Treatment outcomes of non-curative endoscopic submucosal dissection for superficial gastric neoplasia: A retrospective study at a tertiary care center in the United States.

Objectives: Endoscopic submucosal dissection (ESD) is a minimally invasive treatment for early gastric cancer; additional treatment may be recommended for patients in whom resection is not curative per the American Society for Gastrointestinal Endoscopy guidelines. The aim of this study was to assess treatment outcomes of ESD for gastric neoplasia, with a focus on cases of non-curative resection.

Methods: This was a retrospective study of all individuals undergoing ESD for the treatment of gastric adenocarcinoma or dysplasia in a high-volume tertiary care center in the United States.
