Cogenital diaphragmatic hernia, can you give me more info?

Variable defect: When the diaphragm fails to finish forming, a hole is left between the chest ; abdomen ; bowel can slip into the lung cavity (herniate) before or just after birth(when baby starts to cry ; swallow air).If the lung forms well ; bowel slips later, there is a better chance of long term survival. Without room to form the lung on that side can fail.
