Fetal Dextrogastria

The only structure of fetal gastrointestinal tract (GIT) which is seen on routine second trimester anomaly scan is the fetal stomach. Under normal conditions, the fetal stomach "bubble" is seen on the left side of the fetal abdomen. This is a normal finding on an ultrasound and indicates the stomach's normal position. There are two functions of the fetal GIT: 1. Propulsive action by peristalsis which takes the swallowed amniotic fluid up to the small bowel; 2. Absorption – the amniotic fluid is absorbed through the fetal small bowel. When the stomach is found prenatally to be located on the right side, it is called dextrogastria. Today in our high-risk prenatal clinic, we encountered a patient whose fetus was found to have this rare condition dextrogastria. Is this an isolated issue? What does this mean for clinical outcomes.
