Endoscopic Resection of Gastric Submucosal Masses by a Dental Floss Traction Method

Figure 2

ESD with dental floss clip traction. (a) A bump was seen in the gastric fundus (endoscopic ultrasound showed it originated from the muscular layer, 1.5cm in diameter), labeled with Hook Knife. (b) Hook knife cut off most part of the mass along the labeled margin, while the endoscopic transparent cap could not enter into the gap between the lesion and normal tissue, which led to difficulty of the resection. (c) The clip fixed the dental floss right in front of the endoscopic vision. (d) After the traction, the lump was clearly defined by the normal tissue, and the HK knife was easy to peel off the lump. (e) The post-ESD wound has no defect left. (f) The wound was closed with titanium clips. (g) The mass.
