The results of this study demonstrated that age and lesion location were related to the ESD procedure outcome.

The results suggest that patients with high-grade dysplasia on forceps biopsies should be considered candidates for endoscopic resection. Characteristics of gastric adenomas such as a depressed type, red color, and ulceration that may have foci of carcinomas in other parts of the adenomas also should be considered for endoscopic resection.

For the potential risk of progressive dysplasia, gastric IENs should be treated actively using the recently advanced therapeutic endoscopic techniques, regardless of the degrees of dysplasia.
