Overview & Description

Surgical repair of abdominal wall defects involves placing the abdominal organs back into the abdomen through the defect and repairing the defect if possible. If immediate replacement is not possible, a sterile pouch is created to protect the intestines while they are gradually pushed back into the abdomen over a period of time.

Immediately after delivery, the exposed organs are covered with warm, moist, sterile dressings. A nasogastric tube (NG tube) is inserted through the baby's nose or mouth into the stomach to keep the stomach empty. This prevents choking on or breathing stomach contents into the lungs (aspiration). The surgery is done as soon as the infant is stable.

While the baby is under general anesthesia, an incision is made to remove the sac membrane. The intestine is examined closely for signs of damage or additional birth defects. Damaged or defective portions are removed and the healthy edges are stitched together.

A tube may be inserted into the stomach (gastrostomy tube) and out through the skin.

If possible, the organs are replaced into the abdominal cavity and the incision closed. If the abdominal cavity is too small or the protruding organs are too swollen to allow the skin to be closed, a pouch will be made from a sheet of plastic (silo) to cover and protect the organs. Complete closure may be done over a few weeks.

Surgery may be necessary to repair the abdominal muscles at a later time.

The baby's abdominal cavity may be smaller than normal. Placing the abdominal organs into the abdomen increases the pressure within the abdominal cavity and can cause breathing difficulties. The infant may require the use of a ventilator for a few days or weeks until the swelling of the organs has decreased and the size of the abdomen has increased.
