Chapter 17: GIT- Congenital Abnorm- Diaphragmatic Hernia, Omphalocele & Gastroschisis

Question 1

When does Diaphragmatic hernia occurs?

Answer 1

when incomplete formation of the diaphragm allows the abdominal viscera to herniate into the thoracic cavity.

Question 2

When Diaphragmatic hernia is severe, the space-filling effect of the
displaced viscera can cause what?

Answer 2

pulmonary hypoplasia

that is incompatible with life after birth.

Question 3

When does Omphalocele occurs?

Answer 3

when closure of the abdominal musculature is incomplete and the
abdominal viscera herniate into a ventral membranous sac.

This may be repaired surgically, but
as many as 40% of infants with an omphalocele have other birth defects, including
diaphragmatic hernia and cardiac anomalies.

Question 4

In as many as 40% of infants with an omphalocele have other birth defects, including what?

Answer 4

diaphragmatic hernia and cardiac anomalies.

Question 5

What is Gastroschisis?

Answer 5

is another ventral wall defect similar
to omphalocele except that it involves all of the layers of the abdominal wall, from the
peritoneum to the skin.

Question 6

What are the two ventral wall defects congenital anomaly?

Answer 6

Omphalocele, and Gastroschisis

Gastrochisis ( all the layers of the abdominal wall )
