Korean Guidelines for Postpolypectomy Colonoscopic Surveillance: 2022 Revision

The risk of developing metachronous advanced neoplasia is associated with the presence of polyps in index colonoscopy. Therefore, it is essential to establish the optimal colonoscopy surveillance period following polypectomy. In the 2020s, international guidelines published by the US Multi-Society Task Force, European Society of Gastrointestinal Endoscopy, and British Society of Gastroenterology were revised. In 2022, the Korean postpolypectomy colonoscopic surveillance guidelines were revised to recommend surveillance for adenoma size ≥ 10 mm, ≥ 3 adenomas, tubulovillous or villous adenoma, adenoma with high-grade dysplasia, traditional serrated adenoma, sessile serrated lesion (SSL) with dysplasia, serrated polyp with size ≥ 10 mm, and ≥ 3 SSLs.
