Abstract

OBJECTIVE: The finding of colonic inflammation concurrently with a juvenile retention polyp (JRP) may have prognostic value. However, the significance of abnormal mucosal histology with JRP has not been evaluated. We evaluated the significance of mucosal histology at the time of JRP removal with respect to future development of inflammatory bowel disease (IBD) and polyp recurrence. METHODS: The medical records of patients who had an endoscopic polypectomy performed at the Children's Hospital of Philadelphia (CHOP) from 1/1/87 through 4/30/98 were retrospectively reviewed. RESULTS: JRP was histologically identified in 96 patients. A total of 54 patients had colonic mucosal biopsies: 30 (55.6%) had normal histology and 24 (44.4%) had colitis. Of the 24 patients with colitis, 14 patients (58.3%) had inflammation at the polyp site. Twelve of these patients had additional inflammation elsewhere in the colon. Nine (37.5%) had inflammation elsewhere in the colon; however, biopsies around the polyp site were not obtained. One patient with inflammation did not have the location of the polyp documented. Four patients (16.7%) had IBD at the time of polypectomy; two were diagnosed prior and two coincident with JRP. None have subsequently been diagnosed with IBD. There was no difference in polyp recurrence between those with or without inflammation (16.7% [4/24] vs 10.0% [3/30]). The mean follow-up period was 72.4 months (range, 5-142 months). CONCLUSIONS: In our experience, histological mucosal inflammation is a common finding with JRP. This inflammation may be a precursor for the development of JRP but has no predictive value for polyp recurrence. This colitis does not seem to be associated with IBD. (C) 2000 by Am.
