We evaluated the diagnostic yield, procedural success, and safety of screening colonoscopy in patients aged \u226575 years.Methods: We retrospectively reviewed 602 patients aged \u226575 years who underwent screening colonoscopy between January 2013 and December 2024. Patients were stratified into two age groups: 75\u201379 years (n=486) and \u226580 years (n=116). Baseline characteristics, procedural outcomes, and safety were compared.Results: Baseline characteristics were comparable between groups. The detection rates were 10.5%, 6.8%, and 0.9% for non-advanced adenoma, advanced adenoma, and colorectal cancer, respectively. Cecal intubation success was high in both groups (98.1% vs. 99.1%, p=0.454), and adequate bowel preparation rates were similar (71.2% vs. 72.4%, p=0.880). Sedation was used less frequently in patients aged \u226580 years (65.5% vs. 76.7%, p=0.013). Complications were rare (1.5%) and comparable between groups, with only mild events.Conclusions: Screening colonoscopy in adults aged \u226575 years demonstrated high procedural success, substantial neoplasia detection rates, and low adverse event rates, with comparable outcomes in patients aged \u226580 years. However, overall clinical benefit should be interpreted cautiously, particularly in those aged \u226580 years, supporting an individualized approach.<\/jats:p>","DOI":"10.5946\/ce.2026.020","type":"journal-article","created":{"date-parts":[[2026,9,18]],"date-time":"2026-09-18T04:18:43Z","timestamp":1789705123000},"page":"843-850","update-policy":"https:\/\/doi.org\/10.5946\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Effectiveness
