When the diaphram 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 lomg term survival. Without room to form the lung on that side can fail.Rapid recognition & suportiive care is a must.
