Decorticate

To surgically peel away a thickened, fibrous rind that has formed around an organ, most often the lung. In asbestos disease, this means stripping a stiff layer of scar tissue off the lung's surface so the lung can expand again. The procedure itself is called a decortication.

Origin

From the Latin de- (away) and cortex (bark or rind). Surgeons began using the term in the late 19th century to describe peeling a thick fibrous "peel" off a trapped lung, particularly after tuberculosis or empyema.

Significance in Asbestos Context

For patients with asbestos-related disease, decortication is most often discussed in two settings: (1) diffuse pleural thickening or a trapped lung from heavy scarring, where peeling the rind can restore breathing capacity, and (2) pleural mesothelioma, where it is performed as part of a pleurectomy/decortication (P/D), a lung-sparing cancer operation that removes the diseased pleura and any visible tumor without removing the lung itself. P/D is now favored over the more extensive extrapleural pneumonectomy (EPP) at many centers because it generally has lower mortality and better quality of life. The tissue removed during decortication is also valuable evidence: pathology slides and fiber analysis from this material can document asbestos exposure for both medical and legal purposes.

Example Sentence

After his mesothelioma diagnosis, the thoracic surgeon recommended a pleurectomy/decortication rather than removing the entire lung.

Notes

• Ask whether your surgery is a decortication alone (for benign scarring or trapped lung) or a pleurectomy/decortication (for mesothelioma). They are different operations with different goals.
• If mesothelioma is suspected or confirmed, ask that removed tissue be sent for both pathology review and, where possible, fiber burden analysis; preserved tissue blocks can be critical later for diagnosis confirmation and legal claims.
• Request copies of the operative report, pathology report, and pre- and post-op imaging. These documents establish disease extent and treatment history.
• Seek evaluation at a high-volume mesothelioma or thoracic surgery center; outcomes for P/D depend heavily on surgeon experience.
• Discuss realistic goals before surgery: decortication can improve breathing and, in mesothelioma, is usually combined with chemotherapy and/or radiation rather than offered as a stand-alone cure.
