Definition
a weakness of the baby's abdominal wall where the umbilical cord joins it.
This weakness allows the abdominal contents, mainly the bowel and the liver to protrude outside the abdominal cavity.

Omphalocele. (Membranous Sac)

During fetal life the intestine develops inside the umbilical cord and then usually moves inside the abdomen at
10th week.
![Page 6: Congenital umblical hernia](https://reader034.vdocuments.mx/reader034/viewer/2022052508/559442c21a28abee2f8b461e/html5/thumbnails/6.jpg)
Occasionally, the intestine stays inside the umbilical cord and so develops outside the abdominal wall.
Because the contents are lying outside
the abdominal cavity often does not develop and remains small in size.

The presence of an omphalocele is often associated with other malformations.
suggesting that this anomaly is not a simple failure of umbilical ring closure.

Treatment It’s an emergency operation
as fluids and a lot of body heat are lost through the exposed intestines.
Type of operation depend on the type of the abdominal wall defect (major or minor ).

The goal of the radical cure is to introduce the viscera into an abdominal cavity
they have never occupied before and maintain them there without creating intrabdominalhypertension!!!?

where the surgeons move the intestines back inside the abdomen and then close up the muscles and skin.

Large exomphalos
a ‘staged repair’ as the exophalos is so large A mesh sack is placed over child’s intestine, which allows it to be contained and protected.

This sack is suspended above the child so that gravity moves the intestine back inside the abdomen.
The sack will be tightened regularly until all the intestine is inside the abdomen. This could take a number of days

Screening
An omphalocele is often detected through a detailed fetal
ultrasound.
![Page 26: Congenital umblical hernia](https://reader034.vdocuments.mx/reader034/viewer/2022052508/559442c21a28abee2f8b461e/html5/thumbnails/26.jpg)
Antenatal ultrasound demonstrates a large protroberance from
the anterior abdominal wall, consistent with an omphalocoele.
