【摘要】 目的:探讨高频超声检查在小儿肠系膜淋巴结炎诊断中的临床价值。方法:应用东芝Aplio 500高频探头(5~12MHz)扫查患儿全腹部,仔细观察脐周及右下腹部,记录患儿肠系膜淋巴结数目、大小、形态及内部回声情况,同时,观察有无其他腹部异常。纵径>0.5 cm为淋巴结肿大。结果:病例组130例急性腹痛患儿肠系膜淋巴结显示率为100%。肿大淋巴结均位于右下腹或脐周部,其中肿大淋巴结数目>5个124例(95.4%)。50例经两周后超声复查,淋巴结无明显变化30例、减小20例。结论:高频探头可以清晰显示小儿肠系膜淋巴结,能够为肠系膜淋巴结炎临床诊断及鉴别诊断提供可靠的客观依据。更多还原

【Abstract】 Objective: To investigate clinical value of high frequency ultrasonography in the diagnosis of mesenteric lymphadenitis. Methods: The children’s abdomen were carefully scanned by using Toshiba Aplio 500 high frequency ultrasound(5~12 MHz), special attention was paid to the umbilical area and the right lower abdomen. The number, size, shape and internal echo of the mesenteric nodes were observed and recorded, meanwhile also observed whether there were other abdominal abnormalities. The longitudinal diameter of the lymph nodes above 0.5 cm was considered enlarged. Results: In 130 children with acute abdominal pain, the demonstration rate of lymphadenitis was 100%. Enlarged lymph nodes were located in the right lower quadrant or in the navel area. In 124 cases(95.4%) the number of enlarged lymph nodes more than 5. In 50 cases a second ultrasound examination were performed after two weeks, the mesenteric lymph nodes showed no change in 30 cases, size of the enlarged nodes reduced in 20 cases. Conclusion: High frequency ultrasound not only can display the pediatric mesenteric lymph node clearly, but also can provide reliable evidence for clinical diagnosis and differential diagnosis of mesenteric lymphadenitis.更多还原
