Adenomas with severe dysplasia and early carcinoma of the colon-rectum: our experience of 27 patients.

Authors report their experience in the treatment of adenomas with severe dysplasia and early cancer of the colon-rectum confirming that the endoscopic resection of these lesions is safe and curative when completely removed and no submucosal invasion is found. Between 1995 and 1999, 219 patients underwent colonoscopy and 287 polyps were removed. Histologic examination showed 217 adenomatous polyps (75.6%), 58 non adenomatous (20.2%) and 12 early carcinomas (4.2%). Severe dysplasia was found in 15 adenomas. There were no complications. The Authors focused on 12 patient with early carcinoma and 15 with severe dysplasia. The mean follow-up was 34 months. No recurrences were observed, supporting that this procedure is the treatment of choice in selected cases.
