Background:A diaphragmatic hernia is a serious medical condition in which an abnormal opening or defect in the diaphragm allows organs from the abdomen, such as the stomach or intestines, to move into the chest cavity. It can be congenital or acquired. Congenital diaphragmatic hernias are rare and usually occur on the left side (80%) of the diaphragm. Acquired diaphragmatic hernia usually occurs following trauma.
