摘　　要：目的分析新生儿阑尾炎的超声图像特征。方法回顾性分析我院经手术及病理证实为新生儿阑尾炎病例18例,总结其声像图特征。结果16例(16/18,88.9%)超声显示阑尾,其中肝下缘或右肾旁10例(10/16,62.5%);15例(15/16,93.8%)阑尾壁厚<2 mm;11例(11/16,68.8%)阑尾外径<6 mm;16例阑尾腔扩张积脓但均未发现粪石;14例(14/16,87.5%)网膜增厚不明显;16例均出现阑尾壁模糊,周围系膜水肿增厚;8例出现肠间隙积脓或脓肿形成。结论新生儿阑尾炎临床表现不典型。超声特征为:(1)新生儿阑尾多位于肝下缘或右肾旁;(2)阑尾壁模糊但增厚不明显多<2 mm;(3)阑尾外径增粗多<6 mm;(4)阑尾腔扩张积脓一般无粪石;(5)阑尾周围大网膜增厚一般不明显;(6)阑尾周围系膜水肿增厚,多合并肠间隙积脓或脓肿。超声可较准确诊断新生儿阑尾炎,为临床早期干预提供可靠影像学依据。Objective To analyze the ultrasonographic features of neonatal appendicitis.Methods 18 cases of neonatal appendicitis confirmed by operation and pathology in Tianjin Children′s Hospital were analyzed retrospectively.Results 16 cases(16/18,88.9%)showed appendicitis,including 10 cases(10/16,62.5%)with lower edge of liver or right side of kidney;15 cases(15/16,93.8%)with wall thickness of less than 2 mm;11 cases(11/16,68.8%)with outer diameter of less than 6 mm;16 cases with appendiceal cavity dilatation and empyema,but no fecal stone was found;14 cases(14/16,87.5%),the thickening of omentum was not obvious,the wall of appendix was indistinct in 16 cases,the edema and thickening of peripheral mesentery in 8 cases,and the formation of empyema or abscess in intestinal space in 8 cases.Conclusions The clinical manifestation of neonatal appendicitis is not typical.The ultrasonic features are as follows:(1)The appendix of the newborn is mostly located at the inferior margin of the liver and the right kidney;(2)The wall of the appendix is blurred but not obviously thickened<2 mm;(3)The outer diameter of the appendix is thickened less than 6 mm;(4)there is generally no fecal stone in the dilated pus of the appendiceal cavity;(5)The thickening of the surrounding omentum is generally not obvious.(6)The mesenteric edema around the appendix is thickened,and it is often complicated with abscess or abscess of interintestinal space.Ultrasound can accurately diagnose neonatal appendicitis and provide reliable imaging basis for early clinical intervention.
