Intestinal malrotation is a congenital abnormal fixation of the bowel that predisposes to life threatening midgut volvulus. Most events of midgut volvulus occur in the first month of life with decreased risk with age. The most typical presentation is bilious vomiting. Upper gastrointestinal series is the study of choice for diagnosis of malrotation. For optimal results, the study should be well planned with meticulous attention to technique. In equivocal cases, small bowel follow-through study and ultrasound can be performed.
肠旋转不良是一种肠道先天性固定异常，易导致危及生命的中肠扭转。大多数中肠扭转事件发生在出生后的第一个月，随着年龄增长风险降低。最典型的表现是胆汁性呕吐。上消化道造影是诊断旋转不良的首选检查。为获得最佳结果，该检查应精心规划并严格注意技术细节。在诊断不明确的情况下，可进行小肠钡剂灌肠检查和超声检查。
