高频超声对小儿急性肠系膜淋巴结炎的研究

目的探讨高频超声在诊断小儿急性肠系膜淋巴结炎中的价值。方法使用高频超声探头加压动态观察125例急性肠系膜淋巴结炎经抗感染治疗后10～15天超声复查,观察治疗前后淋巴结的超声变化。结果小儿急性肠系膜淋巴结炎典型的声像图特征是右侧中下腹部见数枚大小不等椭圆形低回声结节。治疗后10～15天复查肿大淋巴结有不同程度缩小,治疗前后淋巴结大小变化非常显著。结论高频超声可作为诊断小儿急性肠系膜淋巴结炎的首选方法。

Objective To evaluate the diagnostic value of high frequency ultrasonography in acute mesenteric lymphadenitis. Methods High frequency ultrasonography was used to examine 125 acute mesenteric lymphadenitis and the patients were reexamined 10 to 15 days after therapy.The sonographic appearances were analyzed before and after therapy. Results The typical sonographic appearances were the presence of multiple enlarged lymph nodes shown as oval hypoechoic nodules with different size in the right inferior abdomen. The enlarged lymph nodes diminished in different degree 10 to 15 days after therapy and the difference before and after treatment was very significant. Conclusions High frequency ultrasonography may be the first choice of imaging examination in the diagnosis of acute mesenteric lymphadenitis.
