高频超声诊断儿童肠系膜淋巴结炎439例临床分析

Clinical Analysis of the Sonographic Findings and Clinical Features of 439 Cases Children with Mesenteric Lymphadenitis Diagnosed by High-frequency Ultrasound

目的分析肠系膜淋巴结炎患儿腹部淋巴结的超声声像图表现和临床特点,探讨高频超声对该病的诊断价值。方法将肠系膜淋巴结炎患儿439例作为病例组,同时随机选取同期100例健康正常儿童作为对照组。两组儿童行常规腹部高频彩色多普勒超声多切面扫查,记录淋巴结形态、大小及数量,对二维及彩色血流图像进行回顾性分析。结果病例组患儿右中下腹淋巴结的比例显著高于对照组(P<0.05),但对照组儿童脐周淋巴结的比例显著高于病例组(P<0.05)。病例组患儿肠系膜淋巴结纵径、横径及纵径/横径的比例都显著高于对照组(P<0.05)。结论高频超声可作为临床诊断儿童肠系膜淋巴结炎首选的影像学检查方法。

Objective To analyze 439 cases with children mesenteric lymphadenitis diagnosed by high-frequency ultrasound,to discuss the diagnosis of the disease to high-frequency ultrasound.Methods 439 cases children with mesenteric lymphadenitis were as case group,while randomly selected 100 cases healthy normal children at the same period as control group.All subjects were performed routine abdominal multi-section high-frequency ultrasound scanning with recording lymph node shape,size and number,and retrospectively analyzed two-dimensional and color flow images.Results The proportion of abdominal lymph nodes in case group was significantly higher than that in control group（P0.05）,but the proportion of cullen lymph nodes in control group was significantly higher than that in case group（P0.05）.The proportion with mesenteric lymph nodes of cases longitudinal diameter,transverse diameter and longitudinal diameter/transverse diameter in case group were significantly higher than those in control group（P0.05）.Conclusion High-frequency ultrasound can be as a clinical diagnosis of mesenteric lymphadenitis in children,is the preferred imaging method.
