Thoracoscopic Decortication

Thoracoscopic decortication

Thoracoscopic decortication is a minor and less painful chest surgery to remove a thick, fibrous type of layer known as a pleural peel which prevents the expansion of the lung. It is commonly applied to empyema, to trapped lung or to complications of long-standing pleural infections. This is a procedure done by Video-Assisted Thoracoscopic Surgery. 

Why Thoracoscopic Decortication is needed?

• Chronic empyema (Stage II/III)  
• Pleural peel caused trapped lung.  
• Puss filled collections of small fluid around the lung.  
• Chest blood with clots in it.  
• Selected cases of tuberculosis empyema.  
• Pleural scarring which restricts the functioning of the lungs.  
• In cases of failure of antibiotics, chest tube drainage, or clot‑breaking drugs.  

Thoracoscopic decortication surgery

VATS is applied to decorticate the thoracoscopic region to eliminate the fibrous peel and allow the trapped lung to expand. The process is less invasive and it usually requires 2-3 small incisions.

Preoperative Preparation  

• A CT scan of the chest, blood tests and lung functioning tests are administered to the patient.  
• Broad-spectrum antibiotics are initiated in case of the presence of empyema.  
• The patient is subject to general anaesthesia. Breathing tube is positioned in such a way that one of the lungs is ventilated and the other lung is collapsed.

Patient Positioning  

• The bad end of the patient is revealed on the side.  
• The operating table is able to be bent so that the spacing between the ribs will be increased.

Port Placement  

Small thoracoscopic ports (1-2 cm each): 2-3 small thoracoscopic ports are created:

• There is one camera port on the middle side line of the chest.
• Front-side and backside working ports.  
• There are instances when the carbon dioxide gas can be used to enhance the view.

Thoracoscopic Exploration  

A thoracoscope of high definition is used to examine:  

• The space around the lung.  
• The thick peel.  
• Any trapped pus or debris.  
• Lung and lung wall stuck in between the chest wall.

Adhesiolysis  

Pleural adhesions are loosened with the use of:  

• Thoracoscopic scissors.  
• Energy tools.  
• Blunt cutting.  

This will allow one to access the thick peel.

Removal of Pleural Peel (Decortication)  

• The surgeon finds the visceral peel which covers the collapsed lung.  
• It is removed and placed very carefully in layers one over the other beginning in the place it can most easily be reached.  
• The process of dissection is repeated until the lung is able to expand.  
• When the peel is extremely tough or contains calcium it is scraped off gradually and cautiously.  
• The epidermal peel is also exfoliated in case there is one.

Emergency Empyema or Debris Removal 

• All pus, inflamed tissue, blood clots and strands of fibrous tissue are removed.  
• The inside of the chest is washed with warm salt water till it is clean.

Lung Re-expansion Confirmation 

The anaesthesia team ensures that the lung re-expands to ensure that:  

• The lung fully expands.  
• No part is still trapped.  
• No major air leaks exist.  

Additional peeling is administered in case the lung is not fully expanded.

Chest Tube Placement  

A chest tube or two is usually placed:  

• One in the top as an air drain.  
• One in the bacteria to drain fluid.  

The tubes are attached to seal or suction.

Closure  

• Ports are stitched or stapled.  
• Dressings are applied.

Postoperative Monitoring  

• Monitoring of the patient takes place in ICU or high-dependency care at 12-24 hours.  
• Analgesics are treated, antibiotics are administered, and pulmonary exercises are initiated.  
• Removal of chest tubes is done when there is no air leakage and little drainage.

Surgery Time  

• Usually 1.5-3 hours, depending on the depth of the peel and the the complexity of the case.

Thoracoscopy decortication for empyema 

In a minimally invasive surgery on stage II (fibrinopurulent), and stage III (organized) empyema by means of VATS is called thoracoscopic decortication. The idea is to remove infected tissue, fibrous peel and scar tissue so that the lung has enough room to expand and breathing can go back to normal.

Why Thoracoscopic Decortication is required in Empyema?

Empyema passes through three stages:  

• Exudative- thick fluid that is normally managed with antibiotics and drainage.  
• Fibrinopurulent- thick pus, fibrous margins, and pockets.  
• Organized - Round fibrous peel is created around the lung and entraps it.  

The surgery is needed when:  

• The use of antibiotics or chest drainage is unsuccessful.  
• Pockets of trapped fluid are left behind.  
• The lung cannot expand.  
• A heavy peel will not allow one to breathe.  
• Empyema develops into a chronic or organized type.

Benefits of thoracoscopic decortication

Thoracoscopic decortication has many clinical, functional, and recovery-related benefits, particularly in contrast to open thoracotomy decortication.

Minimally Invasive Approach 

• Makes use of 2-3 small incisions as opposed to a big chest incision.  
• Reduced tissue and muscle injury.

Reduced Postoperative Pain  

• Smaller cuts mean less pain.  
• It helps to decrease the usage of potent pain medications.

Faster Lung Expansion  

• Peeling the lung allows the lung to expand rapidly, enhancing breathing and oxygen.  
• Improved empyema, trapped lung and scar lung.

Shorter Hospital Stay  

• The average stay of the patients is 3 -7 days.  
• Fast recovery implies that they are able to resume normal lives at an earlier date.

Faster Overall Recovery  

• The average recovery of most individuals back to normal life is 2-3 weeks.  
• The recovery is normally 46 weeks, which is quicker than open surgery.

Fewer Predispositions to Complications

• The risk of wound infection, haemorrhage or respiratory complications is decreased.
• Reduced post-operative pulmonary collapse due to reduced pain and early mobilization. 

Better Aesthetic Outcome  

• Minor incisions rather than a slender chest incision.  
• The appearance of the scars is more satisfactory to the patients.

Improved Surgery View  

• The camera used is a high definition that provides an enlarged image.  
• Assists the surgeon in peeling and removing the peel.

With Early Conversion, Lower Conversion Rates 

• VATS decortication is effective in early stage II empyema or early stage III empyema and does not necessitate the shift to open surgery.

Treats a large number of disorders

• Empyema (middle and late stages)  
• Trapped lung  
• Selected patients with tuberculosis pleural disease.  
• Chest clotted blood.  
• Post‑surgery scar lung

Improved Postoperative Pulmonary Function

• Premature re-expansion enhances breathing capacity in the long term.  
• It decreases the scar formation and chronic pulmonary constriction.

Reduction in the Total Healthcare Expenses

• Reduced treatment cost will be achieved through a reduced length of stay and reduced complications.

Thoracoscopic decortication recovery

Thoracoscopic (VATS) decortication is faster and less painful than an open chest surgery since they use small incisions and cause minimum muscle destruction. The majority of the patients recover their lung functions in no more than several weeks and resume normal lives.

Hospital Recovery  

• Leniency of stay - 3-7 days, depending on the severity of the infection and the extent of the expansion of the lung.  

Pain

• Mild to moderate.

• Controlled using oral analgesics or immediate nerve blockage or epidural.  

Chest Tubes

• One or two remain to remove fluid and air. 

They are commonly washed away in 2-5 days after:  

• Air leak stops.  
• Drainage is lower.  
• Chest X-ray reveals that there is good lung expansion.  

Breathing activities

• Breathing and incentive spirometry begin on Day 1.
• They aid in opening lungs and enhance breathing.

Walking

• Patients start walking in 24 hours.
• Early walking will minimize the chances of blood clots and assist the lungs to swell.

Recovery at Home

Breathing & Lung Function

• As the lung is completely expanded, breathing becomes easier.
• Practice breathing exercises on a daily basis in a few weeks.

Medications

• Take antibiotics which suit the infection, 2-4 weeks.
• Use pain medications when you feel the need.

Wound Care

• Keep dressings clean and dry.
• Minor cuts and wounds heal in 10 to 14 days. 

Activity

• Light activities: after 1 week
• Normal routine (office work): 2-3 weeks.
• Strenuous work or high intensity exercise: 4-6 weeks.
• Smoking and air pollution should be avoided.

Follow-Up Care

Follow-up visits

• Usually at 1, 3, and 6 weeks after surgery. 
• Chest X‑ray or CT scan

Done to confirm:

• Good lung expansion
• No more fluid buildup
• No complications
• Physiotherapy
• Continue with breathing exercises to achieve quicker recovery of lungs.

Thoracoscopic decortication complications

Thoracoscopic decortication is safe and the procedure of choice over open thoracotomy; however, certain complications can arise as with any chest operation. Most are amenable to treatment if recognized early. 

Prolonged Air Leak

• This is the most prevalent post-decortication issue.
• Occurs when the lung is feeble or ailmented.
• Usually clears in 3–7 days

May need:

• Longer chest tube drainage
• Suction
• Sometimes more surgery

Bleeding

Can come from:

• Chest wall vessels
• Intercostal arteries
• Raw lung after peel removal
• Normally ends with the video surgery.
• There is a rare need to perform a large open surgery.

Recurrent or Residual Empyema

• Not everything that is infected is swept away or peel is residual.

May need:

• Another chest tube
• More surgery (VATS or open)
• Longer antibiotics

Infection

• Cellulitis of the wound or chest wall.
• Unusual but captured by use of antibiotics and/or drainage.
• Predisposed to: Diabetics, Immune Compromised Individuals.

Atelectasis (Partial Lung Collapse)

• Due to the mucus plugs or inadequate treatment. 

Prevent with:

• Early walking
• Incentive breathing device
• Chest physiotherapy

Intractable Pleural Thickening

• In long-term chronic empyema, lung may be unable to enlarge completely.
• Restrictive lung problems are limited by causes.
• Uncommon in case of early surgery.

Postoperative Pain

• Typically mild moderate following VATS.
• Nerve pain may last weeks
• Take pain medicine and nerve-pain medicine orally and as needed.

Open Thoracotomy to Conversion

Needed in 5–15% when:

• Peel is very thick
• Fibrosis is dense
• Bleeding happens
• Anatomy is unclear
• More typical in chronic empyema.

Respiratory Complications

Includes:

• Pneumonia
• Bronchospasm
• Severe respiratory distress (rare)
• Increased vulnerability in smokers, aged individuals and those with reduced lung function.

Fluid Build Up (Chronic or Recurrent Pleural Effusion) 

• Was treated with repeated drain or medicine.
• Unusual requirement of surgery.

Cardiac Disorders (Uncommon)

• Rhythm problems (such as atrial fibrillation) 
• Typically not permanent and curable.

Mortality (Very Rare)

• Very uncommon (<1%)
• Typically as a result of serious infection, delayed empyema or numerous medical issues.

Conclusion

Thoracoscopic decortication is a very good surgery which is minimally invasive and is applicable in empyema and trapped lung and pleural scar. A camera and small cuts allow the doctor to take the scar right off, make the lung fully inflate, and restore the normal breathing. It is less painful, faster to recover, stays shorter in hospital and has fewer issues as compared to open surgery. It produces great results when established at the appropriate moment and supported with excellent breathing therapy and antibiotics and lasts long to improve lung performance.

FAQ

1. Is thoracoscopic decortication painful?

• Open surgery is far less painful than open surgery. Oral pain medicine is only required by most patients during the initial few days.

2. What will happen with the lung that fails to expand?

• When the lung is extremely scarred or adhesive to the pleura, it might fail to expand fully. Additional treatment or open surgery may be required in such cases, however, that is an unusual occurrence.

3. What is the success of thoracoscopic decortication?

• The success rates are 85 -95, particularly when performed at the initial stages of empyema.

4. Are the scars noticeable?

• The size of scar is minimal as the surgery requires 1-2 cm cuts.

5. Is repeat thoracoscopic decortication possible where necessary?

• Yes but with repeat surgeries, they are very infrequent since VATS tends to clear the area adequately and the lung is expanded.

6. Is it safe for elderly patients?

• Yes. It is frequently chosen in older or higher-risk patients because it is less invasive and results in fewer complications than open surgery.
