In our analysis of a screening cohort of 10737 subjects undergoing screening colonoscopy, a total of 15877 neoplastic lesions were detected, of which 10816 (68.1%) were diminutive lesions. Of those diminutive lesions, 90 (0.83%) had a villous component, 14 (0.1%) had high-grade dysplasia, and none had invasive cancer. Only 1.3% of patients were advised to decrease their surveillance interval because of unfavorable histology. Laws regulating medical practice, uncertainty regarding the accuracy of endoscopic diagnosis of diminutive polyps outside of academic centers, and the relatively low cost of pathological analysis are among the barriers to adopting a 'resect and discard' practice in Taiwan.enadvanced neoplasm; colon polyp; colonoscopy; colorectal cancer; image-enhanced endoscopy[SDGs]SDG3adenoma; adult; age distribution; aged; cancer staging; Colonic Polyps; colonoscopy; Colorectal Neoplasms; early diagnosis; female; human; immunohistochemistry; male; middle aged; needle biopsy; pathology; prevalence; procedures; retrospective study; sex ratio; Taiwan; tumor invasion; Adenoma; Adult; Age Distribution; Aged; Biopsy, Needle; Colonic Polyps; Colonoscopy; Colorectal Neoplasms; Early Detection of Cancer; Female; Humans; Immunohistochemistry; Male; Middle Aged; Neoplasm Invasiveness; Neoplasm Staging; Prevalence; Retrospective Studies; Sex Distribution; Taiwanjournal article10.1111/den.12260247501512-s2.0-84925284915WOS:000334685300012https://scholars.lib.ntu.edu.tw/handle/123456789/544678
