Complex gastroschisis is "more dangerous for the baby,” Dr. Cara Buskmiller, fetal surgeon and maternal fetal medicine expert at Texas Children’s North Austin, tells PEOPLE. With the condition, the hole in the belly is tight, which can cause damage to the intestines and make the baby very sick at delivery, she explains. Complex gastroschesis is associated with a 10 to 15% risk of death and a 10% risk of a lifelong problem called short bowel syndrome, says Buskmiller.
