Abstract:Background:Endoscopic submucosal dissection(ESD)has the advantages of high complete resection rate, less trauma and higher safety than open surgery. However, ESD has high technical requirements and is difficult to operate, especially when submucosal dissection fails to fully expose the submucosa. To create a good operational field of vision and achieve accurate cutting, a variety of endoscopic assisted traction methods have emerged. Our study team has invented a new traction method, that is, snare combined wit… Show more
