Today, bowel cancer has become one of the most common types of oncology, not only in Russia, but throughout the world.
The reasons are in ecology, and in malnutrition, and in a deficiency of fiber in food.
However, a timely detected disease or its predecessors (intestinal polyps) is treatable. If the diagnosis is made at an early stage, modern technology can save more than 90% of patients.
Doctors call the screening colonoscopic examination the gold standard for the diagnosis of colorectal cancer, which after 50 years is recommended for people to do every two years (and if there are risk factors every year starting from 40 years). In the course of its implementation, two tasks are solved at once: diagnostics are carried out and polyps are removed, which can subsequently be reborn, if any.
Doctors say that if all people of the appropriate age did a colonoscopy regularly, then colon cancer would be extremely rare. This is exactly what the Japanese are doing with respect to the colonoscopy procedure. Therefore, in this distant country, the number of patients with cancer of the intestine is several times smaller than ours.
But for now, alas, not so. In our country, 47 thousand new cases of colorectal cancer are detected every year. The main risk group is people over 60 years old.
Many are afraid to undergo a colonoscopy, because it is painful, painful, and for some the process itself also seems humiliating. However, a new, more comfortable version of this study began to be introduced in our medical institutions – with the help of a video capsule, which is swallowed inside.
According to Ekaterina Tikhomirova, an endoscopist at City Clinical Hospital No. 17, video capsule colonoscopy (VCC) is painless, effective, there is no need for anesthesia and gas supply, there is no radiation exposure, and there are no side effects.
There are two miniature video cameras at both poles of the capsule; they take from 4 to 35 shots per second, depending on the speed of movement of the capsule in the intestine.
The colon capsule has a wider viewing angle than the small intestinal capsule (172 degrees from each camera) and an increased depth of field (40 mm). This allows you to identify even the smallest polyps of the colon, often skipped during traditional colonoscopy.
The sensitivity of VCC in the diagnosis of colon neoplasms from 6 to 9 mm in size is 89%, and for formations with a size of 10 mm or more – 88%.
An important advantage of VCC is the ability to diagnose diseases of not only the colon, but also the small intestine. This is especially true for patients who suspect Crohn's disease, often affecting various segments of the small and large intestine. VKK will allow you to assess the condition of the mucous membrane of the small and large intestine during the initial examination and report on how successful the treatment is.
However, if the video capsule detects a problem, then you still have to do a classic colonoscopy (at least in order to take fragments for a biopsy or remove polyps). But then you will be absolutely sure that this unpleasant procedure is worth suffering – it is really necessary.
Now scientists are working to make the capsule manageable, like on a computer console with a joystick. Then the capsule can replace traditional colonoscopy.
A new type of diagnosis is already available in a number of city hospitals in the capital and the Russian Federation.
