BACKGROUND/AIMS: Accurate in vivo differentiation of @entity1586 histology may serve to prevent the resection of diminutive @entity1127 in the distal colon or the need for histologic assesment of diminutive @entity1127 after resection. The clinical implementation of these strategies depends on the prevalence of advanced histologic findings among diminutive @entity1127 . We aimed to determine the prevalence of advanced histologic features (villous features, high-grade @entity1141 , and @entity420 ) in diminutive @entity1586 and compare it to small and larger @entity1127 . @entity1 /METHODS: The data of @entity1 who had undergone elective colonoscopy at a tertiary-care referral center were retrospectively reviewed. The size, morphology, and location of all @entity1127 were recorded. @entity1127 were divided into 3 groups according to their size: diminutive ( <= 5 mm), small (6-9 mm), and large (>=  10 mm). RESULTS: A total of 7160 @entity1127 in 3226 eligible @entity1 were evaluated. The mean diameter of the @entity1127 were 6.7    4.9 mm. Histopathologic diagnosis were adenomatous in 4548 (63.5%) and non-adenomatous in 2612 (36.5%). Out of 7160 @entity1127 , 4902 (68.5%) were diminutive (1-5 mm), 1360 (19%) were small (6-9 mm), and 898 (12.5%) large (>=  10 mm) @entity1127 . Among the diminutive @entity1127 2739 (55.9%) had adenomatous histology. There were 66 @entity1127 (1.3%) with advanced histology in the diminutive group, 72 (5.2%) in the small group, 263 (29.2%) in the large polyp group. Diminutive @entity1127 had a lower frequency of advanced histology compared to small and large @entity1127 (p = 0.001). When the histology of the @entity1127 were evaluated based on the size of the largest polyp the @entity1 has, 2202 @entity1 had polyp(s)  <= 5 mm. The frequency of advanced histology was 2.2% in these @entity1 . CONCLUSIONS: The prevalence of advanced histology in diminutive @entity1127 is quite low (1.3%) which supports the clinical implementation of discard, resect and discard strategies in diminutive @entity1127 .
