Prenatal sonography has the potential to show a wide range of abnormalities in a fetus's gastrointestinal tract. Suspected fetal gastrointestinal abnormalities should be interpreted with caution, however, as the sonographic appearance of a healthy fetus's gastrointestinal tract is variable and there is considerable overlap in the appearances of normal and abnormal fetal bowel. Similarly, pathologic processes originating from organ systems other than the gastrointestinal tract can at times exhibit sonographic patterns remarkably similar to those of dilated bowel. This review examines the sonographic findings of gastrointestinal disorders seen in utero, emphasizing potential diagnostic pitfalls arising from confusion with normal anatomy, anatomic variants, and pathologic processes elsewhere in the fetus.
产前超声检查有可能显示胎儿胃肠道的多种异常情况。然而，对于疑似胎儿胃肠道异常的情况应谨慎解读，因为健康胎儿胃肠道的超声表现具有变异性，正常与异常胎儿肠道的表现存在相当大的重叠。同样，源自胃肠道以外器官系统的病理过程有时也会呈现出与扩张肠管极为相似的超声图像。本综述探讨了子宫内所见胃肠道疾病的超声检查结果，重点强调了因与正常解剖结构、解剖变异以及胎儿其他部位的病理过程相混淆而可能出现的诊断陷阱。
