Abstract
An 8-year-old boy with intestinal malrotation is reprted on herein. He was admitted to our hospital because of abdominal pain with bilious vomiting. In an upper GI series, a complete obstruction at the duodenal 3rd portion and the dilatation of the proximal duodenal loop, which looked like a C-loop, were recognized. A barium enema showed no abnormal signs. In a second upper GI series, he was diagnosed as having intestinal malrotation due to the finding of an abnormal position of the duodeno-jejunal loop running towards the right side. He was treated successfully with Ladd's operation with an incidental appendectomy. The postoperative course was satisfactory and no sympotoms have recurred. We reviewed the diagnostic procedures of intestinal malrotation in older children. Although the upper GI series is favored by most pediatric surgeons and radiologists, we must recognize and pay attention to false negative findings such as those seen in our case.
