| [ Summary ] | Endoscopic submucosal dissection (ESD) has recently been applied to treatment of colorectal lesions, enabling en bloc resection of any size lesion, accurate histological diagnosis, and a reduced possibility of local recurrence or residual lesions. Thus, the strategy for treatment of colorectal neoplasms, except for those involving invasive cancer, has changed to include expanded indications for endoscopic treatment. Considering the main purpose of colonoscopic surveillance after ESD, early detection and treatment for metachronous neoplastic lesions during the follow-up period should be conducted. The American Cancer Society guidelines recommend an interval for colonoscopy surveillance of 3 years for patients who have neoplastic lesions over 20 mm in size. This was mainly based on clinical data collected from Western countries. The quality of colonoscopy performed is different than that in Japan. It is hoped that the results of a prospective study conducted by Japan Polyp Study group may lead to appropriate surveillance programs after screening colonoscopies or to polypectomies based on clinical outcomes. | |
