Omphaloceles are repaired with surgery, although not always immediately. A sac protects the abdominal contents and allows time for other more serious problems (such as heart defects) to be dealt with first, if necessary.
To fix an omphalocele, the sac is covered with a special man-made material, which is then stitched in place to form what is referred to as a “silo”. Slowly, as the baby grows over time, the abdominal contents are pushed into the abdomen.
When the omphalocele can comfortably fit within the abdominal cavity, the silo is removed and the abdomen is closed.
Sometimes the omphalocele is so large that it cannot be placed back inside the infant's abdomen. The skin around the omphalocele grows and eventually covers the omphalocele. The abdominal muscles and skin can be repaired when the child is older for a better cosmetic outcome.
