Prevalence of superficial colorectal neoplasia according to videoleocolonoscopy in narrow light spectrum (NBI) with high magnification

Video ileocolonoscopy in NBI and high magnification modes is effective in detecting superficial colorectal neoplasia (SCN). PKN were found in 76% of patients (95% CI 70-82%), the detection index was 2.84. There is no dependence on the sex of patients in the number of cases of PKN (p = 0.9; c2 = 0.02). The number of detected PKN in one patient in the group of men is greater than in one patient in the group of women (p <0,00001; c2 = 22,9). PKN are often localized in the left half of the colon 76% (p <0,00001; c2 = 282,8). Further studies on the age distribution of PKN, comparison of endoscopic and morphological type of PKN are needed.
