| [ Summary ] | Appropriate surveillance is essential for the purpose of detection of local recurrence and metachronous cancer after endoscopic resection of early colorectal cancers. If baseline colonoscopy was insufficient due to incomplete insertion, poor colon cleansing or inadequate withdrawal, an early repeat colonoscopy should be planned. Surveillance programs should start after a high quality colonoscopy. As surveillance colonoscopy at 1 year after endoscopic resection of Tis cancer is desirable because baseline Tis cancer is higher risk than advanced adenoma. Additional radiological examinations and serum tumor markers to detect distant metastases are required for surveillance after T1 cancer. Shorter surveillance colonoscopy around the 6 month mark is desirable after piecemeal endoscopic resection because recurrence frequent occurs at about 20 %. | |
