Congenital Lobar Emphysema
Learn symptoms, causes, management of congenital lobar emphysema, and when to contact a paediatric surgeon in Singapore.
What Is Congenital Lobar Emphysema?
Congenital lobar emphysema (CLE) is a rare lung condition that babies are born with, where one section (lobe) of the lung becomes overinflated, resembling a balloon, and takes up extra space in the chest.
The overinflated lobe traps air inside; air enters but has trouble escaping. As more and more air gets trapped, the lobe expands and can compress the rest of the lung on the same side and even push on the other lung. This makes it harder for your baby to breathe properly.
While the name includes "emphysema," this is different from the smoking-related emphysema that adults get. Congenital emphysema is a birth defect affecting lung development, not damage from environmental factors.
Most cases of congenital lobar emphysema show symptoms in the first few months of life, often causing respiratory distress in newborns. Some milder cases may not be noticed until later in infancy or early childhood. Severe cases may require congenital emphysema surgery to remove the affected lobe.
Common Symptoms of Congenital Lobar Emphysema
Symptoms depend on the severity of the hyperinflation and the pressure on surrounding tissue.
In Newborns and Young Infants
Most babies with congenital lobar emphysema develop respiratory distress within the first few days to months of life:
-
Trouble breathing with fast, laboured breaths
-
Wheezing or noisy breathing sounds
-
Grunting with each breath
-
Blue or purple skin colour (cyanosis) from low oxygen levels
-
Chest looks uneven - one side may appear larger or bulge out
-
Using extra muscles to breathe - you can see the ribs pulling in with each breath
-
Flaring nostrils as the baby struggles to get air
-
Poor weight gain due to feeding difficulties
-
Rapid heart rate
In Older Infants and Children
Milder cases may not show symptoms until later:
-
Recurring respiratory infections (pneumonia, bronchitis)
-
Persistent wheezing
-
Chronic cough
-
Getting tired easily during activity
-
Shortness of breath with exertion
-
Chest pain occasionally
When to Seek Care
Contact us immediately if your newborn has breathing difficulties, blue skin colour, trouble feeding due to breathing problems, or if your older child has recurrent lung infections or persistent breathing issues. We'll evaluate whether CLE lobectomy paediatric surgery is needed for treatment.
What Causes Congenital Lobar Emphysema?
Congenital lobar emphysema develops during pregnancy when the lungs are forming. It represents an abnormality in the development of the airways or lung tissue.
The exact cause of congenital lobar emphysema isn't always clear, but several factors can lead to a hyperinflated lung lobe.
Abnormal Bronchial Cartilage
The most common cause is defective or underdeveloped cartilage in the bronchus (the tube leading to that lobe). Cartilage provides structure to keep the airways open. When cartilage is weak or absent, the airway can collapse during breathing. Air enters when the baby breathes in, but the airway collapses during exhalation, trapping air inside. Over time, more and more air accumulates, causing progressive overinflation.
Bronchial Obstruction
Something blocking or narrowing the airway to the affected lobe can cause air trapping. This might include mucus plugs present from birth, abnormal tissue or masses pressing on the bronchus, blood vessels compressing the airway, or congenital narrowing (stenosis) of the bronchus.
Abnormal Lung Tissue
Sometimes the lung tissue itself develops abnormally with too many or oversized air spaces (alveoli), abnormal elastic tissue that can't deflate properly, or defective lung structure that allows overinflation.
Important Points for Parents to Note
-
You could not have done anything to cause this during pregnancy
-
Congenital lobar emphysema is not a preventable condition; it happens by chance during lung development
-
It is not an inheritable condition
-
It's not related to maternal smoking or other environmental factors
Consequences of Untreated Congenital Lobar Emphysema
Congenital lobar emphysema is not a condition that improves on its own. Without treatment, the hyperinflated lung lobe continues to expand, causing serious complications.
Progressive Respiratory Distress
The most immediate danger is worsening breathing problems. As the affected lobe continues to overinflate:
-
It compresses the rest of the lung on the same side, preventing it from expanding
-
It pushes on the other lung, reducing its ability to function
-
Your child has less and less functional lung tissue available for breathing
Without congenital emphysema surgery, this can lead to severe respiratory failure.
Lung Infections
When compressed by the hyperinflated lobe, normal lung tissue cannot ventilate properly, making infections more likely. Children with untreated congenital lobar emphysema often develop recurrent pneumonia, persistent bronchitis, difficulty clearing infections even with antibiotics, and progressive lung damage from repeated infections.
Pneumothorax (Collapsed Lung)
The overinflated lobe can rupture, causing air to leak into the chest cavity. This causes the lung to collapse (pneumothorax) - a medical emergency requiring immediate treatment. Signs include sudden, severe chest pain, severe breathing difficulty, and rapid worsening of symptoms.
Heart Problems
Severe untreated congenital lobar emphysema can affect the heart. The overinflated lobe presses on the heart and major blood vessels, shifting them to the opposite side of the chest (mediastinal shift). This can cause abnormal heart function, decreased blood flow, and increased pressure on the heart. In severe cases, this can lead to heart failure.
Other Complications
Babies with respiratory distress from CLE often can't feed well because breathing is so difficult. This leads to malnutrition, poor weight gain, developmental delays, along with weakness and fatigue.
Children who survive without immediate treatment often have chronic breathing difficulties, permanent lung damage, reduced exercise capacity, recurrent hospitalisations, and poor quality of life later on.
However, with proper diagnosis and timely CLE lobectomy paediatric surgery, most children recover completely and go on to have normal lung function and active lives.
How to Treat Congenital Lobar Emphysema
Treatment for congenital lobar emphysema depends on the severity of symptoms. At The Little Surgery, Dr. Ong Lin Yin provides comprehensive care from evaluation to supportive management, and expert paediatric CLE lobectomy procedures when necessary.
Evaluation and Diagnosis
Dr. Ong will examine your child, listening to the lungs (decreased breath sounds on the affected side), checking breathing effort and oxygen levels, observing chest shape, and assessing overall health.
Proper diagnosis requires detailed imaging like X-rays, CT, MRI, and ultrasound scans to identify which lobe is affected, the degree of hyperinflation and compression, and any masses or abnormalities. Echocardiogram (ultrasound of the heart) and bronchoscopy (looking into the airways with a camera) may be carried out if there are concerns. These tests help us plan surgical approaches for CLE lobectomy paediatric surgery.
Initial Management and Stabilisation
When babies present with respiratory distress, initial treatment focuses on stabilising breathing, using oxygen therapy or respiratory support (continuous positive airway pressure or mechanical ventilation) if respiratory distress is severe.
Close monitoring in the hospital ensures your baby stays stable and allows a swift response if breathing worsens. If infection is present, antibiotics are given to clear it before surgery when possible.
Observation for Mild Cases
Very mild cases of congenital lobar emphysema that cause minimal or no symptoms may be monitored carefully without immediate surgery. This involves regular follow-up visits and X-rays/CT scans to monitor for worsening.
However, most paediatric experts recommend CLE lobectomy paediatric surgery even for mild cases, as the condition tends to worsen over time, and surgery before symptoms develop is safer and easier.
Surgical Treatment - Paediatric CLE Lobectomy
Surgery is the definitive treatment for symptomatic congenital lobar emphysema. The standard procedure is the removal of the affected lobe (lobectomy).
CLE lobectomy is needed eventually, because medical treatments (oxygen, medications) don't fix the underlying problem, and the hyperinflated lobe won't deflate on its own. Removing the bad lobe will allow the remaining healthy lung to expand and function normally as soon as possible.
For babies with severe respiratory distress, surgery may be needed urgently, sometimes within the first days or weeks of life. For babies with moderate symptoms, surgery is typically done in the first few months once the baby is stable. For milder cases, surgery may be planned for when the baby is a bit older (3-6 months) but before complications develop.
Paediatric CLE lobectomy is performed under general anaesthesia, so your child is asleep and comfortable. The surgery typically takes 2-4 hours.
In some older children with less severe disease, thoracoscopic (minimally invasive) approaches may be possible using small incisions and a camera. However, most cases of congenital lobar emphysema in babies require traditional open surgery for safety.
Recovery
Children typically stay in the hospital for 5-10 days after congenital emphysema surgery, with pain management to keep them comfortable. A chest tube drains fluid and air as the remaining lung expands, and is removed after 3-5 days when drainage decreases.
Once your child is eating well, breathing comfortably without oxygen, and the incision is healing, they can return home. You'll receive instructions for wound care, activity restrictions, when to call the doctor, and follow-up appointments.
After a successful CLE lobectomy paediatric surgery, most children do wonderfully. The remaining healthy lung tissue grows and compensates completely, and children can participate in all activities without restrictions.
