The indications for performing colonoscopy in Iranian children – a cross-sectional study

Background: Colonoscopy is the gold standard dia­gnostic method for colon diseases providing an excellent view of the mucosal surface of the colon and terminal ileum. Colonoscopy in children is indicated for dia­gnosis and treatment of gastrointestinal diseases. In this study, we evaluated the reasons for performing colonoscopy in children. Methods: This was a descriptive cross-sectional study including all children referred for colonoscopy to the Gastroenterology clinic affiliated with the Shiraz University of Medical Sciences. The children were selected by a convenient sampling method. Statistical analysis was conducted in the SPSS 22 software. Results: From 389 children referred for colonoscopy, 203 were boys and 186 were girls. The mean age was 8.36 ±4.8 years. The most common reason for colonoscopy was rectal bleeding (63.5%) with the most prevalent dia­gnoses being juvenile polyp and inflammatory bowel disease, each accounting for 11.3% patients. Conclusions: The most common findings of colonoscopy were polyp, IBD and colon inflammation, and the most prevalent symptoms leading to colonoscopy were rectal bleeding, chronic diarrhea, IBD treatment follow-up, suspected IBD and abdominal pain. The high prevalence of pediatric patients presenting with these symptoms indicates the increasing importance of colonoscopy in these patients.
