先天性肠旋转不良的影像学诊断

The Imaging Diagnosis on Congenital Intestinal Malrotation

目的探讨先天性肠旋转不良的影像学表现,提高对本病的认识。方法收集11例先天性肠旋转不良患者,8例与手术结果对照,总结其影像学表现。结果 11例患者其中7例可见"双泡征",全部病例表现十二指肠空肠连接处不过脊柱左侧,十二指肠水平段狭窄;2例十二指肠位于右腹部呈鸟嘴样狭窄,3例中肠螺旋状排列;10例表现为盲肠不在右下腹;1例表现为盲肠位置在右下腹,回盲瓣开口于盲肠右侧。结论十二指肠空肠连接处位置异常、盲肠不在右下腹部者,高度提示本病。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意义。

Objective Talking about the topic of Congenital intestinal malrotation in the performance of imaging feature to improve the understanding of this disease. Methods Through collecting 11 cases of patients with congenital intestinal malrotation and 8 of them were compared with surgical findings, Now we have summarized the imaging feature findings as follows. Resttlts Of the 11 patients, there are 7 cases showing ＂double-bubble sign＂, all the cases presented that the Duodenum jejunum junction didn＇t cross the left side of spine, and the level period of the duodenum is narrow; 2 cases of duodenum in the right abdomen showed a narrow shape with beak-like, 3 cases of midgnt showed the shape of spiral arrangement; 10 cases showed the cecum is not in the right lower Abdomen; 1 case showed the cecum is in the right lower Abdomen location, the opening of ileocecal valve is on the right side of cecum. Conclusion The sign that cecum is not in the right lower abdomen as well as with abnomal position of duodenal jejunum junction is the adequate evidence to show the disease. I think the examination with Barium enema or barium meal examination is decisive diagnosis on congenital intestinal malrotafion.
