目的:观察及分析诊断小儿肠旋转不良并中肠扭转中运用超声的效果情况.方法:选取患儿60例纳入研究,全部属于小儿肠旋转不良并中肠扭转者.为了观察超声诊断的效果,本研究中对这些患儿进行两种诊断方法,即超声和X线造影诊断.对于两种方式的诊断效果进行比较,分析超声诊断的价值.结果:60例患儿经手术病理确诊.超声诊断一共有具有58例被检出,获得96.67％的诊断符合率;X线造影一共有46例被检出,获得到了76.67％的诊断符合率.结果显示超声诊断的优势更明显,P < 0.05;记录两种方式诊断效能,超声诊断结果的诊断“,”Objective: To observe and analyze the effect of ultrasound in the diagnosis of intestinal malrotation and midgut torsion in children. Methods: 60 children with intestinal malrotation and midgut torsion were selected for the study. In order to observe the effect of ultrasound diagnosis, two diagnostic methods were used in these children, namely ultrasound and X-ray contrast diagnosis. The diagnostic effects of the two methods were compared to analyze the value of ultrasound diagnosis. Results: 60 cases were confirmed by operation and pathology. A total of 58 cases were detected by ultrasonography, and the diagnostic coincidence rate was 96.67％; A total of 46 cases were detected by X-ray angiography, and the diagnostic coincidence rate was 76.67％. The results showed that the advantages of ultrasound diagnosis were more obvious (P<0.05); The diagnostic accuracy, specificity and sensitivity of ultrasound were higher than those of X-ray angiography (P<0.05); The imaging findings showed that ultrasound showed typical or atypical vortex sign in the upper abdomen, medium mass echo, intestinal effusion, intestinal wall edema, SMV expansion, and insufficient vascular blood flow in the intestinal wall. Conclusion: For the clinical diagnosis of intestinal malrotation and midgut torsion in children, the scheme of ultrasonic diagnosis can be implemented, which can obtain high detection rate, clear image and promote effective treatment as soon as possible.
