Question Why polyhydramnios in congenital diaphragmatic hernia

Hi all:
Can someone please tell me why there is a history of polyhydramnios in patients suffering from diaphragmatic hernia? And why in these patients, chest radiographs reveal little or no gas in the abdomen.

Thank you!

Congenital diaphragmatic hernia will function like an obstruction and therefore the fetus cannot swallow amniotic fluid and therefore you'll have polyhydramnios.

There will be no gas in the abdomen because the abdominal viscera jumps up into the thorax in the case of diaphragmatic hernia.
