“…The margins of the lesion were delineated using i-SCAN digital contrast (Pentax, Tokyo, Japan) on a therapeutic colonoscope (E34i10). An adaptive traction device (A-TRACT 2 + 2; Hospices Civils de Lyon) was used to improve the exposure of the area 2 3 4 , according to the current setup strategy 5 . After a circumferential incision with large margins (to fix the clips onto normal tissue) had been made, the first two loops were placed at the oral and anal edges of the target area ( Video 1 ), then the two additional loops were placed on the two side edges and the rubber band was fixed to the opposite wall to get 90° traction.…”
