This study aims to evaluate the role of colonoscopy in patients presenting with hematochezia who are \u226450 years old. &lt;b&gt;&lt;i&gt;Methods:&lt;\/i&gt;&lt;\/b&gt; A retrospective review of all patients aged \u226450 years who underwent colonoscopy for hematochezia in 2012 was conducted. Patient demographics, endoscopic details, and histological results were analyzed. Patients were stratified by age to compare differences in outcome. &lt;b&gt;&lt;i&gt;Results:&lt;\/i&gt;&lt;\/b&gt; A total of 361 patients with a median age of 44 (range, 18-50) years were reviewed. Hemorrhoid (&lt;i&gt;n&lt;\/i&gt; = 183, 69.6%) was the most common etiology. Seventy-two neoplastic polyps were identified in 48 (13.3%) patients. There was a significantly larger proportion of patients aged 41-50 years who had neoplastic polyps compared to those aged \u226440 (18.8 vs. 3.8%, &lt;i&gt;p&lt;\/i&gt; \u2264 0.001); 43.8% (&lt;i&gt;n&lt;\/i&gt; = 28) of the neoplastic polyps found in those aged 41-50 were proximal to the splenic flexure. The only 2 (0.5%) patients with malignancy were aged 41-50 years. &lt;b&gt;&lt;i&gt;Conclusion:&lt;\/i&gt;&lt;\/b&gt; Performing colonoscopy in patients presenting with hematochezia should be strongly considered for those aged 41-50 years in view of the significant likelihood of underlying neoplastic polyps compared to those aged \u226440 years.<\/jats:p>","DOI":"10.1159\/000481686","type":"journal-article","created":{"date-parts":[[2017,11,2]],"date-time":"2017-11-02T22:03:34Z","timestamp":1509660214000},"page":"90-95","source":"Crossref","is-referenced-by-count":8,"title":["Is Colonoscopy Indicated in Young Patients with Hematochezia"],"prefix":"10.1159","volume":"4","author":[{"given":"Frederick H.","family":"Koh","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aaron","family":"Seah","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dedrick","family":"Chan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jingyu","family":"Ng","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ker-Kan","family":"Tan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2017,11,3]]},"container-title":["Gastrointestinal Tumors"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/481686","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/481686","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T17:04:01Z","timestamp":1745427841000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000481686"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017]]},"references-count":0,"journal-issue":{"issue":"3-4","published-online":{"date-parts":[[2018,2,23]]},"published-print":{"date-parts":[[2018,3,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000481686","archive":["Portico"],"relation":{},"ISSN":["2296-3774","2296-3766"],"issn-type":[{"type":"print","value":"2296-3774"},{"type":"electronic","value":"2296-3766"}],"subject":[],"published":{"date-parts":[[2017]]}}}
