Background
The available data regarding the prevalence, types, and clinical determinants of colonic polyps in children is limited.
Aims
We aimed to estimate the prevalence of colorectal polyps in a large cohort of children.
Methods
We conducted a cross-sectional study to determine the presence, number, and location of colorectal polyps reported in all children (0–20 years) who underwent colonoscopy at 14 pediatric facilities between January 2000 and December 2007 recorded in Pediatric Endoscopy Database System Clinical Outcomes Research Initiative (PEDS-CORI). We compared procedures with and without polyps with respect to procedure indication, age, sex, and race. We also reviewed a sample of histopathologic reports from one participating center.
Results
We analyzed 13,115 colonoscopy procedures performed in 11,637 patients. Colorectal polyps were reported in 810 procedures (6.1%; 95% CI: 5.7–6.5%) performed in 705 patients, and in 12% of patients with lower GI bleeding. Children with colorectal polyps were significantly younger (8.9 years vs. 11.9 years; p < 0.0001), male (58.3% vs. 49.0%; p < 0.001), non-white race (27.5% vs. 21.9%; p < 0.001), and had lower GI bleeding (54.4% vs. 26.6%; p < 0.001) as compared to children without polyps. In a sample of 122 patients with polyps from a single center, the histological types were solitary juvenile in 91 (70.5%), multiple juvenile in 20 (15.5%), adenoma in 14 (10.9%) and hyperplastic polyps in four patients (3.1%).
Conclusions
Colorectal polyps are detected in 6.1% overall and in 12.0% among those with lower gastrointestinal bleeding during pediatric colonoscopy. Approximately 26% are multiple juvenile or adenoma.
