| [ Summary ] |
The aim of follow up after colorectal ESD/EMR is early detection of local residual/recurrence, metastasis, and metachronous lesions. The Japan Gastroenterological Endoscopy Society (JGES) guidelines state that "In adenoma or pTis carcinoma, when piecemeal resection is used, or the tumor margin after resection is unclear, and the curability cannot be accurately evaluated, colonoscopy should be done approximately 6 months after the endoscopic treatment" and "Colonoscopy should be carried out within 3 years after endoscopic treatment." |
