摘　　要：目的应用超声对儿童复发性肠套叠与肿大的肠系膜淋巴结的关系进行评价。方法回顾性分析35例复发性肠套叠患儿(共复发75次)的超声声像图特点,观察肿大的肠系膜淋巴结的位置、形态、排列状态并记录其数目、大小。结果 35例复发性肠套叠患儿(共复发75次)中,20例患儿分别于肠套叠声像图的横断面"靶环"征及纵断面"套筒"征的套叠部肠管肠系膜内和(或)套叠部周围肠管肠系膜内探及3个(含3个)以上肿大的肠系膜淋巴结,占57.1%(20/35)。肿大的肠系膜淋巴结均呈回声均匀、光滑的椭圆形低回声结节,中央髓质部呈高回声。其最大纵径为7～20mm,最大横径为3～8mm,纵横比值≥2。结论肿大的肠系膜淋巴结是引起儿童肠套叠复发的至关重要因素之一。超声检查不仅能准确、及时地早期诊断肠套叠,同时还能扫查到肿大的肠系膜淋巴结,能为临床诊断和治疗提供重要依据,从而减少肠套叠的复发。Objective To evaluate the relationship between recurrent intussusception and enlarged mesenteric lymph nodes （EMLNs） in children by ultrasound. Methods A total of 35 cases （a total of 75 relapse） with imaging features of recurrent intussusception were retrospectively analysed. The sequence,size,number,morphology and location of EMLNs were recorded. Results Twenty cases of EMLNs were found in 35 cases recurrent intussusception （57.1%,20/35）. At least three EMLNs were found in and/or around the mesentery of intussusception. The imaging feature of recurrent intussusception was a ＂ target＂ appearance on transverse scans and a ＂sleeve＂ sign on longitudinal scans. All the EMLNs were smooth and oval-shaped hypoechoic nodule. The largest longitudinal diameter of the EMLNs ranged between 7-20 mm,the largest transverse diameter of the EMLNs ranged between 3-8 mm with the aspect ratio≥2.0. Conclusion The Enlarged mesenteric lymph node recurrence of intussusception in children is crucial factor. Ultrasound can not only accurately and timely diagnose and treat intussusception while scanning enlarged mesenteric lymph nodes,which can provide an important basis for reducing the recurrence of intussusception.
