    Definition

    Abdominal wall defects are birth (congenital) defects that allow the stomach or intestines to protrude.



    Description
    Many unexpected and fascinating events occur during the development of a fetus inside the womb. The stomach and intestines begin development outside the baby's abdomen and only later does the abdominal wall enclose them. Occasionally, either the umbilical opening is too large, or it develops improperly, allowing the bowels or stomach to remain outside or squeeze through the abdominal wall.

    Causes and Symptoms
    There are many causes for birth defects that still remain unclear. Presently, the cause(s) of abdominal wall defects is unknown, and any symptoms the mother may have to indicate that the defects are present in the fetus are nondescript.

    Diagnosis
    At birth, the problem is obvious, because the base of the umbilical cord at the navel will bulge or, in worse cases, contain viscera (internal organs). Before birth, an ultrasound examination may detect the problem. It is always necessary in children with one birth defect to look for others, because birth defects are usually multiple.

    Treatment
    Abdominal wall defects are effectively treated with surgical repair. Unless there are accompanying anomalies, the surgical procedure is not overly complicated. The organs are normal, just misplaced. However, if the defect is large, it may be difficult to fit all the viscera into the small abdominal cavity.

    Prognosis
    If there are no other defects, the prognosis after surgical repair of this condition is relatively good. However, 10% of those with more severe or additional abnormalities die from it. The organs themselves are fully functional; the difficulty lies in fitting them inside the abdomen. The condition is, in fact, a hernia requiring only replacement and strengthening of the passageway through which it occurred. After surgery, increased pressure in the stretched abdomen can compromise the function of the organs inside.

    Prevention
    Some, but by no means all, birth defects are preventable by early and attentive prenatal care, good nutrition, and supplemental vitamins, diligent avoidance of all unnecessary drugs and chemicals-especially tobacco-and other elements of a healthy lifestyle.

    Key Terms
    Hernia
    Movement of a structure into a place it does not belong.

    Umbilical
    Referring to the opening in the abdominal wall where the blood vessels from the placenta enter.

    Viscera
    Any of the body's organs located in the chest or abdomen.
