Colon cancer has recently taken third place in the structure of overall mortality from cancer. Conducted scientific research convincingly proves that early diagnosis can significantly increase the effectiveness of subsequent treatment Colonoscopy is a highly informative endoscopic examination, during which the condition of the large intestine and even the terminal part of the small intestine is visually assessed. If necessary, the examination can be supplemented by taking samples of identified pathologically changed areas of the intestine for subsequent examination under a microscope (biopsy).
Carrying out a colonoscopy under anesthesia
A few days before the procedure, you need to give up fatty foods and foods that cause increased gas formation - legumes, rye bread, carbonated drinks. Then you need to take a laxative and drink plenty of water at night. Your doctor may recommend an enema.
FCS under anesthesia is performed under the supervision of an anesthesiologist and lasts from 15 to 30 minutes. During this time, the doctor will examine the intestinal mucosa and, if necessary, perform a biopsy or remove polyps.
After the procedure is completed, the anesthesiologist will wake up the patient, and within half an hour you can go home. The FCC does not require hospital stay under anesthesia.

There are different methods and equipment for diagnosing diseases of internal organs. One of the most important areas is intestinal research. Many people are interested in the question of why a colonoscopy is needed and what it does.
What is a colonoscopy?
Colonoscopy or fibrocolonoscopy refers to endoscopic diagnostic methods and is aimed at examining the lower parts of the intestine - the rectum and colon. It is provided using a special device (colonoscope) in the form of a thin, flexible tube with optical fiber, on which an examination camera or working instrument is attached, as well as a backlight.
The colonoscope is inserted into the intestine and gradually moves along the rectum. Along the way, the intestinal walls and the state of the lumen are examined. The entire procedure lasts from 20-25 minutes to 1 hour.
Why do a video colonoscopy?
Colonoscopy allows you to visually examine the intestines and take biological samples (biopsy) for laboratory tests. The colonoscope can be equipped with a miniature surgical instrument for performing minor operations.
The considered method allows you to:
— Diagnosis of intestinal diseases, incl. inflammatory and tumoral in nature.
— Detection and study of internal intestinal bleeding, determination of their causes.
— Preoperative examination to assess the condition of the intestine and develop surgical tactics.
— Detection and removal of benign tumors.
A colonoscope helps to identify the smallest lesions, which is very important for diagnosing cancer at an early stage. With its help, foreign bodies are identified and removed.
When is a colonoscopy prescribed?
Colonoscopy allows you to diagnose the following intestinal pathologies:
— colitis of various types, including ordinary and ulcerative;
- Crohn's disease;
- presence of polyps in the colon;
- intestinal diverticulosis;
- Hirschsprung's disease;
— tumor pathologies of various etiologies, incl. malignant formations;
- peptic ulcer;
- intestinal obstruction.
The method provides identification of inflammatory processes and assessment of their degree.
Which doctor can refer you for the test?
Depending on the symptoms of the disease, doctors of different specializations can refer you for a colonoscopy:
- Therapist or gastroenterologist - for frequent pain in the intestines, chronic bowel dysfunction, detection of blood and other dangerous discharge in the stool.
- Proctologist. He most often prescribes a colonoscopy for hemorrhoids in a serious stage, identifying cracks in the rectum.
- Oncologist - at the slightest suspicion of the development of malignant tumors. A biopsy sample is taken using a colonoscope for laboratory testing.
- Hematologist - when blood counts indicate the possibility of hidden bleeding in the digestive organs.
Before intestinal surgery, a colonoscopy may be prescribed for a detailed examination of the lesion.
Preparation for the procedure and methodology
In order for the study to be as effective as possible, it is necessary to take the preparation for a colonoscopy responsibly. Therefore, you need to complete all the preparatory steps.
You should go on a diet at least 3 days before the procedure. The following should be excluded: brown bread, cereals, fresh vegetables and fruits, greens, cabbage in any form, legumes, peas, lentils, dried fruits, including raisins, berries and nuts, fatty dairy products (including cream, sour cream, ice cream , fatty cottage cheese), fatty fish and meats (including duck and goose), pickles, marinades, smoked foods, sweets, alcohol, carbonated drinks, kvass.
Allowed to eat: rice, pasta made from premium flour, white bread, boiled lean meat (veal, beef, chicken), cutlets, meatballs or soufflé, eggs, lean fish (cod, pike perch, perch, pike) , vegetable decoctions, potatoes (without peel), low-fat dairy products (cottage cheese, cheese, kefir, skim milk), honey.
The day before a colonoscopy, it is necessary to cleanse the intestines. This may be a cleansing enema or a drug recommended by a doctor.
What can replace a colonoscopy?
There are various methods for examining the intestines, but they cannot completely replace colonoscopy, which is recognized as the most informative diagnosis. In addition, a colonoscope can be used to perform minor surgeries and take biopsies. As a rule, the main way to diagnose intestinal conditions is colonoscopy, and other studies are prescribed as additional ones.
Additional tests that can complement colonoscopy:
— Magnetic resonance imaging (MRI). It cannot completely replace colonoscopy, because it is impossible to detect minor lesions.
— Computed tomography (CT of the intestine). This is the most realistic alternative to colonoscopy, providing the opportunity for a detailed examination. The downside is that it refers to x-ray methods, which means it carries a certain danger of radiation.
- Irrigoscopy - radiography using a contrast agent. The method is inferior in terms of information content to colonoscopy.
- Anoscopy. It provides a detailed examination of the rectum using the optical instrument of an anoscope, but its capabilities are limited to a distance of 12-15 cm from the anus.
— Sigmoidoscopy. A special optical device allows you to conduct research at a distance of up to 30 cm.
- Ultrasound. This is the most comfortable method, but it is inferior to colonoscopy in terms of its ability to identify small lesions and provide information.

How is a colonoscopy performed?
This is an invasive medical procedure that requires considerable experience and high qualifications from the doctor so as not to harm the patient. Therefore, a clinic where you can undergo a colonoscopy must have an excellent reputation and have specialists of the appropriate level on its staff.
The patient lies down on the couch, usually on his left side. The procedure begins after the administration of anesthesia: a long flexible medical probe is inserted into the anus and moved deep into the intestine. A camera attached to its tip transmits an image of the internal walls to the screen. If necessary, using a probe, the doctor can take a small sample of tissue for analysis, remove polyps, etc. The examination usually lasts no more than half an hour and does not cause any unpleasant consequences or pain.
Colonoscopy – is it painful or not?
Most patients' doubts about the need for a colonoscopy are based on fear of the painful sensations that they are expected to endure. Such different and contradictory reviews about the procedure are due to different pain thresholds and congenital structural features of the gastrointestinal tract.
The examination, as a rule, does not cause significant pain in the patient, and therefore is carried out without anesthesia. Some discomfort may occur when pumping air and passing the colonoscope through intestinal bends, for example, the hepatic and splenic angles of the colon. But these sensations are usually tolerable. If the patient is well prepared, the procedure usually lasts 15-20 minutes.
In patients with adhesive disease of the abdominal cavity, as well as those who have undergone extensive surgery on the abdominal and pelvic organs, the procedure can be very painful and lengthy. In such situations, the examination is carried out under anesthesia.
The endoscopist will inform you about the results of the study immediately after the examination, and when a biopsy is taken, the morphological report will be ready in 8–12 days
You can eat and drink immediately after the procedure, and nutrition after a colonoscopy does not require any restrictions. If the patient still has a feeling of bloating, you can take 10 tablets of activated carbon, previously crushed and dissolved in half a glass of warm water.
Contraindications to the procedure:
- acute myocardial infarction and decompensated cardiopulmonary failure
- stroke
- fulminant form of colitis
- acute infectious process of any localization
- acute diverticulitis
- aortic aneurysm
- tense ascites
85% of patients with colon cancer are over 60 years of age. According to the recommendation of the World Health Organization, a colonoscopy should be performed for every healthy person after 55 years of age once every 10 years. If there is an increased risk of the disease in the family (in first-degree relatives, especially if colon cancer developed in the patient before 45 years of age), the first preventive colonoscopy should be performed 10 years before the age at which cancer was detected in relatives. If certain complaints or indications appear, a colonoscopy should be performed immediately.
Preparing for a colonoscopy:
Comfortable colonoscopy
- Possibility to choose a doctor and examination time, adherence to the schedule
- Providing disposable diapers, napkins and disposable proctological panties
- Possibility of being in a separate room (ward) for changing clothes
- Toilet and shower facilities in an adjacent room, or directly in the ward
- Possibility of sedation, intravenous anesthesia
- Using carbon dioxide instead of air for insufflation (straightening the intestinal lumen from the inside)
- Anal anesthesia

Indications for colonoscopy
The main indications for colonoscopy are abdominal pain and periodic bleeding from the rectum. It is also necessary for clinical observation of patients with previously detected colon tumors or chronic colitis. Emergency colonoscopy is performed for intestinal obstruction, bleeding and a foreign body in the colon. Colonoscopy is considered the “gold standard” in diagnosing colon tumors. With modern equipment, it is quite well tolerated by patients. According to materials from American authors, colonoscopy, performed in the presence of the above indications, makes it possible to reduce the incidence of deaths from rectal cancer by 75%.
