Perinatal Outcome of Fetal Echogenic Bowel: A Single-Center Retrospective Cohort Study

<p><strong>Objective:</strong> The aim of this study is to evaluate perinatal outcome of fetal echogenic bowel.<br /><strong></strong></p><p><strong>Study Design:</strong> In this retrospective cohort study, fetuses with echogenic bowel diagnosed and followed in our center between 2013-2017 were included. Fetuses and infants were evaluated in terms of antenatal comorbidities and postnatal persistent diseases. Infants were followed-up to June 2018 from time of diagnosis. Demographic questionnaire and face to face interview were used to obtain data including immune system diseases and respiratory system pathologies in infants. <br /><strong></strong></p><p><strong>Results:</strong> A total of 100 fetuses with echogenic bowel were included in the study. Fetal aneuploidy was detected in 7 (7%) cases. Trisomy 21 was the most common aneuploidy and identified in 4 (4%) cases. Other chromosomal disorders were tetrasomy 12p (1%), 69XXX (1%) and 46 XX, t (2,22) (9q9) (1%). A fetal echogenic bowel was associated with major congenital malformations in 25 (%25) cases. Cardiac abnormality was the most prevalent (%7). First and second trimester vaginal bleeding history was found in 5 pregnant women. In 3 case with isolated echogenic bowel (no congenital malformation and aneuploidy), lactose intolerance, celiac disease, and non-obstructive hydrocephalus were diagnosed in early childhood. <br /><strong></strong></p><p><strong>Conclusion:</strong> Isolated fetal echogenic bowel which can be considered as a soft marker for aneuploidy may be associated with lactose intolerance and celiac disease. Further clinical studies are warranted to evaluate this relationship.<br /><br /></p>
