目的: 评价腹部平片对婴儿肠旋转不良合并中肠扭转的诊断价值。材料与方法: 经手术证实的婴儿肠旋转不良合并中肠扭转共16 例,结合手术病理回顾性分析其腹部平片表现。结果: (1) 十二指肠完全性梗阻16 例,呈双球征13 例,三球征3 例。(2) 管状充气、狭细短跨度伴肠壁增厚肠段15 例。局限于右中上腹9 例,中上腹5 例,左上腹1 例。(3) 广泛充气扩张管形壁厚肠段,腔内有浅液面,类似小肠低位梗阻1 例。结论: 腹部平片简便易行,能迅速提供肠道气体的异常信息。通过腹部平片反映本病的两个特殊病理,包括十二指肠机械梗阻和中肠扭转的动力性损害。结合空肠袢异位征象,即肠袢局限偏侧分布特征,能对本病作出早期诊断,及时手术避免肠坏死的致命后果
Objective: To evaluate the diagnostic value of abdominal plain film in the diagnosis of malrotation of midgut in infants with intestinal malrotation. Materials and Methods: Totally 16 cases of infantile intestinal malrotation combined with midgut torsion confirmed by operation were retrospectively analyzed for their abdominal plain radiographs. Results: (1) Complete duodenal obstruction in 16 cases, showing double ball sign in 13 cases, three ball sign in 3 cases. (2) tubular inflatable narrow narrow span with intestinal wall thickening of the bowel in 15 cases. Limited to the right middle abdomen in 9 cases, 5 cases in the upper abdomen, 1 case of the left upper abdomen. (3) a wide range of inflation dilated tubular wall segment, cavity shallow liquid, similar to intestinal obstruction in 1 case. Conclusion: The plain radiographs are simple and easy to provide the information of intestinal gas abnormalities rapidly. Two specific pathologies of the disease are reflected by plain radiographs, including duodenal mechanical obstruction and motility damage of midgut torsion. Combined with ectopic signs of jejunum,, that is, limited distribution of bowel obstruction, can make early diagnosis of this disease, timely surgery to avoid the deadly consequences of intestinal necrosis
