Management and Outcomes of Bleeding Within 30 Days of Colonic Polypectomy in a Large, Real-life Multicenter Cohort Study.

Management of delayed (within 30 days) post-polypectomy bleeding (DPPB) has not been standardized. Patients often undergo colonoscopies that do not provide any benefit. We aimed to identify factors associated with therapeutic intervention and active bleeding after DPPB.We performed a retrospective study of 548 patients with bleeding within 30 days after an index polypectomy (DPPB; 71.9% underwent colonoscopy, 2.6% primary angiographic embolization, and 25.5% were managed without intervention) at 6 tertiary centres in Spain, from January 2010 through September 2018. We collected demographic and medical data from patients. The primary outcomes were need for therapeutic intervention and the presence of active bleeding during colonoscopy.A need for therapeutic intervention was independently associated with the use of anti-thrombotic agents, haemoglobin decrease > 2 g/dL, haemodynamic instability, and comorbidities (P
