A rare case of small bowel malrotation occurring in each of a pair of identical twins is presented. The conflicting evidence in the literature regarding possible hereditary influences is reviewed. This case raises the intriguing question of whether this disorder is due to a prenatal insult, an autosomal recessive gene, or a new autosomal dominant mutation. If one identical twin is found to have a small bowel malrotation, the authors strongly advise that the other twin be screened.
本文报道了一对同卵双胞胎均发生小肠旋转不良的罕见病例。文中回顾了文献中关于可能的遗传影响的相互矛盾的证据。该病例引发了一个有趣的问题，即这种疾病是由于产前损伤、常染色体隐性基因还是新的常染色体显性突变所致。如果发现一名同卵双胞胎患有小肠旋转不良，作者强烈建议对另一名双胞胎进行筛查。
