Short answer · Medically reviewed summary · Last updated: 2026-05-08
Omphalocele is a congenital abdominal wall defect where an infant's intestines or other abdominal organs protrude outside the body through the navel, covered by a thin, sac-like membrane. Because omphalocele is a structural condition present at birth, it is typically diagnosed via prenatal ultrasound or immediately upon delivery, rather than being something an adult "develops" or self-assesses later in life. What are the primary signs of omphalocele? In a clinical setting, omphalocele is identified by the presence of a midline abdominal wall defect at the base of the umbilical cord.

Omphalocele is a congenital abdominal wall defect where an infant's intestines or other abdominal organs protrude outside the body through the navel, covered by a thin, sac-like membrane. Because omphalocele is a structural condition present at birth, it is typically diagnosed via prenatal ultrasound or immediately upon delivery, rather than being something an adult "develops" or self-assesses later in life.
What are the primary signs of omphalocele?
In a clinical setting, omphalocele is identified by the presence of a midline abdominal wall defect at the base of the umbilical cord. The organs are contained within a sac consisting of peritoneum and amnion. While omphalocele is often isolated, it is frequently associated with other genetic syndromes or chromosomal abnormalities, which is why clinical evaluation is essential.
How is omphalocele diagnosed?
Diagnosis is usually made during pregnancy through standard prenatal screenings. Key methods include:
- Prenatal Ultrasound: Often detects the defect during the second trimester.
- Maternal Serum Alpha-Fetoprotein (MSAFP) Screening: Elevated levels in the mother’s blood may indicate an abdominal wall defect.
- Fetal Echocardiogram: Performed to check for associated heart defects, which occur in approximately 20-50% of omphalocele cases.
- Genetic Testing: Amniocentesis or microarray analysis is often recommended to identify associated syndromes like Beckwith-Wiedemann syndrome or trisomies.
When should parents seek medical evaluation?
If a prenatal screening suggests an abdominal wall issue, parents should consult with a maternal-fetal medicine specialist and a pediatric surgeon. If a baby is born with an undiagnosed abdominal protrusion, this is a medical emergency requiring immediate surgical consultation to protect the sac and ensure the infant's stability. While omphalocele and gastroschisis are both abdominal wall defects, they are distinct conditions; omphalocele involves a sac, whereas gastroschisis does not, and they require different surgical approaches.
Next steps
- Consult with a board-certified pediatric surgeon or a neonatologist regarding surgical repair options.
- Request a referral to a genetic counselor to understand the underlying causes of the omphalocele.
- Connect with the DiseaseMaps.org community to share experiences with other families navigating this diagnosis.
- Create a birth plan that involves a specialized pediatric surgical center equipped to handle neonatal abdominal wall closures.
