超声对先天性肠旋转不良并中肠扭转的诊断价值

摘要

Objective:To explore the value of ultrasonic diagnosis of intestinal malrotation and midgut volvulus. Method:Col-lect data of 42 cases congenital intestinal malrotation of children confirmed by surgery,and the ultrasonic diagnosis and surgical results were analyzed. Results:In 42 cases intestinal malrotation of children confirmed by surgery,36 cases were with volvulus (85.7%). Ultrasound diagnosis of intestinal malrotation were 34 cases (all with volvulus),the sensitivity was 94.4% (34/36). 8 cases of misdiagnosis,including 6 cases of unincorporated volvulus in children with ultrasound were not checked out. Conclu-sion:Color Doppler ultrasound can make the diagnosis of the disease by showing the positional relationship between the superior mesenteric artery and the superior mesenteric vein and the spiral soft tissue mass in the upper abdomen,and can be used as the first choice for the preoperative diagnosis. But for those who do not merge midgut volvulus,the diagnosis ability of ultra-sound is limited,and should be combined with X-ray imaging and other inspection association.%目的:探讨超声对先天性肠旋转不良并中肠扭转的诊断价值.方法:收集42例先天性肠旋转不良患儿的临床资料,并将超声诊断结果与手术结果进行对比分析.结果:42例中,36例合并中肠扭转(85.7%).超声诊断肠旋转不良34例(均合并中肠扭转),敏感度94.4%(34/36);漏诊8例;6例未合并中肠扭转的患儿超声未检出.结论:彩色多普勒超声可通过显示肠系膜上动脉与肠系膜上静脉的位置关系,以及中上腹部螺旋状的软组织团块影对该病作出明确诊断,可作为术前诊断的首选检查方法.但对不合并中肠扭转的肠旋转不良患儿,超声诊断能力有限,需结合X线造影等其他检查协助诊断.
