Published in 2022 at "Surgical Endoscopy"

DOI: 10.1007/s00464-021-08975-0

Abstract: It was not yet fully established whether the use of antiplatelet agents (APAs) is associated with an increased risk of colorectal post-polypectomy bleeding (PPB). Temporarily, discontinuation of APAs could reduce the risk of PPB, but… read more here.
