Ultrasonographic examination of the fetal abdomen is an integral part in all routine fetal sonograms and can provide significant information about the status and prognosis of the fetus. Although many types of fetal anomalies can be identified (i.e., gastroschisis, omphalocele, or congenital diaphragmatic hernia), there are several sonographic findings that are not clearly anomalous, but may be associated with poor fetal outcome. Echogenic fetal bowel, small or absent fetal stomach and fetal intra-abdominal calcifications all fall into this category. This article reviews the recent literature as it relates to these topics, including suggestions regarding the need for further action, and the types of further actions that are available to help identify abnormal fetuses and prevent unnecessary and/or invasive testing of normal ones.
胎儿腹部的超声检查是所有常规胎儿超声检查的一个组成部分，并且能够提供有关胎儿状况和预后的重要信息。虽然可以识别多种类型的胎儿异常（即腹裂、脐膨出或先天性膈疝），但有一些超声检查结果并不明显异常，但可能与不良胎儿结局相关。胎儿肠管回声增强、胎儿胃小或未显示以及胎儿腹腔内钙化均属于这一类。本文回顾了近期与这些主题相关的文献，包括关于进一步行动必要性的建议，以及有助于识别异常胎儿并防止对正常胎儿进行不必要和/或侵入性检查的可用进一步行动类型。
