COLORECTAL SCREENING. FIRST RESULTS

Abstract

Objective: retrospective evaluation of the results of the 2nd stage of implemented colorectal screening program by colonoscopy.Materials and methods. In 2015–2017, The Department of Health of the Tyumen region is implementing a colorectal screening program. First stage of the program: the test for occult blood, 2nd stage: screening colonoscopy.Results. Achieved 2157 screening colonoscopies for patients aged 55–65 years with a positive fecal immunochemical test for fecal occult blood. In 531 (24.6 %) patients adenoma and adenocarcinoma of the rectum and colon were revealed (adenomas verified in 365 (23.1 %) cases, adenocarcinoma – in 33 (1.5 %) cases). Of the total number of verified neoplasia (618 cases of localization), 365 (59 %) cases of adenoma and adenocarcinoma were located in the rectum and sigmoid colon, 253 (41 %) cases – in the descending colon, transverse colon, ascending colon and cecum.Conclusions. In the completed study, the fecal immunochemical test and, with a positive result, a video-colonoscopy were performed at the 1st stage of colorectal screening for patients aged 50–65 years. In 98 % of cases, intubation of the cecum and the time of colonoscope removal for at least 6 minutes allowed to obtain a value of adenoma detection rate ~25 %, which is indicator of the effectiveness of the performed colorectal screening.
