Sa1687 Newly-Developed ESD (CSL-ESD) for Early Gastric Cancer Using Convenient and Low-Cost Lifting Method (Lifting Method Using Clips and Snares) for Lesions is Clinically Useful

Since endoscopic submucosal dissection (ESD) was developed to treat early cancers of the GI tract, it has been becoming widely used as a minimally invasive treatment. However, there are still some cases difficult even for well-trained endoscopists depending on surgical site or presence/absence of scarring (fibrosis). But, if we can provide fields of operation/surgical wounds that are easy to operate by inserting an endoscope and dissection devices after lifting the area to be dissected so as to dissect the submucosa easily like the left hand of a surgeon does, the procedure seems to become more efficient and safer. We thus developed a safe and reliable, as well as, low-cost and convenient technique that makes it easier to perform dissection procedure by lifting the lesion using clips and snares (Clip- and Snare-Lifted Endoscopic Submucosal Dissection: CSL-ESD).
