Background/Aims: Sigmoidoscopy is performed in most medical centers to evaluate the distal colons of young adults presentingwith hematochezia who are at risk of developing proximal lesions. Colonoscopies offer more complete evaluations but are associatedwith a higher incidence of complications and possible low yield. Methods: An analysis was conducted on colonoscopies performed in our center on patients 40 years of age or younger. The studypopulation was sub-divided into 2 age groups for analysis: <30 years of age and 30–39 years of age. Results: We recruited 453 patients for the study. Patients were 115 and 338 individuals that were <30 and 30–39 years of age,respectively. Hemorrhoids was identified as the cause of bleeding in the majority of cases. The overall incidence of polyps was 6.5%;this was significantly higher in the 30–39 age group (7.4% vs. 1.7%, p=0.026). There were two cases of advanced/malignant polyps. While the majority of the polyps were in the distal colon, 28% of the polyps in the older age group were found in the proximal colon. There was one case of colonic perforation. Conclusions: Colonic polyps are more prevalent in patients aged 30–39. Colonoscopies should be considered for patients over theage of 30 with rectal bleeding.
