In case of CDH, the incomplete development of a part of the diaphragm allows abdominal viscera to herniate into thorax cavity during fetal development and impaired lung and heart development.

After birth, CDH patients who survived thanks to an active reanimation management undergo diaphragmatic repair. In case of large defect, a patch is needed to complete diaphragmatic closure. Thanks to primary cell culture from foreskin, peritoneal epithelium or cremaster dedicated to incineration investigators want to analyse biological integration of actually used prothesis and others innovations.

Inclusion Criteria:

Exclusion Criteria:
