Empyema Surgery · Pleural Infection · London
You’ve had the antibiotics. You’ve had the drain. And you’re still not better.
Empyema — infected fluid in the space around the lung — often doesn’t resolve with antibiotics and a chest drain alone. If you or a family member are still in hospital, still febrile, still struggling to breathe weeks after a chest infection or pneumonia, this may be why. Delayed or inadequate treatment allows empyema to progress through stages that become significantly harder to treat. Early surgical drainage changes outcomes. Urgent cases are seen the same day.
🚨 If you have suspected empyema — act quickly
Empyema that is not adequately drained progresses from a freely drainable fluid to a thick, loculated, organised infection that is significantly harder to treat. Early surgical intervention produces better outcomes than delayed treatment. Call 020 7459 4367 or go to A&E if you have fever, breathlessness, chest pain, and a history of recent pneumonia or chest infection.
Understanding empyema
The three stages — and why stage matters
Empyema progresses in three stages. The appropriate treatment depends critically on which stage the infection has reached — ideally assessed by CT scan and pleural fluid sampling.
Stage 1 — Exudative (free-flowing)
Thin, freely flowing infected pleural fluid. The pleural membranes are not yet thickened. Treated effectively with antibiotics and chest drain insertion alone in many cases. CT typically shows simple effusion without loculations.
Stage 2 — Fibrinopurulent (loculated)
Thickened, sticky fluid with fibrin deposits forming loculations (septations) that prevent simple drainage. Antibiotics alone insufficient. VATS surgical debridement is the treatment of choice — breaking down loculations and washing out infected material.
Stage 3 — Organised (trapped lung)
The lung is encased in a thick fibrous rind (pleural peel) that prevents it from expanding. Treatment requires decortication — surgical removal of the fibrous peel to free the trapped lung. VATS decortication if technically feasible; open thoracotomy if extensive.
Treatment approaches
From antibiotics to VATS — choosing the right treatment
Antibiotics + chest drain
For early, free-flowing empyema. Broad-spectrum intravenous antibiotics, chest drain placement under ultrasound guidance. Intrapleural fibrinolytics (tPA/DNase) may be used to break up early loculations non-surgically.
VATS debridement
Video-assisted thoracoscopic surgery to break down all fibrin loculations, drain purulent material, irrigate the pleural space, and place a well-positioned drain. Best outcomes for stage 2 empyema — shorter hospital stay than prolonged drain management and better lung re-expansion.
Decortication
Surgical removal of the fibrous pleural peel encasing the lung. VATS decortication where feasible; open thoracotomy for extensive or very thick peels. Allows the trapped lung to re-expand. Most demanding empyema operation — recovery longer but results can be excellent.
Stage 1 empyema can often be managed without surgery — antibiotics, chest drain, and intrapleural fibrinolytics (tPA/DNase) are effective for simple, early empyema. For stage 2 (loculated) empyema, the evidence strongly favours early VATS over prolonged non-surgical management — surgical patients have shorter hospital stays, better outcomes, and less risk of progressing to stage 3. Delaying surgery in stage 2 empyema in the hope that antibiotics and drains will suffice is a common pattern that often results in a worse outcome. Stage 3 organised empyema requires surgery.
If the lung hasn’t re-expanded after drain placement and antibiotics, this suggests either ongoing loculations preventing drainage (stage 2) or the beginning of a fibrous rind forming (early stage 3). This is exactly the situation that benefits from early VATS — before the fibrous peel matures and makes decortication more difficult. A CT scan to assess the current stage is the priority.
For VATS debridement of stage 2 empyema, the typical hospital stay is 4–7 days. For decortication of stage 3, 5–10 days depending on the extent of pleural involvement and how well the lung re-expands. Full recovery is typically 6–10 weeks. This is significantly shorter than the prolonged drain-and-antibiotics pathway that many stage 2 patients end up on.
For stage 1 and 2 empyema treated appropriately, lung function typically returns to normal or near-normal after recovery. For stage 3 with significant lung entrapment, recovery of lung function depends on how long the lung was trapped and how successfully decortication freed it. Most patients see significant improvement over 3–6 months as the liberated lung re-expands. Some residual impairment may persist if decortication was delayed.
Empyema requires prompt treatment.
Early surgical intervention produces significantly better outcomes than delayed management. Urgent cases are seen the same day.
