Objective:
Pleurectomy/decortication has been preferably employed as a curative-intent surgery for malignant pleural mesothelioma. However, visceral pleurectomy during pleurectomy/decortication provides technical challenges. For visceral pleurectomy, pleural incisions are commonly made to create a dissection plane between the visceral pleura and the lung parenchyma, which may cause tumor dissemination and may not allow en bloc complete resection of the entire pleura. To overcome such potential disadvantages, we have developed a novel surgical technique without any pleural incision (non-incisional pleurectomy/decortication) to achieve en bloc removal of the entire pleura.
Methods:
A total of 36 consecutive patients who underwent non-incisional pleurectomy/decortication for malignant pleural mesothelioma from January 2017 through December 2020 in our institute were retrospectively reviewed to assess the feasibility.
Results:
Macroscopic complete resection was achieved in 31 patients (86.1%) with non-incisional pleurectomy/decortication. In the majority of patients (n = 29), en bloc complete resection of the entire pleura was achieved (without pleural laceration in 10 and with some pleural laceration in 19 patients). The total operation time and the duration of visceral pleurectomy were significantly shorter as compared with those for conventional pleurectomy/decortication (median, 350 versus 506 min [P = 0.011], and 43 versus 97 min [P < 0.001], respectively). Among 36 patients who underwent non-incisional pleurectomy/decortication, postoperative complications developed in 13 patients (36.1%), and one patient died on the postoperative day 95 caused by aggressive tumor progression of residual tumor.
Conclusions:
Non-incisional pleurectomy/decortication is a fast and feasible technique to achieve en bloc macroscopic complete resection for malignant pleural mesothelioma.

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...

A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.
