Objective. To improve the efficiency of detecting early forms of colorectal cancer (CRC) and precancerous diseases (polyps) by developing and adhering to quality standards for performing colonoscopy screening of CRC.

Materials and methods. Men and women aged 45 to 70 and having no concomitant pathology were the screening objects. The total colonoscopy is performed in the endoscopy room with the necessary anesthetic equipment for the examined person sedation and should be performed in more than 90% of cases. The rate of the cecum intubation is considered acceptable in >95% of cases. The time for the device removing from the colon should be at least 6 minutes in 90% of cases. Complications in the form of the bowel perforation account to <1/1000 or of bleeding — 1/200. The colon should be prepared adequately in ³90% of cases. Polyps ³0.6 cm large should be removed in > 95% of cases and sent for routine histological examinations in 100% of cases.

Results. Within the frames of the pilot project, an algorithm and implementation of CRC screening has been developed since 2014 in the Republic of Belarus. All the participants of the screening program have been removed the identified polyps (100%). The histological structure of all the removed polyps was studied. The five-year experience of the screening colonoscopy showed no recurrence after polypectomies. There was no complication revealed during the preparation of the patient for the study, during the colonoscopy and in the immediately after manipulation period during the screening procedures. During the screening, all the established quality standards for colonoscopy were observed and achieved indicating at the possibility of following all recommendations for the CRC screening.
