■Omental梗塞是一种罕见的儿科疾病。超声是一种用于炎性病症(如阑尾炎)和网膜梗塞之间的非侵入性术前鉴别诊断的有用方式。特别是通过检测粘附在腹壁上的网膜的不动(“脂肪征”)。然而,这是一个动态标志,不能用B模式技术记录在静态图像中。这项工作的目的是将运动模式(M模式)的通用功能纳入网膜梗塞的诊断中,以描述M模式如何用于评估怀疑患有网膜梗塞的儿童的脂肪运动。2019年,我们提出了一种新的超声标志,名为“栓系脂肪标志”,用于准确无创诊断儿童网膜梗塞。在我们先前研究的234名儿童中,有6名观察到了这一发现,其中有4名腹腔镜确诊。
■从2019年1月到2021年7月,我们评估了195名儿童(91名男孩和104名女孩,从3到15年)因急性右侧腹痛入院于我们的Santobono-Pausilipon儿童医院。对所有患者进行腹部超声检查,并始终包括“束缚脂肪征”的调查。
■在7例患者中,超声显示存在位于右上腹部象限的高回声椭圆形肿块,在这些M模式中的2例记录了在呼吸运动过程中正常的肝下脂肪移动与腹壁。其余5例患者的网膜梗塞表现为在M模式下拴在腹壁上的肝下静止肿块。在这些患者中,每15d进行一次超声随访,随访2个月,显示右侧高回声肿块逐渐缩小.
■在对所有显示存在“系留脂肪标志”的儿童的评估中,M模式的使用在诊断超声中提供了经过认证的图像。
UNASSIGNED: Omental infarction is a rare pediatric disease. Ultrasound is a useful modality for a non-invasive pre-operative differential diagnosis between inflammatory conditions (as appendicitis) and omental infarction, especially by detecting immobility of the omentum adhered to the abdominal wall (\"tetherd fat sign\"). However, this is a dynamic sign that cannot be documented in a static image with B-mode technique. The goal of this work is to incorporate the versatile function of motion mode (M-mode) into omental infarction diagnosis to describe how the M-mode is useful in the evaluation of fat motion in children suspected of having omental infarction. In 2019 we suggested a new Ultrasound sign named \"tethered fat sign\" for an accurate non-invasive diagnosis of omental infarction in children. This finding was observed in 6 of the 234 seen children of our previous study with 4 laparoscopic confirmed diagnosis.
UNASSIGNED: From January 2019 to July 2021, we evaluated 195 children (91 boys and 104 girls, from 3 to 15 years) admitted to our Santobono-Pausilipon Children Hospital with acute right-sided abdominal pain. Abdominal ultrasound was performed to all the patients and the investigation of \"tethered fat sign\" was always included.
UNASSIGNED: In 7 patients ultrasound showed the presence of a hyperechoic oval mass localized in the right upper abdominal quadrant and in 2 of these M-mode documented a normal subhepatic fat moving during respiratory movements in relation with the abdominal wall. The remaining 5 patients had an omental infarction showed as a subhepatic motionless mass tethered to the abdominal wall on M-mode. In these patients, a sonographic follow-up was performed every 15 d for 2 months showing a progressive reduction in size of the right-sided hyperechoic mass.
UNASSIGNED: In the evaluation of all children who showed the presence of the \"tethered fat sign\" the use of M-mode provide a certified image in diagnostic ultrasound.
