Objectives
Narrative objectives1 After endoscopic submucosal dissection (ESD) for gastric cancer, to clarify the appropriate endoscopic test interval in order to discover the metachronous gastric cancer in endoscopic therapy adaptive.
Basic objectives2 Others
Basic objectives -Others After early gastric cancer ESD, metachronous gastric cancer at a constant rate is for generating, regular endoscopy is performed. Usually, as surveillance of stomach cancer that occurs in metachronous, is often carried out every 12 months, it has been found beyond the endoscopic healing adaptation with 0-15% of metachronous gastric cancer. So we, the interval at which to implement the upper gastrointestinal endoscopy after ESD test for gastric cancer is assigned to 6 months and 12 months do the prospective study, found in the off-label of endoscopic therapy by reducing the inspection interval It is possible to reduce the frequency of occurrence of metachronous gastric cancer to examine whether it is possible that.
