Pleurectomy and decortication is often offered to patients not healthy enough to undergo pneumonectomy or to patients whose tumors require a less extensive amount of resection.
The patient is placed lying on their side, and an S-shaped thoracotomy incision is made. The sixth rib is resected and the space between the lung and the chest cavity is dissected. The tumor is dissected away from the chest wall. After a sufficient area of chest wall has been freed, a chest retractor is inserted.
The pleura now can be moved from the mediastinum. Once the upper portion of the lung is completely detached from the chest wall, the vessels entering the lung are exposed. On the left side, the esophagus and aorta are identified and the dissected. On the right side, the superior vena cava is dissected away from the tissue and tumor being removed. The dissection then continues behind the pericardium.
In some patients, involvement of the diaphragm necessitates a full-thickness resection of the diaphragm muscle.
Once the dissection is completed to expose the vessels connecting the heart and lungs, the space between the lung and chest wall is opened decortication of the visceral pleura (membranous outer layer of the lung) is performed. During decortication, the lung is deflated to reduce blood loss. Most patients require blood transfusion during the procedure. Lymph node is also performed.
Once the tumor is removed, reconstruction of the pericardium (sac around the heart) and diaphragm, if required, is performed. If the diaphragm is largely intact, it can be pulled downward and to prevent upward movement and improve ventilation.
On the right side, reconstruction of the diaphragm is performed with a double layer of mesh. On the left, Gore-Tex is used because thicker, non-absorbable material is required. The prosthesis is secured laterally by placing sutures around the ribs.
An electrocoagulator may be used to help control bleeding from the chest wall. Three chest tubes are placed at the top, and a right-angled tube is placed along the diaphragm to control air leaks that are anticipated and should permit full refilling of the lung.
