Although conventional thermal techniques are effective, the thin duodenal wall and distinctive anatomy have driven interest in cold resection techniques that avoid electrocautery\u2010related injury. This narrative review individually appraises cold snare polypectomy (CSP), cold forceps polypectomy (CFP), and cold snare endoscopic mucosal resection (CS\u2010EMR) for duodenal SNADETs. Management of selected small low\u2010grade adenomas should be individualized, with careful surveillance considered as an alternative to immediate resection. When resection is chosen, CSP is the principal cold resection technique for lesions &lt;10\u00a0mm that are optically diagnosed as low\u2010grade adenomas using white\u2010light imaging and narrow\u2010band imaging. CSP appears technically feasible and safe for selected small SNADETs. However, its shallow resection depth limits vertical margin assessment. Available follow\u2010up data suggest low recurrence rates, and recurrent lesions are generally small and endoscopically manageable. This review also discusses the importance of pretreatment optical diagnosis, appropriate lesion selection, technical considerations, and structured surveillance after cold resection. CFP may be considered for carefully selected diminutive lesions, although the supporting evidence remains limited. Although CS\u2010EMR can enable resection of larger lesions, substantial recurrence rates and the reported risk of perforation argue against its routine use. Overall, CSP is the principal cold resection technique for selected small low\u2010grade adenomas, whereas CFP and CS\u2010EMR have more limited roles.<\/jats:p>","DOI":"10.1002\/deo2.70429","type":"journal-article","created":{"date-parts":[[2026,9,7]],"date-time":"2026-09-07T12:20:38Z","timestamp":1788783638000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Cold
