gastroschisis
Pronunciation: gas-TROS-ki-sis
Congenital abdominal wall defect with intestinal herniation beside the umbilicus.
Full Definition
A congenital abdominal wall defect characterized by herniation of intestinal contents through a full-thickness defect in the abdominal wall, typically located to the right of the umbilical cord insertion. Unlike omphalocele, the herniated bowel is not covered by a protective membrane and is directly exposed to amniotic fluid, leading to inflammatory changes and potential complications. The condition requires immediate surgical intervention after birth, often involving staged closure techniques. Associated anomalies are less common than with omphalocele, but intestinal complications such as atresia may occur.
Usage
Usage note: Greek origin meaning 'belly split'; often confused with omphalocele but lacks covering membrane.
