Aspirin endoscopy: practical clinical approach

This page focuses on Aspirin endoscopy with emphasis on decisions that change patient care, common pitfalls, and the current evidence base.

External guidance for Aspirin endoscopy

Clinical takeaway: For Aspirin endoscopy, decisions should integrate current guidelines, patient-specific risk, and the evidence summarized below.

Answer first: For most GI endoscopic procedures, aspirin used for secondary cardiovascular prevention should be continued. The 2022 ACG-CAG guideline suggests against interruption of aspirin monotherapy for secondary prevention in elective endoscopy. Stopping aspirin can increase cardiovascular risk, while the incremental bleeding risk is modest for most procedures. Exceptionally high-risk interventions may justify individualized discussion, but routine aspirin cessation before standard colonoscopy, biopsy or most polypectomy is poor practice.

Why aspirin is usually continued

Platelet inhibition persists for days after stopping aspirin, while cardiovascular protection is lost. For most endoscopic procedures the bleeding penalty is smaller than the thrombotic penalty.

Primary prevention is different

Aspirin used without established cardiovascular disease may be easier to interrupt when bleeding risk is unusually high.

Dual antiplatelet therapy needs cardiology context

Do not stop both agents after recent coronary stenting without specialist input.

Practical clinical algorithm

1. Confirm why the patient takes aspirin.

2. For secondary prevention, continue aspirin through most endoscopic procedures.

3. Assess whether a planned procedure is exceptionally high risk.

4. If dual therapy is present, coordinate any P2Y12 interruption with cardiology.

5. Restart promptly if aspirin was interrupted.

Common mistakes to avoid

Stopping aspirin before routine colonoscopy.
Treating primary- and secondary-prevention aspirin identically.
Stopping both drugs after recent coronary stenting.
Failing to document the cardiovascular indication.
Delaying aspirin restart after hemostasis.

Trainee takeaway

For most endoscopy, secondary-prevention aspirin stays on board; unnecessary interruption creates preventable thrombotic risk.

Frequently asked questions

Can aspirin be continued for polypectomy?

Usually yes.

What if the patient had a recent coronary stent?

Do not alter antiplatelet therapy without cardiology input.

What about aspirin used only for primary prevention?

Interruption may be more reasonable when procedural bleeding risk is high.
