Gastric cancer is the most common cancer worldwide. The proportion of early gastric cancer (EGC) cases at diagnosis has increased because of the use of mass screening endoscopy in older adults. Endoscopic mucosal resection has become the standard treatment for EGC in cases with standard indications because of its low risk of lymph node metastasis. A new endoscopic method, endoscopic submucosal dissection, has recently become available. This method allows en bloc resection without limitation of the size of the lesion. The goal of this article is to review the history and methods of endoscopic treatment with EGC, the conventional and extended indications, the therapeutic outcomes, and the complication rates.
