Omphalocele

Omphalocele is a birth defect where a baby's intestines or other abdominal organs stick out of the belly button area through an opening in the abdominal wall. This happens because the muscles in the abdomen do not close properly during fetal development. The exposed organs are covered by a thin, transparent sac made of membrane. This condition affects the digestive system and can cause problems with organ function and protection. Babies with omphalocele often need specialized medical care right after birth to protect the organs and support normal growth. It is a serious condition that requires careful monitoring and treatment. The size of the defect and the organs involved can vary, influencing the severity of health effects.

Omphalocele is a congenital abdominal wall defect characterized by herniation of abdominal viscera into the base of the umbilical cord, covered by a peritoneal sac. It results from failure of the lateral body folds to fuse during embryonic development, typically between the 6th and 10th weeks of gestation. The defect involves a midline defect at the umbilical ring, allowing protrusion of intestines, liver, or other organs. It is often associated with other congenital anomalies and chromosomal abnormalities such as trisomies 13, 18, and Beckwith-Wiedemann syndrome. The presence of the protective sac distinguishes it from gastroschisis, which lacks a covering membrane. Clinically, it presents as a visible abdominal wall mass at birth and carries risks of infection, organ damage, and respiratory compromise depending on the size of the defect and associated anomalies.
