Endoscopic resection (Endoscopic mucosal resection [EMR] and endoscopic submucosal dissection [ESD]) is already established as a first-line treatment modality for selected early gastric cancer (EGC). In Korea, the number of endoscopic resection of EGC was explosively increased because of a National Cancer Screening Program and development of devices and techniques. There were many reports on the short-term and long-term outcomes after endoscopic resection in patients with EGC. Long-term outcome in terms of recurrence and death is excellent in both absolute and selected expanded criteria. Furthermore, endoscopic resection might be positioned as primary treatment modality replacing surgical gastrectomy. To obtain these results, selection of patients, perfect en bloc procedure, thorough pathological examination of resected specimen, accurate interpretation of whole process of endoscopic resection, and rational strategy for follow-up is necessary.
