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.
