A retrospective review of all colonoscopic polypectomies performed in a busy surgical endoscopy unit over a 6-month period was undertaken. All patients were included who presented with colonic polyps measuring less than 1 cm in diameter for which sufficient specimens were available for histopathologic examination. In all, 262 were polyps removed from 206 patients; of these, 158 (60%) were neoplastic. There was a statistically significant predilection for polyps in the right colon to be neoplastic. Worrisome histologic patterns (severe dysplasia, carcinoma in situ, or invasive carcinoma) were seen in 18 specimens (6.5%). In two patients, polypoid carcinoma could be identified; in one case it involved a lesion measuring 0.2 cm in diameter. Since these lesions exhibit no distinctive gross features, only their endoscopic removal and histologic study can ensure proper diagnosis and treatment.
