Fetal stomach bubble was identified and fetal situs was determined by identifying left and right sides of the fetus.

Chest x-ray revealed dextrocardia and right-sided stomach bubble
A stomach bubble

In a study by Stringer et al (3) the positive predictive value of an absent stomach bubble and polyhydramnios was 56%.
Satoh et al (6) extended these preliminary findings to all cases with both polyhydramnios and a small or absent stomach bubble.
