Aim: To determine the frequency of various etiological factors causing lower gastrointestinal bleeding by endoscopy. Study Design: A cross-sectional study. Place and Duration: In the department of Gastroenterology and Pediatrics, PIMS Hospital, Islamabad for one year duration from March 2019 to March 2020. Methodology: 160 patients with rectal bleeding undergoing colonoscopy were enrolled in the study. Results: The study included 160 patients. The male to female ratio was 2.9: 1. The average age was 7.05. All patients had rectal bleeding. Rectal polyps 74 (46.3%), chronic colitis 20 (12.5%), infectious colitis 19 (11.9%), nonspecific colitis 19 (11.9%) are the most common diagnoses on endoscopy and normal endoscopy results were noted in 27 (16.9%). Conclusion: We conclude that rectal polyps are the most common cause of children with rectal bleeding. Colonoscopy is effective for correct diagnosis and further treatment of rectal bleeding. Key words: rectal bleeding in children, colonoscopy in children.
