In contrast to conventional endoscopy or colonoscopy , the  colonoscope video is equipped with a chip that has a powerful camera at 1.25 million pixels.

In this way it allows to see the intestinal wall extensively and ensures the registration of photographs and videos in HD quality.

The diagnoses are made using filters in front of the white light source of conventional lighting.

The colonoscopy video also allows the proctologist to obtain biological material for analysis and eliminate small polyps.
