Colonoscopy process

Colonoscopy procedure - instrumented colonoscopy, or colonoscopy and virtual colonoscopy (CT colonoscopy), requires a clean colon.

This means that before the test, the entire intestinal wall must be thoroughly evacuated so that any abnormalities can be seen.

In the instrumental test, a fibre-optic device with a thickness of a pinky is inserted into the rectumthrough.

The test is uncomfortable, but it is now routine practice in some places to use painkillers and mild sedatives during the test so that the patient feels nothing.

For imaging methods, it is also important to coloncleaning. Next, an air-mixed contrast agent is injected through the rectum and the colon is 'photographed'. A histological sample can only be obtained by instrumental examination.
