Since late 1960s, when gastric polyps were first removed with endoscopy using an electrocautery snare, the indications have been expanded parallel with improvements in endoscopic techniques as well as the development of new endoscopic devices. In this chapter, we outline the indications for endoscopic resection of early gastric cancer, describe three major endoscopic techniques, and the outcomes of endoscopic treatment including major complications are summarized, followed by our view of the future perspective of endoscopic minimally invasive treatment.
