Delphi consensus statement for the management of delayed post-polypectomy bleeding

Abstract

Background: Delayed post-polypectomy bleeding (DPPB) is the most common adverse event following colonic polypectomy, yet its management remains highly heterogeneous and lacks standardization. A considerable number of colonoscopies performed for DPPB may be unnecessary and do not result in hemostatic intervention. Objectives: To develop evidence-based statements to guide clinical decision-making in DPPB. Design: Multidisciplinary Delphi consensus statement. Methods: A panel of 29 experts in gastroenterology, hematology, radiology, and surgery was assembled. Through a systematic review of the literature and a modified Delphi process, consensus statements were developed through iterative rounds of anonymous voting. Statements were revised following anonymous voting and feedback at each round. Those achieving 80% agreement were accepted. Results: The expert panel reached a consensus on 36 statements, covering areas such as antithrombotic management, bowel preparation, colonoscopy indications, and therapeutic hemostatic modalities. Key recommendations include guidance for managing self-limited bleeding and risk stratification to reduce the rate of unnecessary colonoscopies, as well as recommendations for hemodynamically unstable patients who may require primary angioembolization. A practical clinical algorithm is proposed. Conclusion: This document provides a consensus-based framework for managing DPPB. These recommendations aim to improve patient outcomes and optimize healthcare resources while fostering a standardized approach to this common adverse event.
