Post-Polypectomy Followup Recommendations Without Pathology, Is it Possible? Preliminary Results

Aims Appropriate post-polypectomy surveillance recommendations are an important performance measure for colonoscopy. We aimed to determine the rate of recommendations change due to the pathology results of villous component or high-grade dysplasia in 1-4 polyps smaller than 10 mm.

Methods Retrospective study included all consecutive colonoscopies in a single center in 2019. Colonoscopies with any type of polyp were analyzed for size, number and histopathology finding. Polyps with size less than 10mm and histopathology results showed villous component or high-grade dysplasia was considered as polyps needed change of follow up recommendations.

Results We included 1,145 patients, 1135 colonoscopies were included in the polyp’s analysis, 158 colonoscopies were excluded due to poor preparation. Mean age 59±14.1, 567 (49.5 %) males. Polyps and adenoma were detected in 448 (39.5 %) and 363 (32 %) colonoscopies. 1-2 polyps were found in 317 (27.9 %) colonoscopies and 3-4 polyps in 69 (6 %) colonoscopies. In 114 (25.4 %) colonoscopies the size of the polyp was ≥10mm. based on the pathology results, in 49 (10.9 %) colonoscopies the polyp was non-adenoma and in 36 (8 %) the polyp was hyperplastic. In 302 (67 %) colonoscopies the pathology results showed tubular adenoma with low grade dysplasia. In 11 (2.5 %) and 11 (1.4 %) cases with small polyps’ villous component and high-grade dysplasia was found in the pathology results.

Conclusions Pathology results change the recommendation for post polypectomy only in very small proportion of colonic polyps ≤10mm, only 1.4 % with high grade dysplasia and 2.5 % villous component .
