Background/Aims: Colorectal polyps are a common cause of lower gastrointestinal bleeding in children. Our aim was to study the causes of isolated lower gastrointestinal bleeding and to analyze the characteristics of the colorectal polyps found in our cohort. Methods: We retrospectively reviewed colonoscopic procedures performed between 2007 and 2015. Children with isolated lower gastrointestinal bleeding were included in the study. Results: A total of 185 colonoscopies were performed for isolated lower gastrointestinal bleeding. The median patient age was 8 years, and 77 patients (41.6%) were found to have colonic polyps. Normal colonoscopy findings were observed and acute colitis was detected in 77 (41.6%) and 14 (7.4%) patients, respectively. Single colonic polyps and 2–3 polyps were detected in 73 (94.8%) and 4 (5.2%) patients with polyps, respectively. Of the single polyps, 69 (94.5%) were juvenile polyps, among which 65 (94.2%) were located in the left colon. Conclusions: Single left-sided juvenile polyps were the most common cause of isolated lower gastrointestinal bleeding in our study. It was rare to find multiple polyps and polyps proximal to the splenic flexure in our cohort. A full colonoscopy is still recommended in all patients in order to properly diagnose the small but significant group of patients with pathologies found proximal to the splenic flexure.
