In simple words: Exomphalos (or omphalocele) is a birth defect where a baby's intestines or other organs stick out through the belly button.The organs are usually covered by a thin sac.

Q79.2, Exomphalos (Omphalocele), is an ICD-10-CM code representing a congenital anomaly characterized by herniation of abdominal viscera through a defect in the abdominal wall at the umbilicus.The herniated organs are typically covered by a thin membrane composed of peritoneum and amnion.This differs from gastroschisis, where the abdominal wall defect is lateral to the umbilicus, and the herniated organs lack membrane covering.Prenatal diagnosis is possible but postnatal confirmation is crucial to differentiate from similar conditions.The size and content of the herniation can vary significantly.

Example 1: A newborn presents with a visible protrusion of abdominal organs at the umbilicus, covered by a translucent membrane.Prenatal ultrasound had suggested a possible omphalocele., A pregnant woman undergoes an ultrasound which reveals a large omphalocele in the fetus.Genetic counseling is recommended., A premature infant is born with a small omphalocele which is surgically repaired within the first few days of life.

Detailed prenatal ultrasound findings (if available), complete physical examination of the newborn, description of the size and contents of the herniation, surgical reports, and postnatal imaging if applicable.
