Querijn N. E. van Bokhorst et al. Delayed post-polypectomy bleeding following cold snare polypectomy of lesions <10mm in patients on high-dose antithrombotic therapy: insights from a Dutch colonoscopy cohort

This retrospective cohort of 31 325 colonoscopies from two Dutch centers assessed the safety of continuing antithrombotic therapy (ATT) during low-risk polypectomies (<10 mm, cold snare). Delayed bleeding was rare (0.09%) and comparable for patients continuing high-versus low-dose ATT (0.58% versus 0.30%; P = 0.61). The number of patients needed to discontinue high-dose ATT to prevent one case of delayed bleeding was 150. The findings support continuation of high-dose ATT for colonoscopy indications with a low risk of detecting advanced polyps.
