Empyema: An empyema (from Greek ἐμπύημα, "abscess") is a collection or gathering of pus within a naturally existing anatomical cavity. For example, pleural empyema is empyema of the pleural cavity.Pleural empyemaSubdural empyema: Subdural empyaema is a form of empyema in the subdural space.Parapneumonic effusionAsbestos-related diseases: Asbestos-related diseases are disorders of the lung and pleura caused by the inhalation of asbestos fibres. Asbestos-related diseases include non-malignant disorders such as asbestosis (pulmonary fibrosis due to asbestos), diffuse pleural thickening, pleural plaques, pleural effusion, rounded atelectasis and malignancies such as lung cancer and malignant mesothelioma.Drainage system (agriculture): An agricultural drainage system is a system by which the water level on or in the soil is controlled to enhance agricultural crop production.Chest tubeVideo-assisted thoracoscopic surgery: Video-assisted thoracoscopic surgery (VATS) is a type of thoracic surgery performed using a small video camera that is introduced into the patient's chest via a scope. The surgeon is able to view the instruments that are being used along with the anatomy on which the surgeon is operating.Bronchopleural fistula: A bronchopleural fistula (BPF) is a fistula between the pleural space and the lung. It sometimes develops following pneumonectomy or an infection.FibrothoraxResuscitative thoracotomy: A resuscitative thoracotomy (sometimes referred to as an emergency department thoracotomy or, colloquially, as "cracking the chest") is a thoracotomy typically done in order to resuscitate a person who has been severely injured after sustaining a severe trauma involving the thoracic cavity. For most persons with thoracic trauma the procedure is not necessary; only 15% of those with thoracic injury require the procedure.Max Schede: Max Schede (January 7, 1844 – December 31, 1902) was a German surgeon born in Arnsberg.Lung abscessLung cancer surgery: Lung cancer surgery describes the use of surgical operations in the treatment of lung cancer. It involves the surgical excision of cancer tissue from the lung.HemothoraxGastrocolic reflex: The gastrocolic reflex or gastrocolic response is one of a number of physiological reflexes controlling the motility, or peristalsis, of the gastrointestinal tract. It involves an increase in motility of the colon in response to stretch in the stomach and byproducts of digestion in the small intestine.
