The Risk of Bleeding After Removal of Large Colorectal Polyps in Patients Taking Aspirin

Summary

The risk of bleeding after polypectomy of large colorectal polyps in patients taking aspirin is uncertain. This is a randomized, multi-center, placebo-controlled, double-blind study to compare the risk of significant bleeding after endoscopic polypectomy of large (\>=10mm) colorectal polyps in patients continuing or discontinuing on daily acetylsalicylic acid (ASA) use. Eligible patients will be randomly assigned in a 1:1 ratio to a group taking 75mg daily ASA or placebo 7 days before and 14 days following polypectomy. The primary endpoint of the study is bleeding within 30 days from colorectal polypectomy. The secondary endpoints are composite cardiovascular events occurring between the date of randomization and 30 days after polypectomy.
