RESUMO
ObjectiveTo evaluate the diagnostic value of CT in adults with midgut malrotation.MethodsThe CT and clinical findings of 13 cases confirmed by surgery were analyzed retrospectively.ResultsCT found “whirl sign” in 9 cases,“transposition sign” in 5 cases,and the superior mesenteric vein located in right lower abdomen in 4 cases.At the same time,duodenum and upper jejunum located in right upper abdomen.Conclusion“Whirl sign” and “transposition sign” were the typical CT findings of midgut malrotation in adults.Ectopic superior mesenteric vein highly indicated slight midgut malrotation in adults.
RESUMO
Objective To evaluate the X-ray diagnosis value of intestinal malrotation in adults.Methods The X-ray findings of 16 cases with intestinal malrotation confirmed by surgery were analyzed retrospectively. All of them were taken X-ray plain films, 11 cases were taken alimentary tract barium meal,and 5 cases were taken barium enema. Results Eight cases were found incomplete obstruction of the duodenum, and 2 cases were found low small intestine obstruction on the X-ray plain films. The alimentary tract barium meal showed 4 cases with dilatation and incomplete obstruction of the duodenal bulb to horizontal segment,and the distal end of narrowing intestine appeared as a rat tail,7 cases showed the abnormal duodenal location and shape,called "strip" sign. Four cases were found abnormal duodenojejunal flexure by barium enema examination. Conclusion The alimentary tract barium meal and barium enema examination has great diagnosis value for intestinal malrotation in adults.
