Non-incisional pleurectomy-decortication for malignant pleural mesothelioma.

Pleurectomy-decortication (P/D) is lung-sparing surgery with curative intent for malignant pleural mesothelioma (MPM). Visceral pleurectomy is the most challenging step in this procedure. At the beginning of pleurectomy, a sharp pleural incision through the tumor is usually made to create the dissection plane between the visceral pleura and the lung parenchyma, which may cause the spread of tumor cells into the operation field. Here, we describe a sophisticated surgical technique of P/D without any pleural incision ("non-incisional P/D") to achieve en bloc removal of the entire pleura and tumor, which may improve postoperative survival by preventing tumor spread.
