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.
内镜下切除术（内镜黏膜切除术[EMR]和内镜黏膜下剥离术[ESD]）已成为特定早期胃癌（EGC）的一线治疗方式。在韩国，由于国家癌症筛查计划以及设备和技术的发展，EGC的内镜下切除数量急剧增加。关于EGC患者内镜下切除术后的短期和长期结果有许多报道。在绝对标准和选定的扩展标准方面，复发和死亡方面的长期结果都非常好。此外，内镜下切除术可能被定位为取代手术胃切除术的主要治疗方式。为了获得这些结果，患者的选择、完整的整块切除程序、对切除标本的全面病理检查、对内镜下切除全过程的准确解读以及合理的随访策略是必要的。
