Thoracoscopy
Thoracoscopy is a medical procedure involving internal examination, biopsy and/or resection/ drainage of disease or masses within the pleural cavity, usually with video assistance. Thoracoscopy may be performed either under general anaesthesia or under sedation with local anaesthetic. History Thoracoscopy was first performed by Sir Francis Cruise of the Mater Misericordiae Hospital in Dublin in conjunction with Dr Samuel Gordon in 1865. It was further developed by Hans Christian Jacobaeus, a Swedish internist in 1910 for the treatment of tuberculous intra-thoracic adhesions. He used a cystoscope to examine the thoracic cavity, developing his technique over the next twenty years. Today, thoracoscopy is performed using specialized thoracoscopes. These instruments include a light source and a lens for viewing and may have ports through which other instruments may be inserted for the purpose of tissue removal and manipulation.

Pleural Cavity
The pleural cavity, pleural space, or interpleural space is the potential space between the pleurae of the pleural sac that surrounds each lung. A small amount of serous pleural fluid is maintained in the pleural cavity to enable lubrication between the membranes, and also to create a pressure gradient. The serous membrane that covers the surface of the lung is the visceral pleura and is separated from the outer membrane the parietal pleura by just the film of pleural fluid in the pleural cavity. The visceral pleura follows the fissures of the lung and the root of the lung structures. The parietal pleura is attached to the mediastinum, the upper surface of the diaphragm, and to the inside of the ribcage. Structure In humans, the left and right lungs are completely separated by the mediastinum, and there is no communication between their pleural cavities. Therefore, in cases of a unilateral pneumothorax, the contralateral lung will remain functioning normally unless ther ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hans Christian Jacobaeus
Hans Christian Jacobaeus (29 May 1879 – 29 October 1937) was a Swedish internist born in Skarhult. In 1916 he became a professor at the Karolinska Institutet in Stockholm. From 1925 until his death in 1937, he was a member of the Nobel Prize Committee. Jacobaeus was an important figure in regards to modern laparoscopy and thoracoscopy. In 1910 he is credited with performing the first thoracoscopic diagnosis with a cystoscope, being used on a patient with tubercular intra-thoracic adhesions. In 1910, he published an article titled ''Über die Möglichkeit die Zystoskopie bei Untersuchung seröser Höhlungen anzuwenden'' (The Possibilities for Performing Cystoscopy in Examinations of Serous Cavities) in the journal ''Münchner Medizinischen Wochenschrift''. He also did pioneer work involving abdominal endoscopy, which he called laparoscopy. The term "laparoscopy" was introduced into clinical medicine and is used up to now although Jacobaeus initially called the procedure ...

Lymphangioma
Lymphangiomas are malformations of the lymphatic system characterized by lesions that are thin-walled cysts; these cysts can be macroscopic, as in a cystic hygroma, or microscopic. The lymphatic system is the network of vessels responsible for returning to the venous system excess fluid from tissues as well as the lymph nodes that filter this fluid for signs of pathogens. These malformations can occur at any age and may involve any part of the body, but 90% occur in children less than 2 years of age and involve the head and neck. These malformations are either congenital or acquired. Congenital lymphangiomas are often associated with chromosomal abnormalities such as Turner syndrome, although they can also exist in isolation. Lymphangiomas are commonly diagnosed before birth using fetal ultrasonography. Acquired lymphangiomas may result from trauma, inflammation, or lymphatic obstruction. Most lymphangiomas are benign lesions that result only in a soft, slow-growing, "dough ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Light Source
Light or visible light is electromagnetic radiation that can be perceived by the human eye. Visible light is usually defined as having wavelengths in the range of 400–700 nanometres (nm), corresponding to frequencies of 750–420 terahertz, between the infrared (with longer wavelengths) and the ultraviolet (with shorter wavelengths). In physics, the term "light" may refer more broadly to electromagnetic radiation of any wavelength, whether visible or not. In this sense, gamma rays, X-rays, microwaves and radio waves are also light. The primary properties of light are intensity, propagation direction, frequency or wavelength spectrum and polarization. Its speed in a vacuum, 299 792 458 metres a second (m/s), is one of the fundamental constants of nature. Like all types of electromagnetic radiation, visible light propagates by massless elementary particles called photons that represents the quanta of electromagnetic field, and can be analyzed as both waves and particle ...

VATS Lobectomy
Video-assisted thoracoscopic surgery (VATS) lobectomy is an approach to lung cancer surgery. Traditional approach to lung cancer surgery: thoracotomy Anatomic lung resection, i.e. pulmonary lobectomy or pneumonectomy, in conjunction with removal of the lymph nodes from the mediastinum is the treatment modality that provides the greatest chance of long-term survival in patients with early stage non-small cell lung cancer. Anatomic lung resections require a dissection of the pulmonary hilum with individual ligation and division of the pulmonary artery, pulmonary vein, and the bronchus where these enter the lung. In the setting of lung cancer, the rationale for anatomic lung resection is a complete removal of a lung tumor along with the lymphatics that drain that tumor to assure that any tumor cells present in the lymphatics will also be removed; lesser resections have been shown to be associated with a higher risk of local recurrence and diminished long-term survival.

Cardiothoracic Surgery
Cardiothoracic surgery is the field of medicine involved in surgical treatment of organs inside the thoracic cavity — generally treatment of conditions of the heart ( heart disease), lungs ( lung disease), and other pleural or mediastinal structures. In most countries, cardiothoracic surgery is further subspecialized into cardiac surgery (involving the heart and the great vessels) and thoracic surgery (involving the lungs, esophagus, thymus, etc.); the exceptions are the United States, Australia, New Zealand, the United Kingdom, and some European Union countries such as Portugal. Training A cardiac surgery residency typically comprises anywhere from four to six years (or longer) of training to become a fully qualified surgeon. Cardiac surgery training may be combined with thoracic surgery and / or vascular surgery and called cardiovascular (CV) / cardiothoracic (CT) / cardiovascular thoracic (CVT) surgery. Cardiac surgeons may enter a cardiac surgery residency dir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Interstitial Lung Disease
Interstitial lung disease (ILD), or diffuse parenchymal lung disease (DPLD), is a group of respiratory diseases affecting the interstitium (the tissue and space around the alveoli (air sacs)) of the lungs. It concerns alveolar epithelium, pulmonary capillary endothelium, basement membrane, and perivascular and perilymphatic tissues. It may occur when an injury to the lungs triggers an abnormal healing response. Ordinarily, the body generates just the right amount of tissue to repair damage, but in interstitial lung disease, the repair process is disrupted, and the tissue around the air sacs (alveoli) becomes scarred and thickened. This makes it more difficult for oxygen to pass into the bloodstream. The disease presents itself with the following symptoms: shortness of breath, nonproductive coughing, fatigue, and weight loss, which tend to develop slowly, over several months. The average rate of survival for someone with this disease is between three and five years. The term I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lobectomy (lung)
Lobectomy of the lung is a surgical operation where a lobe of the lung is removed. It is done to remove a portion of diseased lung, such as early stage lung cancer. In addition to cancer, a lobectomy can also help to treat such things as a fungal infection, emphysema and tuberculosis. Administration The most common type of lobectomy is known as a thoracotomy. When this type of surgery is done the chest is opened up. An incision will be made on the side of the chest where the affected area of the lung is located. The incision will be in between the two ribs located in that area. The surgeon will then be able to have access to the chest cavity once the two involved ribs have been pried open. The surgeon will then be able to remove the lobe where the problem is contained. Another less invasive lobectomy procedure can be performed through a video assisted surgery, where the surgeon does not need to pry the two ribs open in order to get access. A few small incisions are made an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surgical Staple
Surgical staples are specialized staples used in surgery in place of sutures to close skin wounds or connect or remove parts of the bowels or lungs. The use of staples over sutures reduces the local inflammatory response, width of the wound, and time it takes to close. A more recent development, from the 1990s, uses clips instead of staples for some applications; this does not require the staple to penetrate. History The technique was pioneered by "father of surgical stapling", Hungarian surgeon Hümér Hültl. Hultl's prototype stapler of 1908 weighed , and required two hours to assemble and load. The technology was refined in the 1950s in the Soviet Union, allowing for the first commercially produced re-usable stapling devices for creation of bowel and vascular anastomoses. Mark M. Ravitch brought a sample of stapling device after attending a surgical conference in USSR, and introduced it to entrepreneur Leon C. Hirsch, who founded the United States Surgical Corporati ...

Endoscopes
An endoscopy is a procedure used in medicine to look inside the body. The endoscopy procedure uses an endoscope to examine the interior of a hollow organ or cavity of the body. Unlike many other medical imaging techniques, endoscopes are inserted directly into the organ. There are many types of endoscopies. Depending on the site in the body and type of procedure, an endoscopy may be performed by either a doctor or a surgeon. A patient may be fully conscious or anaesthetised during the procedure. Most often, the term ''endoscopy'' is used to refer to an examination of the upper part of the gastrointestinal tract, known as an esophagogastroduodenoscopy. For nonmedical use, similar instruments are called borescopes. History Adolf Kussmaul was fascinated by sword swallowers who would insert a sword down their throat without gagging. This drew inspiration to insert a camera, the next problem to solve was how to insert a source of light, as they were still relying on candles and ...
