What is Colonoscopy for Intestinal Video Made For?



What sensations can be expected during a colonoscopy?

To replenish the fluid, the patient is given intravenous infusions of solutions of electrolytes and glucose. The patient is placed on a special couch, connect the monitor to change blood pressure and heart rate, and determine the saturation of arterial blood with oxygen. Before the test or directly during the onset to reduce discomfort and pain syndrome The patient is administered intravenously or intramuscularly sedatives, after which a moderate drowsiness. With insufficient sedation, additional sedation can be administered up to a condition called medical sleep in practice. During the colonoscopy, the patient can feel a feeling of pressure, spasms and bloating in the abdomen, pain during the study rarely occurs.

The patient is usually asked to sit on his left side, rarely on his back. The area of ​​the anus to reduce discomfort and pain can be treated with anesthetic spray (anesthetic), after which The colonoscope is inserted into the lumen of the intestine and neatly advanced in the direction of its initial section, the part of the large intestine called blind gut. As soon as the tip of the endoscope reaches the cecum, the colonoscope is slowly withdrawn from the intestine, producing a visual sequential evaluation of the colon as it progresses. The procedure usually takes from 15 minutes to 1 hour. If, however, the colonoscopy does not, for various reasons, give a clear and complete picture of the condition of the colon, the endoscopist may recommend a second study after a preliminary preparation or the use of alternative methods for diagnosing intestinal pathology, for example, radiography with contrasted barium intestine or computer tomography.

What additional procedures can be performed during colonoscopy in detecting the pathology of the large intestine?

The most common procedure that is performed during a colonoscopy is a biopsy. Its essence lies in the fact that through a special channel in the endoscope to the place of interest (for example, a polyp) special forceps are brought in, which "bite" a small piece of mucous or polyp tissue. Subsequently, the structure of the resulting tissue is evaluated under a microscope under laboratory conditions.

If a pathologically altered mucosal biopsy is suspected for an infectious origin, a biopsy can be performed with the purpose of the subsequent cultivation of a microorganism, a bacterium or a virus, or a microscopic determination parasite. If the indication for colonoscopy is intestinal bleeding, it allows you to find the source of bleeding, determine the cause of this bleeding (eg, trauma to the polyp or ulceration of the mucosa in colon cancer, erosive colitis), perform therapeutic measures to stop bleeding. At present, the detection of polyps in the large intestine is an indispensable indication for their removal and biopsy, because this is one of the most effective ways to prevent the development of colon cancer guts. It is important to note that any of the additional procedures performed are often absolutely painless and not necessary, if a biopsy is performed, it is performed because of oncologic alertness.

What happens after a colonoscopy?

After the study, the patient is observed for 1-2 hours, until the symptoms associated with the use of sedatives are reduced. When using sedatives, the patient will remain drowsy for a while, his reaction, attention and coordination of movements will be reduced. That is why patients on the eve of the study are recommended to organize transportation home after the study and categorically prohibit driving. The patient may also have feelings of spasms or swelling of the intestines, which is often due to the fact that in the lumen of the large intestine retains the air introduced into the gut for its spreading and better visual evaluation of the wall guts. Over time, these uncomfortable phenomena will disappear, and gas will escape from the gut. After removing polyps or other medical-diagnostic procedures, it is recommended that some time be refrained from taking rough food.

The results of a colonoscopy usually become known already during the study, although in cases where a biopsy is performed mucous, the final conclusion is given after microscopic examination of the tissue sample 2-3 days after the sampling biopsy.

What complications are possible during and after a colonoscopy and is there an alternative to a colonoscopy?

The complications during the study are rare and more often due to the fact that such a study is conducted by not sufficiently experienced and competent doctors.

One of the most frequent complications of the study is intestinal bleeding and it occurs mainly after biopsy or removal of polyps of the large intestine. In most cases, bleeding stops on its own, looks like a small streak of blood in the stool and rarely requires a repeat colonoscopy. With the retention of repeated blood flows, repeated procedure allows to stop bleeding, and serious bleeding, requiring blood transfusion or performing surgical intervention are currently casuistry. Less common are complications such as perforation (formation of a "hole perforation) of the intestinal wall or rupture of the mucosa.

Among other potential complications, there are reactions to sedative drugs, inflammation of the vein, through which Drugs (eg, thrombophlebitis of the cubital vein) or complications of existing heart diseases and lungs. In total, the complication rate after colonoscopy is less than 1%, and the bulk of these complications is not life-threatening.

Despite the rare occurrence of such complications, it is important that the doctor and the patient retained which will allow early detection of complications and prompt treatment for help. The endoscopist who conducted the tests, the patient should notify the doctor if he noted the appearance of abdominal pain, signs of continued rectal bleeding. fever and chills.

In modern medicine, a colonoscopy is the best method of diagnosis, diagnose and conduct timely treatment of pathological changes detected in the primary departments the colon. In contrast to the radiographic study of the intestine with barium (the method of investigation is called irrigoscopy), it allows to make a biopsy and therapeutic measures on the intestine, therefore at present, alternatives to this research on there are no opportunities. If suspicion of the pathology of the lower parts of the colon - sigmoid and rectum, sigmoscopy can be used as a diagnostic test. but with its use, the volume of the study is limited to the lower part of the large intestine.

What is colonoscopy of the intestine and how is it performed?

Colonoscopy is a test in which a special medical instrument is used to examine the inner surface of the intestine. This method of diagnosis is safe and informative, as it allows to identify at an early stage of the disease of the digestive tract. Colonoscopy is also used for surgical intervention.

Colonoscopy of the intestine is done by introducing a flexible probe (colonoscope) into the large intestine, which is equipped with a small chamber and forceps to take the material. The camcorder surveys in real time, illuminating the areas along the path of the probe. The coloproctologist can look at the mucosa due to the transmitted video and see the microscopic changes with pathological deviations. Such examination of the intestine is highly informative. Testimonials confirming the effectiveness of a colonoscopy, you can find in this article.

1. visual assessment of the mucosa and intestinal motility;

2. detection of inflammatory processes;

3. clarification of the diameter of the lumen of the large intestine and widening of the narrowed sections;

4. detection of pathological neoplasms;

5. during the survey, the materials are taken for further analysis;

6. if benign formations are found, they are removed immediately;

7. detection of internal bleeding and their elimination due to exposure to high temperature;

8. photo and video.

The probe probe allows the doctor to get a complete clinical picture of the intestine. Colonoscopy is done in many medical institutions, both public and private. Experts recommend conducting preventive examination of patients for 40 once in 5 years. In chronic diseases of the intestine or exacerbation of the process, the procedure is prescribed without fail.

There are three varieties:

Each of the types of examination of the intestine is done with a probe, but there are differences.

1. First, you need to understand what a virtual colonoscopy is. This medical research has spread relatively recently. As with the traditional method, a visual review of the intestine is carried out, where the picture is transferred to the monitor.

Preparation for a virtual procedure is identical to conventional intestinal diagnostics. A study is carried out by introducing a probe into the large intestine, which fills the air with the intestine. Thus, this kind brings a minimum of discomfort, and the data obtained are informative. The disadvantages are the high price, the lack of the opportunity to take the material for a biopsy and the uncomfortable sensations. However, even after a normal colonoscopy, the patient may have pain syndrome.

2. Preventive examination can detect cancerous tumors in the intestines, from which hundreds of people die each year in the world. Cancer, unlike other forms, is sluggish and at an early stage lends itself to healing. The risk group includes those people in whose family were patients with a characteristic disease. Only a colonoscopy can detect a dangerous disease at an early stage, because Cancer at first does not cause symptoms.

Indications and limitations

Experts recommend that such a survey be done at the following signs:

  • a chair of black color;
  • there is blood;
  • systematic diarrhea;
  • severe weight loss;
  • colitis;
  • pathology of the colon;
  • polyps;
  • chronic pain.

The study is conducted with suspicion of colon diseases. Sometimes experts prescribe an X-ray, but if the primary examination reveals the symptoms of a tumor, then recommend a colonoscopy. Despite the fact that it is not traumatic and safe, some patients are prohibited, since there is a risk of complications or contraindications. However, it is done if there are no other methods to solve the problem.

Disease of the digestive system requires careful examination, including.

Diseases of the gastrointestinal tract, inflammation of the digestive organs take first place in.

Sensing the stomach as a method of examination is used to identify a number of gastrointestinal diseases. Modern methods.

The purpose of our site is, first of all, to educate readers in the field of gastroenterology. We want to protect you from possible errors that occur during self-treatment, help to recognize the onset of diseases. This in no way eliminates the need for specialist advice and the establishment of an accurate diagnosis. To treat the patient in accordance with his individual characteristics and monitor the course of the disease should only the doctor!


Colonoscopy of the intestine

Diet with a colonoscopy is mandatory. Conducting a colonoscopy is possible not earlier than 4 hours after the last reception of the drug. Preparation is carried out both on the eve of the colonoscopy, and on the day of the study. How is a colonoscopy done in such cases?

In many countries this research is performed by the coloproctologist, in Russia it is carried out by an endoscopist, which makes the use of the colonoscopy even more informative. Each coloproctological patient should perform a colonoscopy for polyps of the rectum and, especially, for cancer of the distal parts of the large intestine, which are found during sigmoidoscopy.

Sometimes an X-ray examination of the large intestine is performed before colonoscopy - irrigoscopy. Colonoscopy is a rather complicated procedure, so try to help the doctor and nurse as much as possible - follow their instructions. During a colonoscopy, you will have a feeling of gullet overflow, which causes the urge to defecate. In addition, at the time of overcoming the bends of the intestinal loops, there is a displacement of the intestine.

Colonoscopy of the intestine

The success and informative nature of the study is determined mainly by the quality of the preparation for the procedure, so pay serious attention to the implementation of the recommendations below.

Preparation for endoscopic or X-ray examination of the colon, as well as for surgical interventions requiring the absence of contents in the intestine. It is clear that the metal tool will not be able to follow the intestines and, in the worst case, just break through its walls.

Preparation for the study in this case is of particular importance. After all, the better the intestine is cleared, the more information it will be possible to get during the diagnostic procedure. Purification of the intestine can be carried out both with the help of special drugs, and with the help of conventional enemas. The procedure itself takes no more than 20 minutes and is conducted in a special office.

After performing a colonoscopy, you do not need to follow any special diet - you can eat normally after the procedure. Perhaps a sense of "bursting" of the intestine because of the air introduced during the study. And that is why she is preferred by coloproctologists, when a colon examination is necessary.

In all these cases, the patient's health is too high, so colonoscopy is replaced by alternative methods. Also on the eve of the examination you need to empty the intestine.

The use of special laxatives makes the procedure for preparing the intestine for the examination more comfortable for the patient. And so throughout the large intestine (see how the procedure is performed - the video on the same page). How do colonoscopy - with or without pain relief? The examination, as a rule, does not cause the patient expressed pain, therefore, without anesthesia.

On this page you can see how the colonoscopy is done - the video demonstrates this very clearly. In children, patients with adhesive disease of the abdominal cavity and with pronounced destructive processes in the large intestine, the procedure can be very painful.

Does the colonoscopy hurt? Is anesthesia used in a colonoscopy?

After the examination, the patient returns to his usual life. You can eat and drink after the procedure immediately, and the food after the colonoscopy does not require any restrictions. Air, which was pumped into the intestines during the examination, is sucked off by a colonoscope. Against the background of other methods colonoscopy of the large intestine provides the proctologist much more diagnostic capabilities.

For the examination of the intestine, there are many procedures. Such a study is the insertion of a special probe into the patient's intestine through the anal passage. This diet will help cleanse the toxins and will not have time to get bored, since it is carried out for 2 to 3 days before the colonoscopy.

From the evening the intestines are cleaned twice - at an interval of 1 hour. The appropriate time for cleaning is 20: 00 and 2: 0 or 1: 0 and 2: 0, respectively. This drug does not interfere with the medical intervention, as it is specially designed for endoscopic procedures and X-ray examinations. Another tool that will help prepare your body and, in particular, the intestines, is Dufalac.

First of all, it should be performed with suspicion of a tumor, in these cases its resolution is much higher than the irrigoscopy. Patients with severe pain in the anus are shown local anesthesia (dicaine ointment, xylocaine).

The technique of colonoscopy is quite simple. Colonoscopy, like any other study is not appointed from the "Bay of Barahta." Colonoscopy - the video can be viewed below - this is an endoscopic method of examination of the large intestine. As you can see, the possibilities of colonoscopy are truly unique. Of all the examination methods used in coloproctology, colonoscopy of the intestine deserves special attention. Emergency colonoscopy for patients with intestinal obstruction and bleeding can be done without preparation.
