| | {{SK}} Congenital diaphragm hernia, Diaphragm hernia, Hernia through the diaphragm. |
| Historical perspective:
| |
|
| |
|
| In 1679, the first case of congenital diaphragmatic hernia was reported by Riverius.
| | ==[[Diaphragmatic hernia overview|Overview]]== |
| In 1888, the first procedure to repair congenital diaphragmatic hernia in an adult was done and in 1889, the first procedure on an infant was done.
| |
| In 1905, the first successful operation was done but the success rate was only about 60% in 1925.
| |
| In 1940, A set of diagnostic criteria for diaphragmatic hernia were suggested.
| |
| In 1950, the transthoracic approach was suggested instead of the transabdominal approach.

| |
| 90% of the congenital diaphragmatic hernias present in the neonatal period.

| Classification
| | ==[[Diaphragmatic hernia pathophysiology|Pathophysiology]]== |
|
| |
|
| Congenital diaphragmatic hernia can be classified into three types according to the site of herniation.
| | ==[[Diaphragmatic hernia causes|Causes]]== |
|
| |
|
| Posterolateral (Bochdalek) diaphragmatic hernia
| | ==[[Diaphragmatic hernia epidemiology and demographics|Epidemiology and Demographics]]== |
| It is the most common subtype.
| |
| Most commonly occurs on the left side and rarely occurs bilaterally.
| |
|
| |
|
| Anterior (Morgagni) diaphragmatic hernia
| | ==[[Diaphragmatic hernia risk factors|Risk Factors]]== |
| In anterior diaphragmatic hernia, the intestine bulges into the thorax through the anterior midline.
| |
| Most of the cases of anterior diaphragmatic hernia occur on the right side.
| |
|
| |
|
| Hiatal hernia
| | ==[[Diaphragmatic hernia screening|Screening]]== |
| The intestine finds its way to the thorax through the esophageal hiatus.
| |
| More common in the adults than in the neonates.

|
| Pathophysiology
| | == Diagnosis == |
|
| |
|
| The herniated viscera decrease the area needed by the lung to develop appropriately.

| According to the degree of herniation, the degree of pulmonary hypoplasia is determined.
| |
| The development of the pulmonary artery tree is halted too resulting in excessive masculinization of the arteries.
| |
| As most of the cases of diaphragmatic hernia is unilateral, the pulmonary hypoplasia is also usually unilateral, but it can be bilateral if the mediastinum is pushed by a massive unilateral hernia.
| |
| The abnormal alveolar development can lead to hypoxemia leading to pulmonary vasoconstriction which aggravates the condition.

|
| Natural history
| | ==Case Studies== |
| 90% of the cases of congenital diaphragmatic hernia presents in the neonatal period.
| |
| If left untreated, congenital diaphragmatic hernia can be fatal due to pulmonary hypoplasia and severe pulmonary hypertension.
| |
| Complications
| |
| GI complications
| |
| Pulmonary hypoplasia
| |
| Abnormal developmental rotation of the midgut
| |
| Midgut volvulus
| |
| Gastric volvulus
| |
| Cardiopulmonary complications
| |
| Pulmonary hypoplasia
| |
| Pulmonary artery hypertension
| |
| In severe cases, ventricular hypoplasia
| |
|
| |
|
| Prognosis
| | [[Diaphragmatic hernia case study one|Case #1]] |
| The prognosis is mainly dependent on the size of the defect and the degree of the herniation.
| |
| The presence or absence of liver herniation on fetal MRI is the most reliable prediction of the postnatal survival.
| |
| The estimation of fetal lung volume and lung area to head circumference is a useful indicator for the prognosis of the disease in the absence of liver herniation.
| |
| The mortality ranges from 25-60% of the cases.

| |
| | |
| | |
| ==Symptoms==
| |
| | |
| CDH most often presents in the neonatal period as:
| |
| | |
| Respiratory distress: The neonate may show cyanosis, tachycardia, lethargy, intolerance to feeding due to inadequate oxygenation.
| |
| Adrenal insufficiency: it is a common association with congenital diaphragmatic hernia.
