Colonoscopy in Hong Kong Chinese children

Abstract

AIM: To investigate the safety and diagnostic yield of colonoscopy in Chinese children in whom the procedure is not often done. METHODS: We conducted a retrospective review of all colonoscopies in consecutive children who underwent their first diagnostic colonoscopy from Jan 2003 to 2008. RESULTS: Seventy-nine children (48 boys, 31 girls; mean age 9.2 ± 4.2 years) were identified and reviewed with a total of 82 colonoscopies performed. Successful caecal and ileal intubation rates were 97.6% and 75.6% respectively. Forty patients (50.6%) had a positive diagnosis made in colonoscopy and that included colonic polyps (23), Crohn's disease (12), ulcerative colitis (1), and miscellaneous causes (4). 80% of polyps were in the rectosigmoid colon. All but one were juvenile hamartomatous polyps. The exception was an adenomatous polyp. The mean ages for children with inflammatory bowel disease (IBD) and polyps were 11.3 and 4.3 years respectively. There was no procedure-related complication. CONCLUSION: Colonoscopy is a safe procedure in our Chinese children. The increasing diagnosis of IBD in recent decades may reflect a rising incidence of the disease in our children. © 2010 Baishideng. All rights reserved.
