Very rarely, the abdominal wall will close partially or completely around the intestines while the baby is still in the womb. This is very dangerous as it can cause a significant amount of bowel to be lost, and can be life-altering or even fatal.28This is called vanishing or closing gastroschisis. While there is no definitive way to predict this, dilated loops of intra-abdominal bowel and decreased blood flow to the exposed intestines can be an indicator.29
