A new endoscopic fixation method using the commercially available Multi-Clamp: the "clamp technique".

In an unstable setting, even if the ESD knife is manipulated by removing one's right hand from the endoscope, the weight of the main body of the Multi-Clamp allows the endoscope to be fixed in place, allowing visibility to be maintained during the surgery. Before insertion of the endoscope, a Multi-Clamp was clamped with gauze into the base (near the opening of the forceps) of the soft part of the endoscope, which was then inserted.
