Congenital Diaphragmatic Hernia

Congenital Diaphragmatic Hernia
A congenital hernia of the diaphragm (CDH) develops as a result of a primary developmental diaphragmatic defect that allows proximal herniation of abdominal organs into the thoracic cavity. Approximately 75% of the time, the diaphragmatic defect is posterolateral (Bochdalek hernia) and typically on the left side, whereas 25% are anteromedial (Morgagni hernia). 

Congenital Diaphragmatic Hernia

CDH may present as respiratory disease due to extrinsic compression of abdominal organs on the developing lungs with pulmonary hypoplasia. Association of CDH with multiple well­defined genetic syndromes, chromosomal abnormalities, or other congenital anomalies strongly suggests a genetic predisposition. Although the stomach is the most common abdominal organ to herniate into the chest, the small and large bowel, liver, spleen, and pancreas may also herniate. Diagnosis is typically made with prenatal ultrasound or is suspected at birth due to pulmonary compromise. In some patients, the presentation may be much later in life, including adulthood. Symptoms in later life include postprandial upper abdominal and chest pain or acute symptoms of incarceration. Diagnosis is best made through computed tomography of the chest and/or barium studies. The only effective treatment is surgery; visceral organs are reduced into the abdomen, and diaphragmatic defects are either oversewn or patched, depending on the size of the defect.
