Wedge resection of the lung (Wedge resection of lung (sublobar resection))
An operation to remove a small wedge-shaped piece of lung, often to take out or diagnose a nodule while keeping as much healthy lung as possible.

In short
- A wedge resection removes a small piece of lung to take out or diagnose a nodule while saving as much healthy lung as possible.
- It is often chosen when a lobectomy would remove too much lung, or to remove a spread from another cancer, or to get a diagnosis — but it may give narrower margins and less lymph-gland sampling than a lobectomy.
- It is usually keyhole surgery with a shorter recovery than a lobectomy, though it is still a chest operation.
- Whether a wedge is enough for a cancer is a careful MDT decision, balancing complete removal against preserving lung function.

What is a wedge resection of the lung?
A wedge resection removes a small, wedge-shaped piece of lung containing a nodule or area of concern, rather than a whole lobe. Because it takes out less tissue than a lobectomy, it preserves more lung function.
It is used to remove or diagnose a lung nodule, to take out a small early cancer in people who cannot safely lose a whole lobe, to remove a spread (metastasis) from another cancer, or to obtain tissue for diagnosis when other tests have not given an answer. It is usually done by keyhole surgery (VATS), but sometimes open.
Unlike a lobectomy or segmentectomy, a wedge resection does not follow the lung's anatomical boundaries, so it does not always allow the same thorough sampling of lymph glands or the same wide margins. For a cancer that could be removed more completely, a wedge may not be the best operation. Your team weighs up clearing the disease against preserving lung tissue.
Types & techniques
There isn't one single operation. The right approach depends on you — which is something to discuss with your surgeon.
Wedge resection compared with lobectomy
| Feature | Wedge resection | Lobectomy |
|---|---|---|
| Tissue removed | Small wedge | A whole lobe |
| Lung function kept | More preserved | Less preserved |
| Margins / lymph nodes | Narrower; less sampling | Wider; fuller staging |
| Typical recovery | Often quicker | Several weeks to months |
For a fit person with an early cancer, a lobectomy may give a more complete operation; a wedge may be chosen to preserve lung or to diagnose. Your MDT advises which is right for you.
Preparing for your surgery
- Ask why a wedge is being recommended rather than a lobectomy or segmentectomy, and what this means for clearing a cancer.
- Expect tests of your heart and lung function to confirm you can tolerate surgery.
- Tell the team about all medicines, especially blood thinners, and ask which to pause and when.
- Stop smoking as early as possible to lower the risk of breathing and wound problems.
- Ask whether the nodule may need marking before surgery so it can be found easily.
- Arrange a lift home and some help for the first days, and book time off work.
What happens
The operation is done under general anaesthetic, usually with a tube that lets the lung being operated on be deflated. The surgeon reaches the lung through small keyhole cuts (or an open cut if needed), finds the nodule and removes a wedge of tissue around it with a stapling device.
Sometimes the nodule is small or deep and is marked beforehand (for example with a dye, coil or wire) to help locate it. The removed tissue may be examined straight away (a frozen section) to guide whether a bigger operation is needed at the same sitting.
A chest drain is usually placed to remove air and fluid and help the lung re-expand. You wake in a recovery area, and physiotherapy, pain relief and early walking start soon afterwards.
Is this operation right for me?
A good consultation should explore whether it's the right choice for you now — including reasons to wait or consider something else.
May not be suitable if…
- The cancer would be more completely removed by a lobectomy and your lung function allows it.
- The nodule is in a position where an adequate margin cannot be achieved with a wedge.
- Disease has spread beyond what surgery can control.
- You are not fit enough for a general anaesthetic and chest surgery.
- The diagnosis can be made by a less invasive test (for example image-guided biopsy).
Delay surgery if…
- You have an active chest infection or are unwell.
- Staging or lung-function results are incomplete.
- You are still smoking and could benefit from stopping first.
- Blood-thinning or other medicines need adjusting.
- Your heart rhythm or other conditions are unstable.
Alternatives to discuss
- Image-guided needle biopsy if the aim is only to get a diagnosis.
- Lobectomy or segmentectomy for a cancer that needs wider clearance.
- Stereotactic radiotherapy (SABR) for some early cancers in people unfit for surgery.
- Active monitoring of a very small or low-risk nodule with repeat scans.
- Systemic treatment decided by the MDT for more widespread disease.
Before you decide
Use this as a shared-decision checklist. The aim is not just “can this be done?”, but whether it is right for you, now, with the risks and alternatives clearly understood.
What matters most to me?
Think about symptoms, daily life, work, caring responsibilities, sport, fertility, travel, appearance and anxiety — the right choice depends on your priorities, not just the medical facts.
What are all my options?
Ask about waiting, monitoring, medicines, rehabilitation, a smaller or larger procedure, a different test, NHS referral, or a second opinion where that would help.
What would make me pause?
Active infection, pregnancy, unstable medical problems, smoking, medicines that increase bleeding, poor support at home, or feeling pressured are all reasons to slow down and get tailored advice.
What happens if I do nothing today?
For some problems, waiting is safe; for others, delay can make treatment harder. A good consultation should explain the trade-off in plain English.
Anaesthetic choices
The safest option depends on the operation, your health, the facility and your surgeon/anaesthetist. Ask what is planned and why.
Benefits
- Removes a nodule or small cancer while keeping more healthy lung
- Provides tissue for the laboratory to confirm a diagnosis
- Often suitable for people who could not safely have a whole lobe removed
- Usually keyhole, with less pain and a quicker recovery than a lobectomy
- Can remove one or more spreads (metastases) from another cancer
Risks & complications
- Pain at the wound or drain sites for a few weeks
- Air leak from the lung, keeping the chest drain in longer
- Tiredness and some breathlessness on exertion
- Bruising and discomfort around the cuts
- Chest infection needing antibiotics
- Fluid collecting around the lung needing drainage
- An abnormal heart rhythm such as atrial fibrillation
- Needing a larger operation than planned if findings change
- Bleeding needing a return to theatre or transfusion
- Conversion from keyhole to open surgery during the operation
- Serious breathing difficulty needing intensive care
- Failure to find or fully remove a very small nodule
A wedge is usually lower-burden than a lobectomy, but it is still a chest operation. The biggest uncertainties are whether the margin around a cancer is adequate and whether enough lymph glands can be assessed — narrow margins raise the chance of the cancer coming back locally. Ask your surgeon what they expect to remove and what happens if the laboratory suggests more surgery is needed.
Published figures to discuss
A wedge resection is generally lower-risk than a lobectomy because less lung is removed, but outcomes still vary with the approach and a person's health. Cancer-specific results depend heavily on the margin achieved and on lymph-gland assessment, so rates are best discussed for your individual case.
| Figure | Reported range | How to interpret it | Source / confidence |
|---|---|---|---|
| Death in hospital after a small (wedge) lung resection | Under about 1% | Lower than for lobectomy or pneumonectomy because less tissue is removed; still depends on fitness and other illness. | RCP — Lung cancer surgery survival (National Lung Cancer Audit)rcp.ac.ukPublished figure |
| Local recurrence after wedge resection for early cancer | Higher than after lobectomy when the margin is narrow; a margin of at least about 15 mm is reported to reduce local recurrence | Wedge resection can give inconsistent margins and less lymph-node sampling, which is why selection matters; exact rates vary by study and tumour. | Guide sourcesClinical context |
| Prolonged air leak | Reported in roughly 5–15% depending on definition and lung quality | Keeps the chest drain in for longer; more common in emphysematous lung. | RCP — Lung cancer surgery survival (National Lung Cancer Audit)rcp.ac.ukPublished figure |
These are literature figures, not a personalised prediction. Your own risks and likely benefits depend on your circumstances, your health, and how your care is carried out and followed up.
Recovery — what to expect, and when
Recovery is often quicker than after a lobectomy, especially with keyhole surgery. Many people are home within a few days and back to most activities within a few weeks, though tiredness and mild breathlessness can linger.
- Tiredness that improves over a few weeks
- Discomfort, numbness or tingling around the wounds and drain site
- Mild breathlessness on exertion that settles
- A cough or feeling of needing to clear the chest early on
- Waiting a week or two for the laboratory results
Aftercare
- Take pain relief as advised so you can breathe deeply, cough and walk.
- Do your breathing exercises and increase walking gradually.
- Keep wound and drain sites clean and dry and follow showering advice.
- Avoid heavy lifting and driving until your team says it is safe.
- Do not smoke, and ask for support to stop if needed.
- Watch for infection, increasing breathlessness or wound problems and report them.
- Attend follow-up and ask what the tissue showed and whether anything more is needed.
- Pain relief understood and collected
- Breathing-exercise and walking plan from the physiotherapist
- Help at home for the first few days
- Lift home and no-driving period understood
- Time off work booked
- Clinic and out-of-hours contact numbers saved
- Follow-up appointment and results discussion arranged
Scars and how they heal
Keyhole (VATS) surgery leaves a few small scars and a drain-site mark, which usually fade well. Open surgery leaves a larger scar between the ribs that can stay firm or numb. Altered sensation near the scars is common and may be long-lasting.
⚠ Get urgent help if…
- Worsening breathlessness or you cannot catch your breath
- Chest pain, a fast or irregular heartbeat, or feeling faint
- Fever, increasing cough, or green or bloody phlegm
- Coughing up blood
- A red, hot, swollen or painful calf, or sudden breathlessness (possible clot)
- Spreading redness, swelling or discharge from a wound
- Air bubbling or leaking from a drain site
Who to contact: your surgeon or clinic first (keep their number to hand). For urgent advice when you can't reach them, call NHS 111. In an emergency, call 999.
General guidance — it doesn't replace the specific advice your surgeon gives you.
Results & realistic expectations
A good result means the nodule is removed and the laboratory can tell you what it was. For a cancer, the team checks whether the margin of healthy tissue around it is adequate. The findings and any further plan are confirmed at the MDT meeting.
A wedge removes the target tissue, but it cannot prove that no disease remains elsewhere, and it does not always allow full lymph-gland staging. If the laboratory shows a cancer that needs wider removal, your team may recommend a further or larger operation, or other treatment.
For a small, low-risk early cancer in carefully selected people, a wedge resection can give good local control while preserving lung function, but the chance of the cancer returning locally is higher than after a lobectomy if the margin is narrow. For metastases, removing the deposit can help, but new spread can still appear, so follow-up scans are usual.
Combining with other procedures
A wedge is sometimes the first step at an operation: if a frozen-section result shows a cancer that needs more, the surgeon may proceed to a lobectomy or segmentectomy at the same sitting (this is discussed and consented beforehand). Lymph-gland sampling may be added. Further treatment after surgery is an MDT decision.
Follow-up & long-term care
You will usually be reviewed to check healing, discuss the results and agree any further steps. For cancer, follow-up scans and clinic reviews are common over several years. Report new breathlessness, chest pain, weight loss or coughing up blood between appointments.
- Keep up gentle activity and breathing exercises
- Stay smoke-free and accept stop-smoking support if needed
- Attend follow-up scans and clinic appointments
- Report new chest symptoms promptly
Revision and secondary surgery reality
- If a frozen-section or final result shows a cancer needing wider removal, a lobectomy or segmentectomy may be recommended or done at the same operation.
- An air leak that does not settle may need a longer drain or, rarely, further surgery.
- A planned keyhole operation may be converted to open if the nodule cannot be reached safely.
- Occasionally a very small nodule is difficult to locate, and marking or a repeat procedure is needed.
Ask your surgeon for their own revision rate, what counts as a revision, and what is included in the written aftercare policy.
What good aftercare looks like
- Early physiotherapy with breathing exercises and supported walking.
- A clear, written pain-relief plan so you can breathe deeply and cough.
- A named contact and out-of-hours route for breathlessness, infection or wound problems.
- A planned discussion of the laboratory results and any next steps with the MDT.
- Follow-up scans and clinic reviews where the indication is cancer.
What affects the cost
Costs vary a great deal between people and providers, and we don't publish prices. What matters is understanding what drives the cost and making sure your quote is complete. The main things that affect it:
- Whether it is done by keyhole (VATS) or open surgery
- Surgeon and anaesthetist fees
- Theatre time, any high-dependency care and length of stay
- Pre-operative tests such as lung function and staging scans
- Any nodule-marking procedure before surgery
- Laboratory analysis of the tissue, including any frozen section
- Follow-up appointments and scans under a separate plan
- Surgeon and anaesthetist fees
- Theatre, ward and any high-dependency costs
- Length-of-stay assumptions and what happens if you stay longer
- Pre-operative tests and any nodule marking
- Laboratory (histology) reporting, including frozen section
- Follow-up appointments and scans
- What is covered if a larger operation or a complication occurs
On the NHS? Wedge resection is routinely available on the NHS when clinically indicated and agreed by a multidisciplinary team; private care may be used for speed or choice of surgeon, not because it is unavailable on the NHS.

Consent traps and marketing red flags
These are not small details. They are often where patients lose choice, time to reflect, or realistic expectations.
Consent traps
- Not explaining that a wedge may give narrower margins and less lymph-gland staging than a lobectomy.
- No plan for what happens if the laboratory shows a cancer needing more surgery.
- Describing it as a minor procedure when it is still chest surgery under general anaesthetic.
- No discussion of alternatives such as image-guided biopsy or SABR radiotherapy.
- No clear instructions for air leak, infection or other common problems.
Marketing red flags
- Implying a wedge is always equivalent to a lobectomy for curing cancer.
- Promising complete cure from a small resection.
- Presenting recovery as effortless when it is still surgery.
- No mention of margins, lymph nodes or the MDT.
- Pressure to proceed before staging and fitness assessment are complete.
Choosing a surgeon safely
- Check your surgeon is on the GMC Specialist Register for this area.
- Make sure they practise at a CQC-registered location, and look for membership of bodies like BAAPS or BAPRAS.
- You're entitled to a two-stage consent process with time to reflect (a cooling-off period). The surgeon who will operate must consent you — not a salesperson.
- Be wary of pressure: time-limited offers, discounts or deposits taken before you've had time to think are red flags, not bargains.
- You're entitled to your total cost in writing — including aftercare and any revision — before you decide.
Questions to ask your medical professional
Take this to your consultation. A good surgeon will welcome every one of these.
- Why a wedge rather than a lobectomy or segmentectomy for me?
- What margin and lymph-gland sampling do you expect, and what if they are not enough?
- Will the nodule need marking beforehand so it can be found?
- What happens on the day if a frozen-section shows cancer?
- How will this affect my breathing, and what is the recovery?
- What follow-up will I need afterwards?
- Are you on the GMC Specialist Register for this area, and which Royal College or professional body are you a member of?
- Will you be the surgeon who carries out my operation, and who looks after me afterwards?
- What are the risks for someone like me, and how often do your own patients have a problem or need it repeated or redone?
- What does a realistic result look like — and what can this operation not achieve?
- What are my options, including waiting, doing nothing for now, or choosing a different approach?
- Can I have written information, results and aftercare instructions in a format I can use, including any accessibility or communication support I need?
- What is the total cost in writing, including any follow-ups, and how much time do I have to decide?
