A novel entire traction method with clip-anchored nylon ring facilitating endoscopic submucosal dissection of early gastric cancer

A 48-year-old woman with a high-grade intraepithelial neoplasia of the gastric antrum was referred for ESD treatment.The difficulty of ESD is to expose the submucosa,especially in difficult sites and lesions with severe fibrosis.Adequate submucosal exposure is the most critical technology to reduce complications and improving efficiency.Here we report a novel entire traction method to facilitate safe and efficient ESD.
