Juvenile polyp and colonoscopic polypectomy in childhood.

Objective: This study aimed to evaluate the clinical features of juvenile polyp and the usefulness of polypectomy with entire colonoscopy in children.

Methods: We retrospectively reviewed the medical records of 83 children who were diagnosed with having juvenile polyps.

Results: The mean age of the patients was 6.5±3.7 (range 1.3-14.5 years) years. The male to female ratio was 2.1: 1. Eighty one patients (97.6%) had hematochezia, of which the observed characteristics included red stool (74.1%), blood on wipe (13.6%). The time interval between the 1st episode of hematochezia and colonoscopy was 8.9±20.4 (ranged 0.1-48.0) months. The most proximal regions of colonoscopic approach were terminal ileum (96.4%). Sixty three patients (75.9%) had a solitary polyp and 20 patients (24.1%) had multiple polyps. The sites of the polyps were rectum (61.4%), sigmoid colon (23.5%). Eighteen polyps (15.1%) were found more proximal locations than rectosigmoid. The polyp size ranged from 0.3 to 5 cm. After the polypectomy, hematochezia recurred in 9 patients. Endoscopic hemostasis was performed in 2 patients due to severe bleeding. All procedures were carried out without using general anesthesia.

Conclusions: Juvenile polyp occurred in a wide range locations and had variable sizes and numbers, suggesting that colonoscopy on the entire colon is necessary. Colonoscopic polypectomy is a simple and useful therapeutic method in children with juvenile polyp.
