[...]the stability of traction is questionable at times; incorrect clip(s) placement may further deteriorate the quality of traction, which sometimes necessitates placement of additional clips. Factors such as patient's abdominal wall thickness would adversely affect traction force achieved by the magnetic anchor technique; a modified internal magnetic traction technique using an internal device to replace the external magnet has been reported in a porcine model. [...]the clinical applicability of these special traction techniques remains an area for future development. The characteristics of each traction technique should be considered in the context of their complexity, and the optimal technique should be chosen considering the anatomical location of ESD, resource availability, and physician expertise in employing the chosen technique (Table 1, see Table and Video, Supplementary Digital Content 1, http://links.lww.com/CTG/A477 and http://links.lww.com/AJG/B872)....
