What Are Lung Bullae?

​

Lung bullae are abnormally large air-filled spaces within the lung tissue, usually resulting from the destruction of alveolar walls. Over time, these damaged air sacs merge to form a larger air-filled cavity known as a bulla.

Small bullae may cause no symptoms. However, as they enlarge, they can compress healthy lung tissue and reduce breathing efficiency.

​

What Causes Lung Bullae?

The most common causes include:

• Smoking (the leading cause)

• Chronic Obstructive Pulmonary Disease (COPD)

• Emphysema

• Genetic factors (such as Alpha-1 Antitrypsin deficiency)

• Previous lung infections or trauma

• In some cases, they may occur in otherwise healthy individuals without a clear cause

​

What Are the Symptoms?

Symptoms vary depending on the size and effect of the bulla:

• Shortness of breath (especially on exertion)

• Chest pain or pressure

• Reduced exercise tolerance

• Chronic cough (in some cases)

• Pneumothorax (rupture of the bulla causing air leakage around the lung)

⚠️ Some patients have no symptoms, and the condition is discovered incidentally.

​

How Is It Diagnosed?

Diagnosis is based on:

• Medical history and clinical examination

• Chest X-ray

• CT scan (most important test) to determine:

  • Size of the bulla

  • Location

  • Impact on surrounding lung tissue

• Pulmonary Function Tests (PFTs)

​

When Is Surgery Needed?

Not all patients require surgery.

Surgical treatment is considered in the following cases:

• Significant shortness of breath affecting daily life

• Large bulla compressing healthy lung tissue

• Recurrent pneumothorax

• Persistent chest pain related to the bulla

• Failure of conservative treatment

​

What Is the Surgical Treatment?

Bullectomy (Removal of the Bulla)

This is a surgical procedure in which the bulla is removed while preserving as much healthy lung tissue as possible, allowing the lung to expand more effectively and improving breathing.

​

How Is the Surgery Performed?

1. VATS (Video-Assisted Thoracoscopic Surgery)

• Most commonly used technique

• Small incisions

• Less pain

• Faster recovery

2. Open Surgery

• Used in complex cases

• When there are severe adhesions or multiple bullae

​

What Happens During Surgery?

• Removal of the bulla using specialized surgical staplers

• In some cases, pleurodesis is performed to prevent recurrence of pneumothorax

• Placement of a temporary chest tube to drain air after surgery

​

Benefits of Surgery

• Improved breathing

• Reduced pressure on healthy lung tissue

• Better physical activity tolerance

• Reduced risk of recurrent pneumothorax

​

Possible Risks

As with any surgery, there are potential risks:

• Air leak after surgery (usually temporary)

• Pain or infection

• Bleeding (rare)

• Recurrence of bullae in some cases

• Complications related to underlying lung function

​

What Happens After Surgery?

• Hospital stay: a few days depending on recovery

• Breathing exercises are essential

• Early mobilization (walking) is highly recommended

• Regular follow-up

🚫 Smoking cessation is critical to prevent recurrence

​

When Should You See a Thoracic Surgeon?

You should seek evaluation if you have:

• Unexplained shortness of breath

• A large bulla detected on imaging

• History of pneumothorax

• Symptoms affecting quality of life

​

Summary

Lung bullae may be a mild condition or a significant problem affecting breathing. The decision for surgical treatment depends on careful evaluation of each case, aiming to improve quality of life and prevent complications.

​

Frequently Asked Questions (FAQ)

​

Do all lung bullae require surgery?

No. Many cases only require monitoring if there are no symptoms.

​

Is the surgery dangerous?

The procedure is generally safe, especially when performed using minimally invasive techniques by an experienced thoracic surgeon. As with any surgery, risks are explained beforehand.

​

How long does the surgery take?

Typically 1–2 hours, depending on the case.

​

How long is the hospital stay?

Usually 2–5 days, depending on recovery and presence of air leaks.

​

When can I return to normal life?

• Light activity: within a few days

• Work: within 1–2 weeks

• Full activity: within 3–4 weeks

​

Can the bulla come back after surgery?

Yes, in some cases—especially if smoking continues or in chronic lung disease.

​

Will breathing improve after surgery?

Yes, significantly in properly selected patients, especially when the bulla compresses healthy lung tissue.

​

When should I seek urgent medical care?

• Sudden shortness of breath

• Severe chest pain

• Sudden worsening cough

• Symptoms of pneumothorax
