Things worth knowing about "Decortication"

Decortication is a surgical procedure to remove a thickened or scarred tissue layer from the surface of the lung or other organs, restoring normal function.

What is Decortication?

Decortication is a surgical procedure in which a thickened, scarred, or inflamed tissue layer – known as the cortex or fibrous peel – is removed from the surface of an organ. Most commonly, this procedure involves the lung and the surrounding pleural cavity (the space between the lung and the chest wall). The goal is to restore normal lung expansion and respiratory function.

Causes and Indications

Decortication becomes necessary when inflammation, infection, or injury leads to the formation of a rigid fibrous layer on the lung surface or pleura. Common causes and indications include:

Empyema: A collection of pus in the pleural space, often as a complication of pneumonia
Fibrothorax: Scarring of the pleural cavity following chronic inflammation or bleeding
Hemothorax: Accumulation of blood in the pleural space leading to scar tissue formation
Tuberculosis: Chronic infection with a tendency for fibrosis and scarring
Chronic pleuritis: Long-term inflammation of the pleura

Surgical Procedure

Decortication is performed under general anesthesia. The surgeon accesses the chest cavity either through a conventional incision (thoracotomy) or minimally invasively via video-assisted thoracoscopic surgery (VATS). The thickened fibrous layer is then carefully peeled away from the lung surface and the inner chest wall, preserving the healthy tissue beneath. After the procedure, a chest drain is typically left in place to allow fluid and air to escape.

Minimally Invasive Technique (VATS)

Video-assisted thoracoscopic surgery involves only small incisions through which a camera and surgical instruments are inserted. This approach is less invasive, shortens hospital stays, and allows for faster recovery.

Open Thoracotomy

For extensive or heavily adhered fibrous layers, open surgery may be required. While more demanding, this approach allows a more complete removal of the affected tissue.

Risks and Possible Complications

As with all surgical procedures, decortication carries certain risks, including:

Intraoperative or postoperative bleeding
Wound infection or recurrent empyema
Air leak from the lung (pneumothorax)
Injury to neighboring structures (diaphragm, nerves, blood vessels)
Incomplete re-expansion of the lung
General risks associated with anesthesia

Aftercare and Recovery

Following surgery, patients typically remain in the hospital for several days. The chest drain is removed once the lung has fully re-expanded and drainage has ceased. Breathing exercises and physiotherapy support healing and help gradually restore lung capacity. Full recovery may take several weeks to months, depending on the extent of the procedure.

Prognosis

The prognosis after decortication is generally favorable when the procedure is performed early and completely. Many patients experience significant improvements in breathing and quality of life. When empyema or fibrothorax is treated promptly, permanent lung damage can often be prevented.
