The examination is performed using a rectoscope – a rigid speculum 20 cm long and 1.5 cm wide, which is inserted through the passage into the rectum, observing the intestinal mucosa.

Preparation for the study is relatively simple. You should buy 2 rectal infusions (enema, rectanal or similar – available without prescription) from a pharmacy. The first infusion should be made 4 hours before the test and the second one about 2 hours before the test. On the day of the examination, you can eat and drink normally. You should take all your medication unless the doctor recommends otherwise.
