Mesothelioma Pleurectomy With Decortication (P/D)
The pleurectomy with decortication is a surgical procedure for patients diagnosed with pleural mesothelioma. The surgery spares a patient’s lung by removing the pleural lining.
The Lung-Saving Surgical Option
The pleurectomy with decortication (P/D) is a lung-saving, alternative surgery to the extrapleural pneumonectomy (EPP). The P/D removes the diseased lining of a patient’s lung along with any other tumors in the chest.
Many mesothelioma specialists prefer the P/D over the EPP because it is just as effective and patients often have a better quality of life. The procedure has been proven to improve a patient’s fatigue, dyspnea symptoms, and to help control fluid buildup.
Key Points About the Pleurectomy/Decortication
The life expectancy for patients who experience a P/D is comparable to those who have an EPP. The life expectancy is about 10 to 25 months after surgery with many patients exceeding that statistic.
The pleurectomy with decortication was developed by Dr. Robert Cameron of the UCLA Medical Center. He developed the procedure as an alternative treatment option for pleural mesothelioma patients in the 1990s.
The ideal candidate for a P/D is a patient with a stage 1 or 2 diagnosis. Patients are not excluded from the procedure due to their age. In fact, the surgery has been proven to be safe for individuals that are 70 years of age or older. Patients must exhibit good overall health and their tumor(s) must not have spread past the lining of their lung (the pleura).

History and Philosophy Behind the Pleurectomy
There are only two surgical procedures available to treat pleural mesothelioma: pleurectomy/decortication (P/D) and the extrapleural pneumonectomy (EPP).
P/D is a relatively recent procedure developed for treating malignant pleural mesothelioma. This palliative procedure was developed in the mid ‘90s. The median survival for mesothelioma patients treated with P/D is no different than patients treated with EPP.
Research suggests that a P/D causes the least harm to a patient undergoing surgery.
Origin: Before Decortication
A pleurectomy is the part of the procedure that involves the removal of the lining surrounding the lung, known as the pleura. Removing the affected pleura allows for greater breathing comfort, but doesn’t do much to improve a patient’s survival time. For this reason, the EPP was used more often in patients who were eligible for the surgery.
Decortication is the second part of the P/D after the pleura has been removed. It focuses on excising any remaining visible tumors surrounding the patient’s lung.
A Less Radical Answer to the Extrapleural Pneumonectomy?
Pleurectomy/decortication is increasing in popularity among mesothelioma doctors. The P/D developed out of a desire to implement a procedure as beneficial, but less radical, than the EPP.
Controversy remains over whether the P/D is the most optimal procedure for pleural mesothelioma patients. Some medical professionals argue that the EPP is unnecessary and can still leave cancer behind. Other experts believe that P/D doesn’t do enough to remove a patient’s cancer.
Many doctors, such as Dr. Raja Flores argue that the type of surgery depends on the individual. Dr. Flores favors the P/D when possible but sometimes opts for the EPP if the extent of the tumor is too severe.
The most important factor in determining which procedure to use depends on a patient’s diagnosis. The extent of a patient’s cancer and cell type often dictates the type of surgery that is most beneficial for them.

Who is Eligible for Pleurectomy Surgery?
Before undergoing any major surgery, patients have to be physically fit enough to handle the stress and recovery associated with surgery. For these reasons, patients are monitored to assure they are capable of handling the procedure. This is imperative for reducing operative mortality rates.
Preoperative Patient Evaluation
- Age and fitness evaluation
- Blood chemistries
- Pulmonary function evaluation
- CT-scan and MRI of chest
- Echocardiogram (cardiac evaluation)
- Pleural biopsy including cell type
Aside from being capable of handling the surgery, the patient’s diagnosis is one of the most important aspects used to determine whether they are eligible for the procedure. Typically, only patients with stage 1 or stage 2 pleural mesothelioma are eligible for a P/D.
Patients diagnosed with epithelioid mesothelioma are typically treated with a P/D. Epithelial mesothelioma is the most common and most treatable mesothelioma cell type. Patients with this type of mesothelioma often have more treatment options and a better prognosis, which makes them ideal surgical candidates for the P/D.
“Not resectable” means the tumor is deemed too hard for the surgeon to remove without damaging the lung. In these cases, the tumor has spread into the fissures separating the lung where the doctor cannot reach surgically.
Pleurectomy Surgical Procedure
Before a P/D begins, the patient is placed under general anesthesia. A patient may be under general anesthesia anywhere from 4 to 6 hours.
Next, an endotracheal tube is inserted into the trachea to keep the lungs inflated. During a P/D, the endotracheal tube is also used as a tool to create a controlled deflation of the lung. Doing this helps the surgeon have better access to reach difficult parts of the tumor.
4 Steps of the Pleurectomy/Decortication
- 1Incision (thoracotomy) – An incision is made from the patient’s back to under the pectoral muscle to enter their chest cavity. The sixth rib is removed to allow surgeons appropriate access.
- 2Pleurectomy – The parietal (outer) pleura is removed along with any affected tissues in the chest wall, diaphragm or pericardium.
- 3Decortication – The visceral (inner) pleura is separated from the lung to excise any visible tumors. Sections of the visceral pleura may be removed if deemed necessary. This is the most tedious part of the surgery.
- 4Reconstruction – Sutures are used where necessary to close the chest. Gore-Tex, or a similar material, is used in cases where a considerable amount of the diaphragm has to be removed.
After the patient is stabilized, three chest tubes are inserted to ensure the lung re-expands normally and to allow the pleural space to drain. These tubes are critical for a healthy recovery.
Alternative Method of the P/D
Alternatively, patients whose preoperative assessment didn’t meet the standards may undergo a different procedure using video-assisted thoracic surgery.
Traditionally, the lung is accessed by means of a thoracotomy, which is an incision between the ribs of the patient on the side of the affected lung. When patients aren’t fit enough for this procedure, a thoracoscopy can be used as an alternative.
Thoracoscopies involve the employment of VATS to complete the procedure. Rather than making a large incision to gain full access to the lung, three small incisions, or port sites, are made on the side of the affected lung. One of the port sites hosts an endoscope, which is a flexible tool with a tiny camera on the end.
Once the incisions are made, any pleural effusions (excess liquid in the chest cavity) are drained. The camera is then inserted to see inside the patient’s chest cavity, while the other port sites are used to complete the P/D using special tools.
Intraoperative Treatment Options
Intraoperative treatments can be used during P/D surgery. Using this type of treatment allows doctors to have direct access to a patient’s tumors.
Many patients take advantage of intraoperative radiation therapy(IORT) as part of their P/D. IORT is introduced before the chest is closed. This allows radiation to kill remaining microscopic cancer cells. These are cells that could not be removed with surgery without passing radiation through extra tissue.
Heated intraoperative chemotherapy is also being offered at some institutions after a P/D procedure. This allows doctors to put chemotherapy in direct contact with any remaining microscopic cancer cells. In recent studies, this process has shown a median survival of 35 months.
Recovery After Pleurectomy Surgery
After surgery, patients can expect to spend 5-7 days in the hospital for recovery. They are moved to a recovery room immediately after waking from the anesthesia.
During this time, about 3-4 hours, patients have all their vitals monitored to ensure the surgery was a success. This includes heart rate, blood pressure, breathing rate and oxygen levels. An epidural or morphine pump is used for pain management, along with prescribed pain pills.
The patient is also on a respirator directly after the surgery. A respirator is necessary to guarantee the patient is getting enough oxygen. Breathing is typically labored for a few days following surgery. Patients are also fitted with chest tubes to help the lungs stay inflated and drain any fluid buildup from surgery.
Patients are also started on breathing and coughing exercises with the help of a physiotherapist. These exercises not only help recuperation but prevent infection and pneumonia as well. Infection is possible after any surgery and P/D is no exception.
Coughing helps to rid the lungs of sputum, which tends to build up after major lung surgeries. Ridding the lungs of sputum helps prevent bacteria from forming a haven in the body.
After a week of being monitored patients are allowed to check out of the hospital. The recovery process after the patient goes home takes about three more weeks. During this time patients will continue their breathing and coughing exercises as well as walking exercises.
On the whole, total recovery from a P/D takes only about one month for most patients. Afterwards, patients can assume a normal life, but still must be careful to avoid overexertion.
Benefits of Pleurectomy
The primary benefit of undergoing P/D is improving patients’ life expectancy. The average life expectancy of a patient with pleural mesothelioma is approximately a year. Statistically, only about 5% of patients survive for five years. However, those who had a P/D saw a marked improvement. P/D has also demonstrated better overall survival and decreased mortality if a patient’s mesothelioma recurs.
The P/D was developed with the intent to be more beneficial than the EPP. The obvious benefit being the saving of the affected lung. Recovery time for this procedure is also remarkably low in comparison to an EPP.
P/D is also beneficial to patients with minor cardiac issues. Patients who have any heart conditions are most likely not eligible for an EPP. Since the lungs and heart work together to support each other, a patient with a heart condition may not be strong enough to rely on only having one lung. However, these patients may be able to reap the benefits of a P/D because their affected lung will remain intact.
