Esophagus «Barrett» Barrett's esophagus is a condition where damage occurs in the lining of the bottom of the esophagus, may lead to changes lead to cancer.
Among the 10 million Americans suffer from gastric juice reflux GERD, there is a million infected B 'Barrett's esophagus'.
Among those living with 'Barrett's esophagus' There is only a small percentage appears to have cancer of the lining of the esophagus esophageal adenocarcinoma, which is a deadly type of cancer.
Monitors doctors 'Barrett's esophagus' detects changes that occur before the emergence of cancerous tumors, by Nador (which is which to examine the esophagus tube, a light source, is inserted through the throat), and also draw a biopsy of the esophagus.
When cells are found suspicious, the usual treatment is surgery to remove the damaged part of the esophagus.
Treatment of radio waves,
but the process intrusive surgery and its risks, and therefore has developed many non-intrusive ways. According to a study published on May 28, 2009 in the magazine «New England Journal of Medicine», one of the treatments labeled «removal microwave radio» (radiofrequency ablation RFA) able to eliminate «esophagus Barrett», thus reducing the risk of cancer, and accompany only experience side effects simple .
This method works to destroy abnormal cells radio waves card.
In experiments conducted in a number of centers under the supervision of researchers from the Faculty of Medicine at the University of North Carolina, 127 people were exposed patients 'Barrett's esophagus' in a random manner, either to the radio waves or to «the waves and fake.
And implement a method of treatment of radio waves after making a mild anesthetic to the patient in the clinic.
This method was developed company «Parks Medical Corp., which itself has funded the study.
In this way, enter into the esophagus contain files catheter is inflated electromagnetic near the areas where they found the abnormal cells.
The energy flowing through radio waves to burn those files completely cells, without prejudice to the healthy tissue cells. In the case of 'phantom waves' did not send any radio waves after the introduction of the catheter into the esopThe participants were followed up after treatment for one year, during which he took them to be studied biopsies. And appeared to be «esophagus Barrett» has been removed completely after using the method of removal microwave radio with 97.5 per cent of those who were infected cases of mild disease which have changes light in the cells of the esophagus, compared with 22.7 per cent of those who were subjected to «waves fake».
The participants with severe deformities Mobiles which changes at most lead to the occurrence of cancer, 'Barrett's esophagus' still completely in 81 per cent of people exposed to radio waves, compared to 19 per cent for those who have been subjected to «fake waves.
The side effects of the removal method of radio-wave light, including chest pain were treated with drugs. The back has a narrow five of the participants in the esophagus, and were treated successfully after using the drugs to expand esophagus Bnazawr.
As noted by the supervisors of the study, they were small and the follow-up period was short (one year).
It also did not compare between the method of removal of magnetic waves and other non-surgical methods, such as photosynthesis dynamic therapy (treatment of tissue with light-sensitive drugs and then exposing it to him), and treatment freeze cryotherapy, and other ways in which employs a laser.
Other studies have assumed that these methods may be less effective, and in some cases they cause strong side effects.
However, subsequent studies seems important to determine whether the removal method was able to radio waves become the new standard method for the treatment of 'Barrett's esophagus'.
The people living with 'Barrett's esophagus' are threatened more by 30 to 40 times the risk of cancer of the lining of the esophagus.
This is, however, important to remember that cancer does not appear in 98 per cent of them.
'Barrett's esophagus' .. Changes in the cells lining
the disease «Barrett's esophagus, the type of cells similar to intestinal cells in a phenomenon called 'intestinal dysplasia» intestinal metaplasia (transformation type of fabric to another fabric editor) replacing the normal cells that line the lower part of the esophagus .
The problem occurs usually in the area of the confluence of the stomach , then stretch the area to the top distance may sometimes up to 3 inches (7.5 cm approx).
And be detected case Bnazawr after inserted through the mouth. And red seem affected tissue, similar to the color of the lining of the stomach, while the color of the normal lining of the esophagus and either pink or white lackluster.
Since it may be natural to stomach tissue growth at the bottom of the esophagus and the color red, the tissue biopsy is also necessary to confirm the diagnosis.
In the process of elimination of radio waves affected tissue is destroyed because of the disease «Barrett's esophagus is a result of short bursts of energy intensive radio waves through the device files electromagnetic envelope that has been inserted into the esophagus.
