Title: Clinical impact of the perioperative management of oral  anticoagulants in bleeding after 
colonic endoscopic mucosal resection

Reviewer: Yosuke Tsuji  
 
Reviewer's report:  
 
Thank you for considering my comments for the article BMGE -D-19-00579 entitled 'Clinical 
impact of the perioperative management of oral anticoagulants in bleeding after colonic 
endoscopic mucosal resection. '  
 
 
Major comments:  
 
1. Is the conclusion totally accepted by the authors? Certainly, there is no significant 
difference in bleeding rate between the HBT group and continuous warfarin or one -day 
skip of DOACs, but it does not directly mean that continuous an ticoagulants without 
HBT did not prevent bleeding. Considering this conclusion, it seems that the 
perioperative management of anticoagulants should be reconsidered.  
 
Are the methods appropriate and well described?  
If not, please specify what is required in your comments to the authors.  
 
Yes 
 
Does the work include the necessary controls?  
If not, please specify which controls  are required in your comments to the authors.  
 
Yes 
 
Are the conclusions drawn adequately supported by the data shown?  
If not, please explain in your comments to the authors.

Are you able to assess any statistics in the manuscript or would you recommend a n 
additional statistical review?
