[ Summary ] | This study investigated surveillance methods for post endoscopic treatment (polypectomy or endoscopic mucosal resection) for early colorectal cancer. Surveillance was defined as the following: (1) monitoring of the local residues/recurrence after endoscopic treatment, (2) monitoring of overlooked lesions, (3) discovery of new metachronous cancer. We recommended surveillance after endoscopic treatment in these cases. Cases of enblocked resected m cancer should be followed up on after one year, and then every two years. Cases of piecemeal resected m cancer should be followed up on after 3 to 6 months, and after that each subsequent year. In cases of sm cancer, follow-up endoscopy should be performed after 3 to 6 months and monitored for local residues or recurrence. After that, we should follow up after 6 months, and every year after that. New metachronous colorectal cancer was detected in about 86% within 7 years. It was concluded that a recommended surveillance program should be constructed according to individual cases, and it is thought that follow-ups should be re quired for at least seven years after endoscopic treatment. |
