Our experience refers to 188 patients submitted to endoscopic polypectomy, of whom 61 (32.4%) also to subsequent endoscopic controls. The polyps removed during follow-up compared to those previously removed showed the following characteristic: 1) Higher frequency in right colon (p > 0.01); 2) smaller size (p > 0.1); 3) lower frequency of adenomas, not statistically significant; 4) high frequency of relapse in juvenile polyps.
