上消化道造影检出儿童无症状肠旋转不良作用研究

目的]探讨上消化道造影（upper gastrointestinal imaging,UGI）常规检查十二指肠空肠曲（duodenojejunal flexure,DJF）位置的意义.方法]回顾性分析350例行UGI患儿的影像学资料,56例临床怀疑肠旋转不良的患儿,其余患儿根据是否检查DJF位置分为2组：A组198例检查了DJF位置,B组96例未检查DJF位置.记录患儿的年龄、性别、UGI的检查时间和DJF位置.结果]56例临床怀疑肠旋转不良的患儿有24例有DJF位置的异常（42.8％）,A组198例患儿仅有1例发现DJF位置异常（0.5％）.B组患儿的年龄和性别与A组比较差异无统计学意义（P＞0.05）.2组患儿UGI的检查时间比较差异有统计学意义（P＜0.01）.A组的检查时间显著大于B组.结论]本研究发现对临床没有怀疑肠旋转不良的患儿,UGI发现DJF位置异常的概率非常小,故儿童UGI可不常规检查DJF位置以降低辐射剂量.

The role of upper gastrointestinal contrast in diagnosing asymptomatic malrotation in children

Objective] To investigate the effect of upper gastrointestinal imaging（UGI） in examination of the orientation of duodenojejunal flexure （DJF） without clinical suspicion for malrotation.Methods] In retrospective materials,56 patients with clinical suspicion for malrotation were identified,and remaining children were grouped based on whether DJF was examined （Group A：n =198） or not （Group B.n=96）.Age,gender,screening time and the DJF position of patients are documented.Results]Abnormality of DJF was identified in 24 patients （42.8％）,but only 1 patient in Group A （0.5％）.Meanwhile,there without gender and age difference （P＞0.05）.Significant difference between Groups A and B in screening time was found （P＜ 0.01）.Conclusion]The routine examination for DJF position is not necessary for examination of the orientation of duodenojejunal flexure （DJF） without clinical suspicion for malrotation.
