Core Tip
Core Tip: The location of gastric neoplasms in endoscopic submucosal dissection (ESD) may affect the level of technical difficulty and the efficacy and safety profile. There is limited scientific evidence assessing the clinical impact of gastric tumor location on ESD outcomes. In tumors in the proximal stomach, it is essential to carefully and individually select those cases that would benefit from gastric ESD eradication.
