An absent 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).
Pathology
Etiology
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
neuromuscular disorders
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.
