  • An omphalocele is a birth defect that causes the abdominal organs to herniate or protrude into the base of the fetus's umbilical cord.

  • When a giant omphalocele is present, the majority of the liver protrudes into the umbilical cord.

  • After birth, the exposed abdominal organs are returned to the abdominal cavity and the omphalocele is closed during a surgical procedure, called a primary repair.

    Omphalocele

  • The diagnosis of omphalocele is usually made by ultrasound, in many cases following an elevated second trimester maternal serum alpha-fetoprotein test.

  • An omphalocele is a type of abdominal wall defect in which the intestines, liver, and occasionally other organs remain outside of the abdomen in a sac because of a defect in the development of the muscles of the abdominal wall. The sac protrudes in the midline, through the umbilicus (navel).

    It is normal for the intestines to protrude from the abdomen, into the umbilical cord, until about the tenth week of pregnancy, after which they return to inside the fetal abdomen.

    The omphalocele can be mild, with only a small loop of intestines present outside the abdomen, or severe, containing most of the abdominal organs. In severe cases surgical treatment is made more difficult because the infant's abdomen is abnormally small because it had no need to expand to accommodate the developing organs.

    An omphalocele is often detected through AFP screening or a detailed fetal ultrasound. Genetic counseling and genetic testing such as amniocentesis is usually offered during the pregnancy. Some cases of omphalocele are due to an underlying genetic disorder.
