Pleural Diseases (Effusion & Pneumothorax)
Fluid or air around the lung needs a cause, not just a drain — thoracoscopy answers it in one sitting.
The pleura is the thin double membrane between your lung and chest wall. When fluid collects in that space it is a pleural effusion; when air collects it is a pneumothorax; when infected fluid becomes thick and loculated it is an empyema. All three present with breathlessness and chest discomfort, and all three have very different causes.
Draining the fluid relieves symptoms but does not answer the question that matters — why it collected. Tuberculosis, infection, cancer, heart failure, kidney or liver disease and autoimmune conditions all produce effusions. Medical thoracoscopy lets us look directly at the pleural surface and take targeted biopsies, giving a definite diagnosis in the great majority of cases where fluid analysis alone was inconclusive.
Symptoms we look out for
- Breathlessness that worsens when lying flat or over a few days
- Sharp, one-sided chest pain, worse on deep breathing or coughing
- Dry cough with a feeling of heaviness on one side of the chest
- Fever, night sweats or weight loss with the above (infection or tuberculosis)
- Sudden severe breathlessness in a tall, thin young adult (spontaneous pneumothorax)
Diagnostics we offer
Medical thoracoscopy & pleural biopsy
Direct visual inspection of the pleura with targeted biopsy — the highest-yield test for undiagnosed effusion, and it allows pleurodesis in the same sitting.
Pulmonary Function Test (PFT)
Documents restriction from trapped lung or pleural thickening, and tracks recovery after drainage.
Our treatment approach
- Bedside ultrasound to confirm and safely localise fluid or air before any procedure
- Diagnostic pleural tap with biochemistry, cell count, cytology, ADA and culture including for tuberculosis
- Therapeutic drainage or intercostal drain for large effusions, empyema and pneumothorax
- Medical thoracoscopy with pleural biopsy when the cause remains unclear
- Talc pleurodesis or indwelling catheter for recurrent malignant effusion
- Cause-directed treatment — anti-tuberculous therapy, antibiotics, oncology referral or heart-failure management
Common questions
The fluid was drained but came back — why?
Because drainage treats the symptom, not the cause. Recurrence means the underlying process is still active — tuberculosis, infection, malignancy or heart failure. That is precisely when thoracoscopy with biopsy is worthwhile rather than another blind tap.
Is thoracoscopy major surgery?
No. Medical thoracoscopy is done under local anaesthesia with sedation through a small single port, usually with a short hospital stay — not a thoracotomy.
Can pleural effusion be tuberculosis without a cough?
Yes, frequently. Tuberculous pleural effusion often presents with fever, chest pain and breathlessness and little or no cough. It is the commonest cause of a lymphocytic effusion in India.
