先天性肠旋转不良的X线影像分析

The X- ray Imaging Features of Congenital Intestine Malrotation

目的探讨消化道造影检查对先天性肠旋转不起的诊断价值。方法回顾性分析21例手术证实为先天性肠旋转不良的X线影像改变。结果先天性肠旋转不葭患者腹部X线立住平片或透视，多数有“双泡征”。钡灌肠检查能显示盲肠、阑尾、升结肠位置异常。消化道碘荆或钡餐造影既能显示空肠上端固定性屈曲或螺旋状下降或空肠上端位置异常，其与十二指肠球在同一平面高度，同时还可以显示空回肠、盲肠、阑尾、升结肠位置异常。结论钡灌肠或，和钡餐检查对先天性肠旋转不良的诊断具有决定性价值。

Objective To discuss the roles of alimentary tract radiography in diagnosing congenital intestine malrotation. Method A retrospective analysis was done on the X - ray imaging features of the 21 cases which were diagnosed as congenital intestine malrotation by surgery. Results Under X- ray film or fluoroscopy, most of the patients with congenital intestine malrotation turned out to be ＂double- bubbled＂. The barium enema showed the abnormal location of cecum, appendix and ascending colon. The iodine or barium meal showed fixed flexion or corkscrew descending of superior part of jejunum, or abnormal location of superior part of jejunum, which rose up to the same height of duodenal bulb. At the same time, the abnormal location of cecum, appendix and ascending colon could also be seen. Conchusion Barium enema or/and iodine or barium meal is of decisive significance in the diagnosis of congenital intestine malrotation.
