ESD procedure using MLTD. a Multi-loop traction device (MLTD). b Snag the MLTD at the base of the clip, mount the clip in the rotatable clip device, and deliver into the stomach through the forceps port. c Deliver a clip with MLTD attached from the end of the endoscope, and attach to the proximal side of the lesion mucosa. d Using another clip, snag an MLTD ring, and apply countertraction by attaching the clip to the gastric wall contralateral to the lesion. e Optimal traction and visualization are obtained during submucosal dissection. f The lesion is completely resected. ESD, endoscopic submucosal dissection; MLTD, multi-loop traction device
