Optimal time of resuming anticoagulant after endoscopic sphincterotomy in patients at risk for thromboembolism: a retrospective cohort study.

There was no significant difference in the incidence of post-EST delayed bleeding according to the resuming time of anticoagulant. Since long cessation of anticoagulant could increase the risk of thrombotic adverse events, the early resumption of anticoagulant seems to be preferred.
