The principles of surgical repair are to return the abdominal contents to the abdominal cavity and repair the diaphragmatic defect. It may be possible to repair the defect by simply suturing the edges together. However, if the defect is large a patch repair may be undertaken using prosthetic material.

The main GI consequence appears to be gastroesophageal reflux, seen in up to 62% of cases.48
