Advanced Endoscopic Imaging in Colonoscopy

The aim of the study is to evaluate the usefulness of high-tech endoscopy in clinical practice.
The important elements of this evaluation are:
* Evaluation of the character of neoplastic lesions in the colon based on different imaging techniques
* Verification of the endoscopic image with histopathologic descriptions
* Establishing the type of the lesion on the basis of Kudo and NICE classifications
* Comparison of the result of histopathological examination with the macroscopic type of the lesion
* Determination of the most advanced lesions (MAL)
* Comparison of the cecal intubation time
* Evaluation of the type of anesthesia used during colonoscopy
* Subjective assessment of the severity of pain according to VAS (visual analogue scale)
* Comparison of the accuracy of the location of lesions on the basis of endoscopic navigation
* Comparison of the total examination time
* Comparison of adenoma detection rate
