Table 1 Advantages and disadvantages of the traction endoscopic submucosal dissection methods
Traction
Other advantagesOther disadvantages
PushControl of directionControl of tension
ESD with traction in upper gastrointestinal tract
Clip-with-line method[8,11-14]--+Simple, easy
Percutaneous-traction method[15-18]+++RegraspingInvasive
Magnetic anchor method[19,20]+++Large and expensive
External forceps method[21,22]+-+Regrasping, no need of assistant to hold the forcepsCare of mucosal damage
Internal traction method[23-25]---EasyRoll back of mucosa
Spring-assisted ESD[26]---Easy
Double-channel-scope method[28]+++RegraspingSynchronous movement of forceps and scope
R-scope[29-31]+++Regrasping, swing of knifeThicker and heavier scope, synchronous movement of forceps and scope
Outerroute method[33-38]+++RegraspingSynchronous movement of forceps and scope, small distance between forceps and knife
Double-scope method[10]+++RegraspingInterference of scopes, two light sources, double manpower
Morita[39]+++Regrasping, a little interference of scopesThicher overtube, two light sources, double manpower
Higuchi[40]+++Regrasping, one light sourceInterference of scopes, double manpower
Robot-assisted method[42-44]+++RegraspingMore complicated, no response of hemostasis
ESD with traction in colon and rectum
Sinker-assisted method[45]--+EasyRetreival of scope
External forceps method[46]+-+RegraspingRetreival of scope, only rectum
Internal traction method[47-50]---Easy
Outerroute method[51]+++RegraspingSynchronous movement of forceps and scope
Double-scope method[52,53]+++RegraspingTwo light sources and double manpower, interference of t scopes, lesions in only sigmoid colon and rectum
Fusaroli[54]+++Regrasping, much cheaper, one light sourceinterference of scopes, lesions in only sigmoid colon and rectum
Endoscopic surgical platform[55]+++Regrasping, freedom offering surgical triangulationmore complicated configuration with fixed instruments, only rectum
