Title: Clip-and-snare method with a pre-looping technique versus conventional method in the
treatment of precancerous lesion and early gastric cancer: a retrospective study
Version: 1 Date: 31 Oct 2023
Reviewer's report:
This is a retrospective single center study comparing conventional ESD with the clip-and-snare
method.
1. How did authors assign the ESD cases to CSM-PLT or conventional method during this study
period? I was not able to find the assignment process.
2. I can understand this method is useful traction method, but why did you not use any other
traction method for any of conventional ESD cases?  Is there any literature that showed CSM
traction is better than others?
3. How long did it take to apply the CSM  in each case? Is there any trouble on attaching the
clip to the lesion?
4. This traction always goes towards the oral side, which may make this traction method inferior
to internal traction methods. Please discuss the superiority of this method compard to internal
traction in which we can decide traction direction.
