Optimal Follow-up Program after Colonoscopic Removal of Colorectal Neoplasia

We have evaluated the optimal follow-up program after colonoscopic removal of colorectal neoplasia (adenoma and cancer), analyzing 354 cases who had undergone a colonic polypectomy and mucosectomy. To avoid overlooking lesions, we should perform at least two consecutive follow-up TCS (total colonoscopy) after the endoscopic resection of lesions. Based on our results, we advocate a follow-up program as follows. For the cases who have less than 3 le-sions with only adenoma at two follow-up TCS, we should perform one follow-up TCS every five years. On the other hand, for the cases who have less than 3 lesions with cancer, more than 4 lesions with adenoma or cancer at two follow-up TCS, we should perform follow-up TCS once every three years.
