omphalocele
Pronunciation: om-FAL-oh-seel
Congenital abdominal wall defect where intestines protrude through the umbilical cord base, covered by a membrane.
Full Definition
A congenital anomaly characterized by herniation of abdominal contents through a central abdominal wall defect at the base of the umbilical cord. The protruding organs are covered by a translucent peritoneal-amniotic membrane, distinguishing it from gastroschisis. Omphaloceles are frequently associated with other congenital anomalies and genetic syndromes, requiring comprehensive evaluation. Treatment involves staged surgical repair, with initial focus on protecting the membrane and managing associated conditions.
Usage
Usage note: Always distinguish from gastroschisis by noting membrane presence; document associated anomalies.
