Other related information

When patients taking warfarin undergo high-risk gastrointestinal endoscopic procedures, they need heparin replacement during the perioperative period. In these cases they need to use both of heparin and warfarin after procedures for 3 to 11 days, and very high rate of delayed bleeding has been reported. When patients take NOAC during the perioperative period, they don't need use heparin after endoscopic procedures, therefore decrease in delayed bleeding rate is expected.
