Colonoscopy

The aim of a colonoscopy is to look at the entire length of the rectum and colon, the mucosa, and to look for sources of bleeding or narrowed bowel.
During the examination, it is also possible to take histological samples and remove whole polyps.

During a colonoscopy, the doctor will take a colonoscopy of the colon.
The doctor usually uses a flexible instrument about 160 centimetres long to look through the entire colon.
The device, called a colonoscope, uses fibre-optics to transmit light and images.
The image is displayed on a screen.
Free space is needed to move the device and to get the right image, so the doctor blows air into the colon through one of the colonoscope’s channels during the examination.
If necessary, he can also aspirate it or the diluted intestinal contents remaining in the bowel.
Special forceps can be used to take a tiny sample of tissue from a suspected lesion through the other small, thin channel of the device.
And with a loop heated by an electric current, entire polyps can be cut off at the base with relatively little risk of rebleeding.
The tissue sample obtained during colonoscopy can be examined under a microscope after proper processing.

Colonoscopy is usually performed in the left lateral position, but it may be necessary to turn the patient onto their back during the procedure.
In this case, the patient is carefully helped to lie on his/her back by the assistant and the doctor.
The device is introduced into the colon through the anus and is passed slowly and carefully, usually to the junction of the large and small bowel (cecum, abdominal valve).
A meticulous inspection of the bowel is usually carried out while the instrument is slowly pulled out.
In the video below, Dr. Eva Csatár, Chief Medical Officer at ProctoMed Center, explains the colonoscopy procedure:

If you are taking a blood thinner, check with your cardiologist to see if you can stop taking it in the 4 days before the test, as you should stop taking it before the test.

A fresh laboratory test before the procedure is only necessary if the patient has other medical conditions or if they want to have the test under anaesthesia.
It is very important to prepare properly, as only a properly cleansed intestinal tract can allow a full examination.
Only easily digestible, fibre-free foods such as soups, mashed potatoes, pasta and dairy products should be eaten 3 days before the test.

– Stop taking any medicine containing aspirin or clopidogrel one week before the test.
– If taking Syncumar, Marfarin, discuss the need to switch to injectable treatment (LMWH) with your doctor.
– Xarelto, Eliquis, Praxada and similar medicines should be discontinued the day before the study.
– Do not administer LMWH (injection) the night before the study or the morning of the day of the study.

– A fibre-free diet (no vegetables or fruit).
– DO NOT eat small-grain foods, muesli or drinks that can stain the intestinal lining.
– What you can eat: white bread, pasta, low-fat meat, dairy products, eggs, mashed potatoes, apple puree.
– Drink at least 2 litres of fibre-free liquids (weak tea, filtered soup, water, light coloured soft drinks).

– A light breakfast (kefir, yoghurt, 1 slice of bread, coffee is the last thing you drink).
– At noon, only the broth is allowed.
– Do not eat solid food.
– Dissolve in a cup of water and drink the first dose of PICOPREP at 2pm, then drink 2 litres of liquid by 6pm.
– At 6pm, dissolve in a cup of water and drink the second dose of Picoprep and drink 2 litres of liquid again by 10pm.

If you feel hungry, you can have glucose or drink NUTRIDINK formula, or maybe some baby biscuits.
You should take your regular medicines with a 2 hour interval between the laxative and the medicine.
After the test, you will need an escort to pick you up, as the anaesthetic injection or anaesthetic will require an escort to leave the hospital and you will not be allowed to drive.
Do not drink any liquids for 6 hours before the test.

At 18:00 the day before the test, you take the first sachet of powder with the amount of fluid described.
And at 6:00 a.m. on the day of the test, you take the 2nd tablet.
sachet of powder with the described amount of fluid.
You may also eat a light breakfast (toast, cheese) at 6am on the day of the test.
