Kim NH, Jung YS, Lee MY, et al. - Researchers examined the risk of metachronous advanced colorectal neoplasia (ACRN) among patients with multiple diminutive or small adenomas. Based on baseline adenoma characteristics, they classified 9,733 patients (mean age: 45.8 ± 8.2 years) who underwent ≥ 1 adenoma removal and follow-up colonoscopic surveillance into following groups: group 1, 1–2 nonadvanced adenomas (NAAs)(n = 8,051); group 2, ≥ 3 diminutive NAAs (n = 293); group 3, ≥ 3 small NAAs (n = 258); and group 4, advanced adenomas (AAs) (n = 1,131). Outcomes revealed no differences in risk of metachronous ACRN among patients aged ≥ 50 years who underwent polypectomy of ≥ 3 diminutive NAAs, ≥ 3 small NAAs, and AA. This finding thus supports current guidelines recommending a uniform surveillance interval for these lesions.
