Umbilical cord
When does the development of abdominal wall occur?

14
This is a small defect involving all three layers of the abdominal wall, allowing the intestines to protrude into the amniotic cavity. It usually occurs to the right of the umbilical cord insertion and has no covering or membranous sack.
Gastroschesis
What are the possible abdominal wall defects in the fetus?
- Gastroschesis
2. Omphalocele
In order to see gastroschesis, the fetus must be imaged with the fetal abdomen in __________ plane. You must look above and below at the level of the umbilical cord insertion.
Transverse
Gastroschesis is a sporadic defect, not associated with ____________ ____________ or other abnormalities.
chromosomal abnormalities
This results from failure of the intestines to return to the abdomen during the second stage of intestinal rotation which occurs before the 14th week of life.
Omphalocele
With gastroschesis, when and why do complications arise?
Complications arise postnatally with these babies because bowel gets stuck together due to exposure of amniotic fluid. Frequently, bowel obstructions occur in the pediatric and infant years.
