Abstract:
Recurrent pleural effusion, which is commonly seen in clinical practice, compromises patient quality of life, especially in patients with advanced malignant disease. The therapeutic approach to the pleural space involves a wide range of techniques, including aggressive procedures such as pleurectomy. Among such techniques, pleurodesis is the most frequently used. Pleurodesis can be induced through the insertion of pleural catheters, as well as through major surgical procedures (such as thoracotomy). There are various recommended sclerosing agents, including talc (which is the most widely used), silver nitrate and, recently, proliferative cytokines. This article summarizes the principal approaches to the treatment of recurrent pleural effusion, pleurodesis in particular, addressing the indications for, as well as the advantages and disadvantages of, their application in daily pulmonology practice.

Pleural Effusion II: Symptoms and Management
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.

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 to...
Endoscopic Studies II: Thoracocentesis
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...
