超声、X线对小儿肠旋转不良合并中肠扭转的诊断效果

Diagnostic Effect of Ultrasound and X-ray in Children with Intestinal Malrotation Complicated with Midgut Torsion

目的:比较超声和X线对小儿肠旋转不良合并中肠扭转的诊断效果。方法:选取2020年1月—2023年9月东莞市第八人民医院收治的疑似小儿肠旋转不良合并中肠扭转患儿65例,均进行超声、X线诊断。以上消化道造影结果为“金标准”,分析超声、X线的诊断效能。结果:65例疑似小儿肠旋转不良合并中肠扭转患儿中,通过上消化道造影结果确诊阳性43例,阴性22例。超声诊断阳性40例,阴性25例;X线诊断阳性32例,阴性33例。超声诊断灵敏度、准确度高于X线,差异有统计学意义(P<0.05);超声、X线诊断特异度、阳性预测值、阴性预测值对比,差异无统计学意义(P>0.05)。结论:超声在小儿肠旋转不良及中肠扭转的诊断中表现出较高的灵敏度、准确度,相较于X线有显著优势。因此,推荐临床医生优先选择超声检查作为首选诊断方法,以提高早期诊断率。

Objective:To compare the diagnostic effect of ultrasound and X-ray in children with intestinal malrotation complicated with midgut torsion.Methods:A total of sixty-five suspected children with intestinal malrotation complicated with midgut torsion admitted to Dongguan Eighth People's Hospital from January 2020 to September 2023 were selected for ultrasound and X-ray diagnosis.The above gastrointestinal angiography results were"gold standard",and the diagnostic efficacy of ultrasound and X-ray were analyzed.Results:Among 65 suspected children with intestinal malrotation complicated with midgut torsion,43 positive cases and 22 negative cases were confirmed by upper gastrointestinal angiography;ultrasound diagnosis was positive in 40 cases and negative in 25 cases;X-ray diagnosis was positive in 32 cases and negative in 33 cases;the diagnostic sensitivity and accuracy of ultrasound were higher than that of X-ray,the difference was statistically significant(P<0.05);there was no significant difference in diagnostic specificity,positive predictive value and negative predictive value between ultrasound and X-ray(P>0.05).Conclusion:Ultrasound has shown higher sensitivity and accuracy in the diagnosis of intestinal malrotation and midgut torsion in children,and has significant advantages over X-ray.Therefore,it is recommended that clinicians preferentially choose ultrasound as the preferred diagnostic method to improve the early diagnosis rate.
