Managing Anticoagulation After ERCP

Risk Assessment and Management

The American Society for Gastrointestinal Endoscopy recommends that apixaban should be delayed for at least 48 hours after ERCP due to the increased risk of post-procedural bleeding, especially if sphincterotomy was performed during the procedure 1, 2
Clinically significant hemorrhage occurs in 0.1-2% of sphincterotomies, with risk factors including bleeding observed during the procedure, coagulopathy, initiation of anticoagulant therapy within 3 days after the procedure, active cholangitis, and low endoscopist case volume 3
The decision to restart anticoagulation should balance the risk of post-procedural bleeding against the risk of thromboembolism, considering factors such as procedural complexity, patient comorbidities, and renal function 1
For high-risk endoscopic procedures, including ERCP with sphincterotomy, anticoagulants should be resumed up to 48 hours after the procedure, depending on the perceived bleeding and thrombotic risks 1, 2
The American College of Cardiology recommends considering bridging with low molecular weight heparin (LMWH) if immediate anticoagulation is necessary for high thrombotic risk patients 1, 6

Endoscopic papillary balloon dilation (EPBD) has been proposed as an alternative to sphincterotomy for biliary stone extraction, with a lower incidence of hemorrhage 3
Post-sphincterotomy bleeding can be immediate or delayed (up to several weeks), with delayed bleeding more common with anticoagulant use 3
The American Society for Gastrointestinal Endoscopy suggests monitoring for signs of bleeding for several days after initiating apixaban, especially in patients with high thrombotic risk 3

For low thrombotic risk patients, apixaban should be delayed for at least 48 hours after ERCP, with consideration of extending to 72 hours if sphincterotomy was performed and there were concerns about hemostasis 1, 2
For high thrombotic risk patients, consider starting with a lower dose of apixaban if initiating earlier than 48 hours, and consult with cardiology for optimal management 1, 6
