Non-visualization of the fetal stomach on ultrasound can occur with various physiological as well as pathological processes. It becomes a significant sonographic observation >14 weeks of gestation (about the time the fetus begins to swallow).
Causes include:
- physiological emptying: transient
- lack of amniontic fluid to swallow
- oligohydramnios and its various causes
- anhydramnios and its various causes
- impaired fetal swallowing
- certain forms of esophageal atresia: particularly those without a tracheo-esophageal fistula
- obstructing oropharyngeal mass
- CNS abnormalities
- facial clefts
- neuromuscular disorders
- microgastria
- congenital diaphragmatic herniation: fetal stomach may be absent in an axial ultrasound scan - standard view due to migration into the thorax
If there is non-visualization of the fetal stomach >18 weeks, there is an 85% chance of an abnormality.
