Why does the diaphragmatic hernia in the abdominal organs herniate into left chest cavity?

Usually on the Left. Congenital diaphragmatic hernias occur on the left 85% of the time and are posterior (bochdalek hernia), most the rest are located on the right posteriorly. About 2% occur anteriorly in the middle (morgagni hernia). Adults can get hiatal hernias on the left, because that is where the esophagus passes through the diaphragm to reach the stomach. Trauma and surgery can cause diaphragmatic hernias too.

Can you tell me, why in diaphragmatic hernia the abdominal organs herniate into left chest cavity?

Diaphragmatic hernia. Diaphragmatic hernias most commonly affect the left side of the diaphragm; that muscle between the abdominal cavity and the chest. A hernia is a hole or defect in the muscle. In the case of a diaphragmatic hernia, this hole creates an unusual connection between the abdomen and chest. The normally higher pressure within the abdomen will push abdominal organs from the abdomen up into the chest. Read more...
More vulnerable side. When there is a developmental defect in the breathing muscle, it is more likely to effect the left side toward the back. The pressure of the womb can cause the intestine to migrate up into the chest cavity during pregnancy and interfere with lung formation.If the defect is small, babies swallowing air at birth creates extra pressure and may push it up later.

When a diaphragmatic hernia occurs, some of the abdominal contents, such as liver, intestines, and stomach come into chest. How then does baby breathe when born?

If severe, baby dies. That's why babies with severe defects in their diaphragms generally die in the neonatal period unless promptly and expertly treated (and with good luck). Extreme cases even merit in utero surgery, although more recent minimally invasive (tracheal balloon occluson) technique may have wider applications to less severe cases. http://www.youtube.com/watch?v=lwzeugpinvu&feature=youtu.be.

With difficulty. Babies with diaphragmatic hernia (cdh) may have severe pulmonary dysplasia (lung malformation). This may leave them unable to oxygenate and expel carbon dioxide. Oftentimes these bables will need to be on a ventilator until their pulmonary hypertension resolves and the cdh is repaired. Read more...
Diaphragmatic Hernia. Newborn infants with large diaphragmatic hernias often have the under-development of the lung on that same side. Often these newborns do not breath very well at birth, necessitating the placement of a breathing tube and the use of temporary mechanical ventilation. Read more...
Depends. If the infant went through a complete pregnancy before the herniation, initial stabilization & repair can have a great outcome (normal lung development & few lung problems after infancy) . If herniation occurred during pregnancy, outcome depends on how bad it impaired lung development.Early recognition at birth with placement of a stomach tube & breathing tube may give baby a chance.

When a diaphragmatic hernia occurs, some of the abdominal contents push up, right?

Usually. However if the hernia is covered by the liver, the liver is big enough to prevent things from going into the chest. Read more...
Yes. A diaphragmatic hernia is a hole in the diaphragm through which abdominal contents herniate in to the chest. Most common is a hiatal hernia, which involves the stomach. Other types include congenital holes, and are called Bochdalek and Morgagni hernias. You could also have a tear caused by trauma. Only treatment is surgical repair. Hope this helps! Read more...

Which organs get affected when a diaphragmatic hernia occurs?

Lungs mainly. The main lethality of congenital diaphragmatic hernia lies with its effect on the fetal lung development. As much of the fetal abdominal contents are inside the fetal chest during lung development, there is a great risk the lung become hypoplastic and dysfunctional. This means that without intervention many of the affected babies die at birth from respiratory failure. Fetal therapy options increas. Read more...
