Endoscopy - diagnostics of internal organs with the help of special devices - endoscopes.
Methods of endoscopy is that through the openings in the human body soft tube is introduced at the end of which the lighting apparatus and attached microchamber. This tube is called an endoscope. Its diameter is not more than 4 mm.
For different areas of medicine are different endoscopes. Endoscopy of the stomach, upper digestive tract, 12 duodenal ulcer, are gastroduodenoscopy for examination of the small intestine using enteroscopy, endoscopic intestinal apply colonoscopy for airway use bronchoscopes.
With some manipulation endoscope is inserted through the mouth (endoscopy of the stomach), and others through the rectum (bowel endoscopy), through the larynx, urethra, and nose (nasal endoscopy). To carry out, for example, laparoscopy, abdominal special openings have to travel.
There are many types of endoscopy. With this procedure, you can examine the state of vital organs such as the abdominal cavity, the vagina, a thin and 12 duodenal ulcer, ureters, bile ducts, esophagus, hearing, bronchi, uterus, and also to make an endoscopy of the stomach, intestinal endoscopy, endoscopy nasopharynx.
The endoscope can be passed through blood vessels to check their status, and view the heart and the heart chambers. In this age of the endoscope can even get into the brain and allow the doctor to view the ventricles of the brain.
All types of endoscopic examinations are intended to detect minimal changes in the mucosa, which can then lead to cancer. This procedure also makes it possible to identify at an early stage oncology and remove the tumor, which greatly increases the chances of survival of cancer patients.
Cancer in the early stages is impossible to identify with another study, so that today there is no alternative to endoscopy.
In addition to diagnostic, this procedure has been widely used in surgery, urology, gynecology and other fields. With its help, doctors stopped the bleeding, remove tumors in the early stages. The procedure allows not only to diagnose the internal organs, but also take a sample of tissue tumors for analysis.
The technique is also widely applied in plastic surgery, for example, endoscopy forehead and eyebrows. Endoscopy allows forehead raise eyebrows, to remove or reduce the amount of facial wrinkles on the forehead and between the eyebrows. Endoscopy forehead is very popular due to the fact that leaves little scarring.
How is the procedure of endoscopy
In gastric endoscopy apparatus is administered orally and the mucosa inspected monitor. This is done through an endoscope air supply - it is necessary for a more detailed examination. The procedure lasts about 15-20 minutes.
To study more accurate, it is necessary to properly prepare. For 8-12 hours before the procedure, it is desirable not to eat or drink.
Gastroscopy - a painful investigation, causing a gag reflex in a patient.
Transnasal endoscopy tolerated much easier, as the gag reflex when it is absent.
Endoscopy of the stomach makes for diagnosis and detection of changes.
Intestinal endoscopy - a painful and prolonged occupation. Pain can be caused by the peculiarities of bowel adhesions. The actual procedure takes from 30 minutes to 1 hour. Often during colonoscopy using anesthesia.
During the colonoscopy preparation is just as important. It is recommended that three days before the procedure, go to bezshlakovuyu diet.
The indications for colonoscopy are violations of the chair, mucus and blood, pain, bleeding from the colon.
Bronchoscopy is performed by introducing a thin endoscope through the nose, throat and vocal cords directly into the trachea. This allows you to inspect the inside of the bronchial tree. Studies have shown with pneumonia, bronchitis, suspected tumor.
When nasal endoscopy the endoscope is introduced into the nose, which allows you to see the picture of the inside of the nose and possible polyps. Endoscopy is indicated for nasal breathing difficulties, nosebleeds, violation of smell, with polyps and obscure headaches.
Nasal endoscopy reveals pathological changes in the nasal mucosa without surgical intervention.
This type is a new trend in medicine. It is a method that the patient swallows a plastic capsule, which is not bigger than a normal capsules. The capsule extends all the digestive organs, and the entire image is recorded on a special unit, and it, in turn, transmits the data to the screen.
Videokapsulnaya endoscopy was patented in America in the beginning of this century, and rapidly gaining momentum. The capsule itself weighs 4 oz., And its length is 2, 5 cm. One end of the capsule at the transparent lens is hidden behind it, microchamber and LEDs. The rest of the capsule are the transmitter, battery and antenna.
Videokapsulnaya endoscopy is very useful, as it allows no separation from the main activities of the patient to hold a full endoscopy of the stomach, intestinal endoscopy and gastrointestinal tract. In addition, such research allows us to see even those sections of the intestine that are not available in conventional endoscopy.
However videokapsulnoy endoscopy has one major drawback. Unfortunately, using this method can only be done a study of the digestive system.
