A new technique for gastric endoscopic submucosal dissection: peroral traction-assisted endoscopic submucosal dissection

A new technique for pharyngeal endoscopic submucosal dissection: peroral countertraction (with video)

“…As we reported previously, 2,6 an adequate working space can be created by lifting the larynx with a laryngoscope; however, to make a well-visualized dissecting line, countertraction with some device is considered essential. Traction methods [7][8][9] have been reported in various segments of the GI tract, but not in the pharynx. According to these reports, when the target organs were the stomach or colon, innovative techniques were created by using clips in many cases because of the distance from the orifice to the lesion.…”

Endoscopic submucosal dissection with the pulley method for early-stage gastric cancer (with video)

“…Traction systems that facilitate ESD, such as the smallcaliber-tip transparent hood, 12 percutaneous tractionassisted ESD, 5 the magnetic anchor system, 6 external grasping forceps, 7 and the peroral traction method, 8 have been reported, although each has its own limitations. The small-caliber-tip transparent hood does not permit broad visualization of the cutting field; percutaneous tractionassisted ESD, which requires a laparoscopic port with a trocar, is a more invasive procedure; and the magnetic anchor system requires a large expensive control device, which is not yet available for clinical use, to generate a magnetic field.…”

Gastric endoscopic submucosal dissection assisted by a new traction method: the clip-band technique. A feasibility study in a porcine model (with video)

“…9 To facilitate the dissection, several methods have been proposed for use in the stomach and the colon: using longer-lasting solutions in the submucosa, 10 transparent hoods, 10 or traction methods. [12][13][14][15][16][17][18][19][20][21][22] The method proposed by Sakurazawa et al 21 has some similarities to ours. However, in their study, the second clip was applied not distally to the lesion, but on the opposite gastric wall.…”
