| [ Summary ] | In endoscopic mucosal resection (EMR), the lesion is captured with a snare and resected by applying high-frequency current after submucosal injection of physiological saline. In piecemeal EMR, a large nodule is first cut into a large piece to accurately perform histological diagnosis (planned piecemeal EMR). In endoscopic submucosal dissection (ESD), the circumference of the lesion is incised using a needle-type knife, and the submucosal layer is then dissected after submucosal injection of sodium hyaluronate solution. A technique in which snaring is performed without dissecting the submucosal layer after incising the circumference of the lesion is defined as "precutting EMR" and a technique in which the submucosal layer is dissected and snaring is performed after the ESD procedure is defined as "hybrid ESD" in these guidelines. |
