omphalocele

 [om´fah-lo-sēl″]
protrusion, at birth, of part of the intestine through a defect in the abdominal wall at the umbilicus; see also umbilical hernia.
A large omphalocele with structure and contents of the hernial sac. From Betz et al., 1994.

om·phal·o·cele

(om'fal-ō-sēl, om'fă-lō-), [MIM*310980, MIM*164570]
Congenital herniation of viscera into the base of the umbilical cord, with a covering membranous sac of peritoneum-amnion. The umbilical cord is inserted into the sac here, in contradistinction to its attachment in gastroschisis.
See also: umbilical hernia.
[omphalo- + G. kēlē, hernia]

omphalocele

A congenital periumbilical defect in which loops of small intestine prolapse into a sac covered by peritoneum and amnion.

Mechanism
Caused by a failure of the intestine at 10 weeks of embryonic development (a time when the gut is normally outside the abdomen) to return to the abdominal cavity.

Neonatology A congenital periumbilical defect in which loops of small intestine prolapse into a sac covered by peritoneum and amnion

om·phal·o·cele

(om-fal'ŏ-sēl)
Congenital herniation of viscera into the base of the umbilical cord, with a covering membranous sac of peritoneum-amnion.

omphalocele

Herniation of some of the abdominal contents into the umbilical cord.

Omphalocele

A congenital hernia in which a small portion of the fetal abdominal contents, covered by a membrane sac, protrudes into the base of the umbilical cord.

For instance, gastroschisis and omphalocele both have the same ICD-9-CM code of 756.79 and yet they are distinct birth defects.
A thin membrane that keeps the organs intact usually covers the omphalocele. While the condition can range in size and severity, the intestines, and sometimes the liver and spleen, protrude outside the baby's body.
The NIH study associated anencephaly with Paxil and its generic forms and omphalocele with Zoloft and its generic equivalents.
There also were small but significant associations with anencephaly (based on 9 exposed neonates), craniosynostosis (based on 24 exposed neonates), and omphalocele (based on 11 exposed neonates).

(1,4,8) While 40% to 50% of trisomy 21 fetuses have congenital heart defects, only 20% to 30% have other major structural malformations such as duodenal atresia, hydrops, hydrothorax and omphalocele. (2-4,6-10) With the majority of births occurring to women who are otherwise considered low risk and because many Down syndrome fetuses do not present with major abnormalities, it is crucial that technologists are aware of the associated sonographic markers.
Although the number of these infants is not large, many of the defects, such as a patient with an omphalocele or gastroschesis, place the infant in jeopardy due to massive evaporative losses.
In the case of some anomalies, such as omphalocele or gastroschises, foreknowledge of the abnormality assists in planning a mode of delivery and prompt intervention in the care of the neonate.[10]
spigelian, gastroschisis and omphalocele were not seen during our study period.
Frequently associated malformations, for example, are cardiac abnormalities and omphalocele [6].
The morphology scan demonstrated a small omphalocele but otherwise no significant structural defects and estimated foetal weight was noted to be within the normal range.
