This endoscopic examination is carried outUsing a special device, called rectoscope. It allows you to give a visual assessment of the inner surface of the intestine from the anus at a distance of 30 cm. The device is similar to the inside of the hollow tube having a small diameter, it is made of metal and equipped with optics. After entering the device into the rectum through the anus proctologist (or endoscopist) is an opportunity to inspect the intestinal mucosa, and capturing more of the sigmoid. Endoscopist certainly draws attention to the elasticity, color, moisture, shine and relief pattern, folds of mucous membrane, making conclusions about the state of vessels, tone and motor activity surveyed intestine. If you suddenly will be seen neoplasm, the specialist pinch off a small portion of it, then to carry out histological analysis.
When shown the procedure?
If the intestines clogged stool, it will complicate the introduction into the anus proctoscope, inspection will be impossible to carry out. endoscopist Work complicated if the patient has recently conducted irrigoscopy and residual barium is present. In order for the examination to be effective, it helps to identify the causes of the ailment, you need to prepare accordingly. Long before the procedure, the doctor should explain to the patient that to examine the intestinal mucosa of the intestines, it will be necessary to resort to a rectoscope, which will have to be inserted through the anus. The proctologist clarifies whether the patient has allergies, what medicines he uses, and whether he was examined in the last seven days of the gastrointestinal tract with radiopaque barium. Then the doctor will explain to the patient that on the eve of the procedure (24-48 hours) he will need to follow a diet, clean his intestines. At this time, vegetables and fruits are excluded from consumption, an indication is given - to drink more. On the day preceding the procedure, dinner should be skipped, replacing it with a cup of tea. Most proctologists are inclined to believe that the procedure should be prescribed for the morning hours, so that it is done on an empty stomach. In some cases, it may be recommended 3 hours before the procedure (or in the evening) to perform a cleansing enema, for which you need to use ordinary water and a Esmarch mug. our site warns that it is not necessary to use soapy water for such purposes. Sometimes they resort to cleaning the intestinal tract with the help of laxatives. Among them - Duphalac, Normase, Fleet, Fortrans. The patient is warned before the procedure that before the introduction of proctoscope is lubricated so it is best moved by the rectum, so many have false urge to defecate. Even during the movement of the endoscope gut is slightly expanded, it often causes colic. To straighten the intestinal mucosa, in the rectum air will be supplied. If the patient feels that the gases want to get from the intestines, then it should not interfere with this. If you have a chronic inflammation in the rectum, then 20 minutes before introducing it proctoscope will be treated with a solution of local anesthetic drug.
It is undergoing tests in the clinic orhospital, its duration - approximately 20 minutes. First you need to remove all clothing from the waist down. Typically, the patient shall be issued a special one-off shorts made for the study.

If the patient is on the left side, then under his left thigh enclose cushion or small pillow sizes. The doctor gently removes the right buttock to the side, examining the anus. This is followed by palpation (examination with the fingers proctologist) the anus and rectum. It recommended at this moment to breathe through the mouth, quietly and deeply. After removing the proctologist finger mark whether the feces are present, allocation (pus, mucus or blood-tinged). The tube of the endoscope with an obturator inserted therein smeared with vaseline or a gel slowly introduced 5 cm into the anus. Then the obturator is replaced by the eyepiece, then the device again continues its slow movement on the rectum. When he passes the anal valve, it is necessary to natuzhitsya, as occurs in bowel movement. To bowel folds dealt, there is a supply of air in the digestive apparatus. If further examination prevent fecal matter, the eyepiece will be removed, and his place will replace the cotton swab necessary to clean the intestinal lumen. Interfering mucus, blood is removed using electric pump. If you need to remove the growths polypous then injected coagulation loop. When the inspection is completed, all the samples of biological material taken (from inflammatory sites or tumors), the device gradually pulled out. The biomaterial is preserved in a special way, it is placed in the appropriate container. To avoid falling blood pressure, a few minutes the patient is better to lie down on his back. Some time after the treatment of intestinal gases will be released. mymedinform.com warns that if a biopsy was taken, the feces in the first days will be visible blood veins, do not be afraid of this.
Skilful endoscopist actions do not cause painpatient. The discomfort may occur, but it is connected with the fact that while in the intestine there is air procedures. Pain and if there are, then the tolerant, do not require the introduction of anesthetics. Under anesthesia, the survey only do young children.
