Abstract
ABSTRACT Aim To evaluate the role of second mid-trimester ultrasound in prenatal detection of gastrointestinal (GI) fetal anomalies and compare the ultrasonographic findings with postnatal diagnosis. Materials and methods A 5-year retrospective study included 16,334 neonates delivered at a tertiary referral center. All neonates were evaluated by a second mid-trimester 2D ultrasound fetal anatomy scan. Patients with abnormal findings on 2D scan were also examined by 3D ultrasound. Postnatally confirmed GI anomalies were compared with prenatal ultrasound assessment of two sections of fetal abdomen which had analyzed the presence, size and position of the stomach, umbilical cord insertion and have assessed the amniotic fluid index (AFI). Results Prenatal ultrasound revealed 28 out of 38 fetal GI anomalies (73.6%). All GI anomalies initially diagnosed with 2D ultrasound were confirmed by 3D ultrasound. The major advantage of multiplanar imaging was more comprehensive anatomical information about GI anomalies. Surface rendering provided additional information in evaluating fetuses with anterior abdominal wall defects. Conclusion Our data indicate that standard planes obtained by 2D ultrasound can rule out a majority of fetal GI anomalies. Assessment of AFI should be an integral part of prenatal ultrasound scan in detection of GI anomalies, particularly in GI obstruction.
