How is neonatal hiatal hernia usually formed?

Patient's question:

Newborn hiatal hernia. My colleague's child has been diagnosed with a congenital diaphragmatic hernia in newborns. What kind of disease is this? How can it be treated? I would like to ask for help. Is this condition very expensive to treat?

Doctor's answer:

Generally, at week 10 of pregnancy, when the midgut returns to the abdominal cavity through the base of the umbilical cord, due to the presence of the foramen of Morgagni, the intestines can pass through the foramen of Morgagni into the thoracic cavity, and even large defects such as the stomach, spleen, colon, and left lobe of the liver. They can enter the thoracic cavity together. Lung hypoplasia is closely related to diaphragmatic hernia, and the severity of lung hypoplasia is related to the timing and extent of the formation of visceral hernia. Diagnosis of diaphragmatic hernia in fetuses: Obstetric ultrasound specialists and fetal ultrasound specialists should check for other abnormalities and cardiac abnormalities, as well as chromosomal abnormalities, especially trisomy 18. Perinatal medicine specialists must discuss and decide whether to terminate the pregnancy, perform fetal surgery, or undergo postnatal surgery.
