TL;DR: Gastroschisis is a congenital birth defect where an infant's intestines, and sometimes other organs, protrude through an opening in the abdominal wall beside the belly button. This condition requires specialized surgical intervention shortly after birth to protect the exposed organs and return them to the abdominal cavity. What exactly is Gastroschisis and how does it affect the body? Gastroschisis occurs when the abdominal wall fails to close completely during fetal development.
What is Gastroschisis
What is Gastroschisis? Plain-language, medically reviewed definition plus the lived reality told by patients.
TL;DR: Gastroschisis is a congenital birth defect where an infant's intestines, and sometimes other organs, protrude through an opening in the abdominal wall beside the belly button. This condition requires specialized surgical intervention shortly after birth to protect the exposed organs and return them to the abdominal cavity.
What exactly is Gastroschisis and how does it affect the body?
Gastroschisis occurs when the abdominal wall fails to close completely during fetal development. Unlike other abdominal wall defects, there is no protective sac covering the exposed organs, leaving them in direct contact with amniotic fluid. This exposure can lead to inflammation and irritation of the intestines. While Gastroschisis primarily affects the gastrointestinal system, the resulting inflammation may also impact the immune system, necessitating careful monitoring by neonatologists and pediatric surgeons.
How common is Gastroschisis?
Gastroschisis is considered a rare but increasingly recognized condition. According to the CDC, the prevalence has been rising globally, currently estimated at approximately 4 to 5 per 10,000 live births. Research indicates that younger maternal age is a significant risk factor, and the condition appears more frequently in infants born to mothers under the age of 20.
What differentiates Gastroschisis from similar conditions?
It is common to confuse Gastroschisis with omphalocele. Key clinical differences include:
- Location of the defect: In Gastroschisis, the opening is typically to the right of the umbilical cord, whereas an omphalocele occurs at the base of the umbilical cord.
- Protective covering: Gastroschisis lacks a protective membrane (sac) over the organs, while an omphalocele is covered by a thin sac.
- Associated anomalies: Infants with Gastroschisis rarely have other chromosomal abnormalities, whereas omphalocele is frequently associated with other genetic or systemic conditions.
How is Gastroschisis managed?
Treatment for Gastroschisis is highly specialized and begins immediately after delivery. For smaller defects, surgeons may perform a primary closure shortly after birth. In cases of larger defects, a "silo" or specialized pouch is used to gradually move the organs back into the abdomen over several days to avoid excessive pressure on the baby's developing internal systems.
