Wedge Resection

Wedge resection surgery

A wedge resection is a form of surgery where a triangular shaped small area of tissue is excised out of an organ. It is usually done in the lungs, and may also be done to such organs as the breast, the liver, the ovary or the skin depending on the condition.

It is normally applied in cases where the target lesion is small, localized, and where the removal of an entire lobe or segment is not necessary.

Wedge Resection Indications

Lung

• Minor lung cancers at an early stage.
• Pulmonary nodules
• Metastatic lesions
• Lung biopsy for diagnosis
• Innocent lesions such as hamartomas.

Breast

• Small benign or malignant tumors which require tissue conservation.

Ovary

• Polycystic ovary syndrome (PCOS) wedge excision (rare today) 

Skin

• Reconstruction or tumor removal by removal of wedge-shaped tissue.

Benefits of Wedge Resection

• Minimal invasiveness option present (VATS/robotic)
• Destroys only the tissue that is diseased.
• Saves more organ functions than lobectomy/segmentectomy.
• Reduced hospitalization and rapid recovery.
• Elevated diagnostic rate in ground-glass opacity.

Thoracoscopic wedge resection

Wedged resection is a small triangular portion of lung which is removed thoracoscopically (VATS – Video Assisted Thoracoscopic Surgery) and hence the name thoracoscopic wedge resection. It is routinely performed on small nodules on the lungs, early cancers, benign tumors, and diagnostic biopsy.

This method does not require huge cuts and also has quicker healing parameters compared to open thoracotomy.

Wedge Resection Thoracoscopic Surgery:

Anaesthesia

• Intake of general anaesthesia.
• Applied ventilation (one lung momentarily collapsed due to surgery)

Patient Positioning

• Lateral decubitus position (side-lying) is given to the patient.

Incisions & Port Placement

• Usually 2–3 small incisions (5–12 mm)

Ports used for:

• Thoracoscope (camera)
• Stapler insertion
• Working instruments

Lung Visualization

• Camera gives us a close view of lung video which is magnified.
• Surgeon determines nodule or an area of disease.

Wedge Excision

• The lesion is excised as a triangular (wedge) piece of lung.
• Endoscopic staplers, which are utilized to cut and seal lung tissue.
• It includes a healthy tissue margin.

Specimen Removal

• Tissues that are excised through a protective bag.
• Referred to frozen section (elective) and final histopathology.

Air Leak Testing

• Staple line checked to exclude any air leakage.

Chest Tube Placement

• Diaphragm tube is inserted to remove air and fluid.
• Usually removed in 1–3 days

Closure

• Small lacerations that had been sutured.

Indications of Thoracoscopic Wedge Resection 

Diagnostic

• Single nodule assessment of the lungs.
• Biopsy interstitial lung disease.
• Undiagnosed lesions

Therapeutic

• Peripheral lung cancer at stages one and two (selected cases)
• Pulmonary metastases
• Benign tumors (hamartoma)
• Infection-related nodules
• Cyst or bulla resection

Advantages of Wedge Resection Thoracoscopic (VATS)

• Minimally invasive
• Smaller incisions
• Reduced pain over thoracotomy.
• Faster recovery
• Shorter hospital stay
• Lower risk of complications
• Premature working or normalization.

Wedge resection for lung cancer

• Wedge resection is a minimal lung operation in which a small triangular piece of lung tissue with the tumor and a small piece of normal lung tissue is resected.
• VATS (Video-Assisted Thoracoscopic Surgery) or robotic-assisted surgery is typically applied to perform wedge resection in the case of lung cancer.
• It is a non-invasive treatment to the lungs, although not a universal treatment with all cancers.

What Is the Use of Wedge Resection of Lung Cancer?

Wedge resection is normally applied to:

Minuscule, peripheral immature cancers

• Tumor size ≤2 cm
• They are found towards the outer lung surface.
• Good margins can be obtained

Patients that is not able to endure larger surgery

• Poor lung function
• High surgical risk or old age.
• COPD, fibrosis, cardiac problems.

Diagnostic uncertainty

• In cases where one is not certain whether a nodule is cancerous, and then a wedge removal offers a diagnosis tissue.

Metastatic lung lesions

• (Not lung cancer origin but metastasis of another type of cancer)

Technique: Wedge Resection of Lung cancer:

Anaesthesia and Setup

• General anaesthesia
• One-lung ventilation
• Small invasive VATS/robotic ports were employed.

Excision

• Piece of lung with tumor excised (triangular).
• Surgical staplers used
• Sufficient cancer-free margins are necessary.

Lymph Node Sampling

• Mediastinal node sampling/dissection is normally performed to tell the stage of cancer.

Closure

• Lung tested for air leaks
• Chest tube inserted
• Small incisions closed

Wedge resection procedure

A wedge resection is an operation aimed at resection of a small section of lung (triangular shaped) with the tumor or pathological area, as well as with a healthy tissue margin. It may be done through Thoracoscopic / VATS, robotic, or Open Thoracotomy.

Preoperative Preparation

• Medical examination, pulmonary tests, CT/sometimes PET-CT.
• Blood analysis and anesthesia.
• Fasting for 6–8 hours
• Informed consent
• Marking and planning of places of incisions (VATS/robotic).

Anaesthesia

• General anaesthesia is given
• It involves one-lung ventilation (only the lung on the opposite side is breathing).
• This gives a clear field of surgery.

Patient Positioning

• Patient in the lateral decubitus (lies on the side) position.
• Operated lung is kept upward

Incisions and Access

Wedge Resection by Thoracoscopic (VATS) Approach

• Two to three small incisions (5–12 mm in size) 
• Insertion of camera port (thoracoscope).
• 1-2 working ports, instruments and stapler.

Robotic Wedge Resection

• 3–4 small robotic ports
• Surgeon operated robotic arms remotely.

Traditional Open Thoracotomy

• Enlarged interribal incision.
• After exhaustion of minimally invasive approach.

Exploration of the Lung

• Pleural cavity and lung surface are visualized by camera.
• Surgeon detects the lesion.
• In case lesion is small or deep, intraoperative ultrasound can be applied.
• Checks of surgeon around structures.

Preparation and Learning of the Lung Tissue

• Thoracoscopic instruments are used in lifting target area.
• Sufficient oncologic planned (typically 2 cm or margin size equal to tumor size).

Wedge Excision

• A slice of lung that has the lesion is excised in a triangular shape.

Being performed with the help of endoscopic surgical staplers that:

• Cut the tissue
• Seal the lung edge
• The number of stapler firings could be varied with size.

Specimen Removal

• The wedge so removed is put in a bag.
• Extracted through one port

Sent to pathology for:

• Frozen section (optional)
• Final histopathology
• Margin evaluation
• Tumor typing and staging

Air Leak Test

• Surgeon reinflates the lung
• Bubbles Stapled area of checks.

Any leak is sealed up or reinforced with:

• Sealants
• Sutures
• Additional stapler firing

Sampling of Lymph Nodes (Especially in Cases of Cancer) 

• Sampling or removal of hilar and mediastinal lymph nodes is done.
• Notable to proper staging.

Chest Tube Placement

• One of the ports is utilised to place a chest drain.

Helps remove:

• Air
• Blood
• Fluid
• Normally erased after 1-3 days after lung has been expanded.

Closure

• Instruments removed
• Dissolvable sutures: These are sutures that are employed to close an incision. 
• Sterile dressing applied

Postoperative Care (Immediate)

• Further observation in recovery area.
• Oxygen support
• Pain management
• X-ray of the chest to ascertain lung enlargement.
• Strongly encouraged to walk either same day or next day.
• Incentive spirometer breathing exercises.

Wedge resection recovery

Wedge resection (thoracoscopic, robotic, or open) has an overall faster and less painful recovery compared to larger surgeries of the lung due to the removal of a small section of lung during the same surgery. The majority of the patients resume normal life in a couple of weeks.

Hospital Stay

Robotic

• 2–4 days in the hospital
• Chest tube should be taken out in 1-3 days.

Open Thoracotomy

• 5–7 days hospital stay
• Greater recovery because bigger incision.

Pain & Discomfort

• The post VATS/robotic pain is mild to moderate.
• Pain following thoracotomy is more intense but can be dealt with.
• Gradual reduction of pain takes place after 2-3 weeks.

Medications given:

• Oral analgesics 
• Occasionally nerve pain drugs.
• Thoracotomy can be done using nerve blocks or epidurals.
• To prevent complications with the lungs, it is necessary to control pain that will improve deep breathing.

Breathing & Lung Recovery

• Light shortness of breath at first.
• Apply incentive spirometer 8-10 time/hour.
• Pneumonia is prevented through deep breathing exercises.
• Mild cough is normal
• Complete expansion of lungs enhances in 2-6 weeks.

Incision & Wound Care

• Keep wounds clean and dry
• Stitches tend to be absorbable; otherwise, removed in 7-10 days.
• No soaking of wounds (bath/swimming) during 2 weeks.
• Observe redness, discharge, or fever.

Physical Activity Timeline

First Week

• Walk multiple times daily
• Light movements, do not strain.
• No heavy lifting

2–4 Weeks

4–6 Weeks

Can resume:

• Driving
• Regular household work
• Light exercise (walking treadmill, bicycling)

6–8 Weeks

• Strenuous activity, weight lifting, and exercise.
• Slow recovery based on energy.

Chest Tube Site Care

After tube removal:

• Small dressing applied

• Frequent small meals, when one is not hungry.

Reconstruction after Wedge Resection

You can usually drive after:

• 7–10 days for VATS/robotic
• 2–3 weeks for thoracotomy
• Only in a case when pain is managed and no narcotics are in use.

Return to Work

Sedentary jobs

• 1–2 weeks after VATS
• 3–4 weeks after open surgery

Physical labour jobs

• 4-8 weeks, based on healing and fitness.

Follow-up Appointments

• The initial follow-up: 7-10 days after discharge. 
• Review of pathology report in cancer cases.
• Repeat chest x-ray to check on the expansion of lungs.
• CT scans after every 6-12 months in case of cancer resection.

Long-Term Recovery

• Fatigue may last 3–6 weeks
• Breathing slowly improves
• By 6-8 weeks, most of the patients resume normal life.

Wedge resection cost India

Following are the determinants of the cost of a wedge resection surgery in India:

Surgery access type / method

• Less invasive techniques such as Video-Assisted Thoracoscopic Surgery / VATS, or robotic are more likely to be more expensive than open surgery. 
• More time and consumable used on more sophisticated equipment (endostaplers, video towers, robotic arms). 
• Nonetheless, in many cases, minimally invasive surgery can reduce the duration of hospitalization, and this can partially compensate the expenditure.

Hospital category, city and infrastructure

• Metros (Delhi, Mumbai, Bangalore) and premium corporate hospitals charge a higher fee. 
• The specialist thoracic-oncology service and the high nurse: patient ratio hospitals are also costly. 
• Room type (single deluxe or shared ward) is of additional expense. 

Experience in surgery, team and technology

• A thoracic team / oncology of high experience may be more expensive than a less experienced team. 
• When the surgery partially requires expert assistance (anaesthesiology, lung-function, ICU), the expenses increase.

Pre-operative diagnosis and staging

• Specialized imaging (CT, PET-CT), lung volume tests, cardiology clearance is also added to the overall cost. 
• When staging a disease with high progression, i.e. a case that needs to have lymph-nodes excised, the demand of the procedure is more complicated, and costs rise.

Severity and scope of illness and surgery

• In case, it is deeper, or is close to significant vessels, and the patient has poor lung functioning, then it is a more complicated surgery, and it costs more. 
• Other procedures such as sampling of lymph node, prolonged anaesthesia and extended period of operation increase expenses.

Hospital stay + Intensive Care Unit / post-surgery

• The increase in cost is caused by complications or longer stay. 
• ICU, ventilator support, blood transfusions, extended stay is all expensive.

Consumables & implants

• Additional costs are staplers, special instruments, and single use disposables.
• In case of robotic surgery, robotic consumable is more expensive.

After-care services & follow-up

• Physiotherapy, breathing exercises, follow-ups (imaging), and medications all contribute to higher out-of-pocket expenses. 
• Accommodation, after operative diet, further tests, etc.

Conclusion

Wedge resection is another useful surgery that preserves the lung and therefore it is performed when the lung cancer is small and at an early stage or a benign nodule or a diagnostic lung tissue. It has its benefits that include minimal removal of lung tissue, quicker recovery, and it can be relevant in patients that fail to tolerate the more invasive procedures such as lobectomy. The latest thoracoscopic or robotic surgeries have greatly lowered the amount of postoperative pain, length of hospitalization, and complications and the wedge resection is a more desirable option to use in case of clinical relevance. In most cases, recovery is made easier through effective breathing, wound management and shunning of strenuous activities within a few weeks.

Yes. It is often preferred for:

• Elderly individuals
• Those with low lung function
• Patients who are inappropriate to lobectomy
• It is safer when using minimal invasion methods.

3. Should I receive chemotherapy or radiation following a wedge resection?

• Only if cancer is found and:
• Margins are inadequate
• Lymph nodes are positive
• The tumor itself is aggressive.

4.Is wedge resection safe?

• Yes. It is considered a safe and effective procedure with a high success rate, especially when performed by experienced thoracic surgeons.
