Antenatal diagnosis of jejunal atresia by 3D HDlive ultrasound: Case report and literature review

Abstract

Objectives: To report the case of a patient with a prenatal diagnosis of jejunal atresia and to review the literature regarding the results and prenatal diagnosis of this entity, implementing the use of non-conventional methods (3D ultrasound or magnetic resonance imaging). Material and methods: Report of a case of an 18-year-old pregnant woman referred to the Maternal-Fetal Medicine, Genetics and Reproduction Unit of the Virgen del Rocío Hospital in Seville due to fetus with abdominal peristaltic cystic image, consistent with jejunal atresia, confirmed with 3D HDLive mode ultrasound. A bibliographic search was carried out in Medline/PubMed, Google Scholar and LILACS, restricting by type of language (English and Spanish) and date of publication (January 1995 to June 2020). Primary studies of reports and case series relating to the outcome and prenatal diagnosis of this pathology were included. Results: The search identified 1,033 titles, of which four studies met the inclusion criteria, these being reports or case series. A total of twelve fetuses with a prenatal diagnosis of jejunal atresia detected with unconventional methods were reported. In all cases, the prenatal diagnosis was confirmed during the neonatal period, which required resection of the compromised segment; one of them died and two neonates developed short bowel syndrome because of a wide bowel resection. The postoperative course in the remaining cases was favorable. Conclusion: The available literature on the prenatal diagnosis of jejunal atresia using non-conventional methods is scarce and is limited to case reports or case series. The literature reviewed suggests that, in the presence of intestinal dilation, 3D ultrasound and magnetic resonance imaging could be of some use in characterizing the atretic portion and establishing the differential diagnosis. More studies are required to evaluate the diagnostic utility of these two alternatives.
