Colonoscopy
– an endoscopic method for examining the inner surface of the intestine using a special device – a colonoscope. The flexibility and softness of the thin probe allows it to painlessly pass through all anatomical curves of organs, identifying various pathologies with high accuracy. The length of the device, equipped with a miniature video camera and lighting, is approximately 160 cm. The image is instantly transmitted to the monitor screen in multiple magnification. Thanks to this, the specialist can examine in detail the inner surface of the area under study, identify foci of inflammation and the nature of changes in the mucous membranes.
Indications for colonoscopy
Colonoscopy is prescribed in the following cases:
- frequent pain in the intestinal area
- bleeding
- purulent or mucous discharge from the rectal canal
- suspicion of inflammatory processes
- sudden, causeless weight loss
- the presence of cancer in the gastrointestinal tract in close relatives
- remove tumor or polyp
- remove foreign body
- stop the bleeding
- do a biopsy
- restore intestinal patency during narrowing (stenosis)
- eliminate adhesions
- identify the nature of hemorrhoids
Colonoscopy can be used to perform a number of medical procedures:
A referral for a colonoscopy is issued by a proctologist, gastroenterologist, or surgeon. The procedure itself is performed by an endoscopist. During the manipulation, he is assisted by a nurse and an anesthesiologist (if there is a need for general anesthesia).

Preparing for a colonoscopy
An examination of the intestines requires careful preparation, so the decision on the need for it is made by the doctor based on a combination of clinical history and laboratory results, the current condition and age of the patient. If traditional colonoscopy is not possible, alternative methods are used.
The process of preparing for the procedure includes two stages - switching to a slag-free diet and cleansing the intestines. Three days before a colonoscopy, it is recommended to switch to a gentle diet, excluding fresh fruits and raw vegetables, cereals and pasta, brown bread, fried and smoked foods from the daily menu. It is advisable not to drink carbonated water, coffee and milk. They can cause severe fermentation in the intestines and bloating.
Allowed:
The next stage of preparation is intestinal cleansing.
For this purpose, special laxatives are used. The specialist prescribes a remedy suitable for each patient according to his individual indications.
Most used medications:
The mechanism of action of the drugs Fortrans and Endofalk is that they prevent the absorption of substances in the intestine. This leads to faster movement and evacuation of the contents (in the form of liquid stool) of the gastrointestinal tract. Due to the content of electrolyte salts in laxative preparations, disruption of the body's water-salt balance is prevented (dehydration does not occur, as with ordinary diarrhea).
The action of the drugs Fleet Phosphosoda and Lavacol is based on a delay in the excretion of water from the intestines, which causes an increase and softening of feces, increases peristalsis and leads to rapid emptying.
Another way to cleanse the body is a traditional enema. The procedure is carried out several times using 1.5 liters of clean water.
It is important to remember that on the eve of a colonoscopy, it is advisable to skip dinner, and on the morning of the procedure, you should not have breakfast.
Diet before colonoscopy
Before a colonoscopy you can eat:
- Boiled or steamed meat: chicken, fish, lean beef.
- Low-fat broth;
- Eggs;
- Boiled sausage;
- Cheese;
- Fermented milk products without additives (kefir, fermented baked milk);
- Unsweetened cookies;
- White bread.
Before a colonoscopy you should not eat:
- Legumes (beans, peas, soybeans, lentils);
- Vegetables (potatoes, cabbage, radishes, radishes, beets, carrots, turnips, garlic, onions);
- Sorrel and spinach;
- Fruits (apricots, plums, peaches, pears, dates, bananas, oranges, tangerines, raisins, grapes);
- Nuts and berries (currants, gooseberries, raspberries);
- Brown bread (including grain bread);
- Porridges made from pearl barley, millet, buckwheat and oatmeal.
Before a colonoscopy you should not drink:
- Milk;
- Alcohol;
- Carbonated drinks.
Performing a colonoscopy
Given the possible discomfort during manipulation, the procedure requires mandatory anesthesia. There are several options for pain relief during a colonoscopy. This is local anesthesia (treatment with ice-caine, luan gel, dicaine ointment, etc.), sedation (introduction to light medicated sleep) and general anesthesia. Local anesthesia is most often used. It allows you to communicate with the patient, thereby freely controlling the progress of the entire procedure.
A colonoscopy examination is carried out in a separate room at a medical institution. The patient changes into a special robe and lies on the couch on his side with his knees bent. After antiseptic treatment, the doctor carefully inserts a colonoscope into the anus, sequentially examining the intestinal walls. First, the area of the lower parts of the gastrointestinal tract is examined, then the condition of the sigmoid and cecum, as well as part of the small intestine, is assessed. A small amount of gas is injected to expand the lumen of the intestinal tube. In this case, the patient may be bothered by slight bloating. At the end of the examination, excess air is removed and the feeling of bloating disappears. A typical diagnostic procedure lasts approximately 15-20 minutes. If there is a need for urgent surgery, the time may be increased. After the colonoscopy is completed, the device is carefully removed from the intestine and sent for disinfection. The patient is advised to take a short rest and return home.
When can I get my colonoscopy results?
A description of the intestinal condition can be obtained a couple of days after the procedure. If a biopsy was performed during colonoscopy, the time period increases until the histological examination data is obtained. In the conclusion, the compliance of the patient’s intestinal tube with certain criteria is indicated, as well as additional manipulations performed (if any). In addition to documents, you will be given a disc with a photograph or a reproduction of the colonoscopy process. Patients pass on the information received to the attending physician to determine further tactics for patient management.
Rehabilitation
After a colonoscopy, a hospital stay is not expected; the patient leaves the hospital. Drugs administered for anesthesia are eliminated from the body within several hours. For the first half hour or hour, sudden movements should be avoided, and the feeling of fullness in the intestines is a normal possible reaction, it passes quickly.
Side effects of colonoscopy
Colonoscopy usually goes without consequences. Serious complications occur very rarely. Most often they are associated with the doctor’s lack of experience in performing such endoscopic manipulations. Possible risks include:
What can be revealed
FCS with anesthesia allows you to:
- carry out differential diagnosis between chronic diseases with colitis syndrome;
- identify diverticula;
- detect polyps and other benign neoplasms and remove them endoscopically;
- detect malignant tumors (cancer) of any form at the earliest stages, when they are still small in size and limited to the mucous membrane and submucosal layer.
At the moment, FCS is the most informative, reliable and safe way to assess the condition of the wall of the large intestine and identify any neoplasms located here.
Recovery after colonoscopy
Side effects of the procedure are discomfort as a result of the injection of air into the intestines during the examination, pain due to involuntary contractions of smooth muscles as the probe passes further than 15 centimeters. Proper rehabilitation will help the patient overcome all this - daily routine, dietary nutrition, medications that eliminate discomfort in the stomach and intestines.
The menu during this period is formed taking into account possible injury to the intestinal walls, especially if the examination was accompanied by the removal of tumors or the collection of biomaterial. Basic nutrition rules:
Among the permitted products: lean meats and fish, heat-treated vegetables, light broths, dairy products (low-fat cottage cheese, yogurt, kefir), lightly dried whole grain bread, eggs in the form of a steam omelet, savory cookies, fruit drinks, compotes, jelly. Method of preparation: boiling or stewing. It is advisable not to consume fresh fruits on the first day after a colonoscopy. It is forbidden to drink strong tea or coffee, carbonated drinks, alcohol, or freshly squeezed juices. Long-term dietary restrictions after colonoscopy are not required. 2-3 days are enough.
To reduce intestinal colic after the study, on the recommendation of a doctor, you can take sorbents and antispasmodics. To eliminate pain in the anus, it is advisable to use rectal suppositories or ointments that are used for hemorrhoids. If abdominal discomfort, diarrhea or constipation, bleeding from the anus and other disorders continue for more than 2-3 days, you should definitely consult a specialist! It is necessary to carefully monitor the condition of your body.
Colonoscopy
- a modern diagnostic method that will not only establish, but also eliminate the cause of pathological symptoms of the digestive tract. If you are regularly bothered by intestinal problems, do not delay visiting your doctor. Don't self-medicate!

Is it possible to replace the FCC with something?
As an alternative, FCS often offers irrigoscopy and CT. In fact, these techniques cannot fully replace endoscopic examination. They do not allow a detailed and targeted examination of the tumor, do not detect small defects in the mucous membrane and do not allow a biopsy. In addition, these techniques involve the use of radiation, which imposes certain restrictions on the timing of re-diagnosis.
Fibercolonoscopy is the optimal method for assessing the condition of the walls of the large intestine and the most informative way for the early detection of colorectal cancer.
Unfortunately, more than 1/3 of malignant colon tumors are diagnosed at late stages, which explains the high mortality rate from this disease. In many cases, this is due to patients’ unreasonable refusal of recommended regularly repeated endoscopy. The lack of information content and reliability of screening studies carried out in clinics, with preference for laboratory or X-ray diagnostics, is also of certain importance.
