Official title
P2Y12 Inhibitor Versus Aspirin Monotherapy in Patients Undergoing Elective Screening and Surveillance Colonoscopy
Overview
Patients on dual antiplatelet therapy )aspirin plus a P2Y12 inhibitor \[clopidogrel, prasugrel, or ticagrelor\]) undergoing screening or surveilance colonoscopy are at increased risk for bleeding from the procedure. Patients are ussually asked to stop the P2Y12 inhibitor for the procedure. Currently, recommendation is that patients only on a P2Y12 inhibitor be changes to aspirin for the procedure. This pilot study will evaluate if there is a large difference in bleeding between patients only taking aspirin compared with patients only taking a P2Y12 inhibitor. Patinets who participate will randomly be randomly asked to stop either aspirin or the P2Y12 inhibitor 1 week before the procedure. Periprocedural bleeding and bleeding after the procedure for iup to 30 days.
Interventions
- Drug Aspirin
Participant will be on aspirin alone or P2Y12 inhibitor alone - Drug P2Y12 inhibitor (clopidogrel, ticagrelor, prasugrel)
Participant will be taking either P2Y12 inhibitor at time of colonoscopy
Primary outcome measures
- Primary safety endpont [Time frame: 7 days]
