[Endoscopic resection of early gastric cancer].

As the proportion of early gastric cancer has been increasing with national cancer screening program, endoscopic treatment for early gastric cancer has been expanded with the progress of endoscopic technique and accessories. Recently, expanded indication of endoscopic resection for early gastric cancer has been proposed with technical and instrumental advances. Although endoscopic complete resection rate has been improved, critical evaluation should be made for appropriate indication of endoscopic resection in terms of risk of occult metastasis. Recent advances of normal orifice transluminal endoscopic surgery (NOTES) might be a future solution including regional lymph node dissection.
