Endoscopic submucosal dissection techniques and technology: European Society of Gastrointestinal Endoscopy (ESGE) Technical Review

“…The multipolar ("spider") system described above is enhanced by the addition of a loop that may be tightened. As the force exerted by the central rubber band decreases as dissection progresses, the loop is tightened thus maintaining the traction force [70][71][72][73].…”

Endoscopic intermuscular dissection of rectal T1 cancer with adaptive traction: use of additional loops to improve traction directly on the circular muscular layer

“…An adaptive traction device that is capable of being tightened to increase traction during the late stages of the procedure (A-TRACT-2 + 2; Hospices civils de Lyon, France) could be useful in these situations ( Fig. 1 , Video 1 ) 4 5 .…”

Endoscopic resection using adaptive traction for a large recurrence after a full-thickness transanal endoscopic microsurgery: improving exposure is a key point for complete removal

“…This lesion invaded the anal verge. An adaptive traction device (A-TRACT 2 + 2, Hospices Civils de Lyon) was used to improve exposure of the area 2 3 4 following the current strategy of setup 5 . After circumferential incision, the first two loops were placed at the oral and anal edges of the target area ( Video 1 ), and initial dissection and trimming were done using only the auto-traction on these two sides.…”
