrasound, especially pay attention to mesenteric lymph nodes and measure its size. Results The first group had 1072 cases, the mesenteric lymph nodes had been found in 739 (68.94%), the second group had 258 cases, the mesenteric lymph nodes had been found in 167 (64.73%). The difference from the finding rate and maximum area index of the mesenteric lymph nodes was significant ( P <0.05). The enlargement of the mesenteric lymph nodes was caused by inflammation,that had been confirmed by the results of 22 cases. Conclusion The enlargement of the mesenteric lymph nodes was almost caused by its acute or chronic inflammation. The index of maximum area is useful for diagnosing of the enlargement of mesenteric lymph nodes.
