Effect of Instruction on Preventing Delayed Bleeding after Colorectal Polypectomy and Endoscopic Mucosal Resection

Background: The frequency of delayed bleeding after colorectal polypectomy has been reported as 0.6–2.8%. With the increasing performance under continuous use antithrombotic agents, care is required regarding post-polypectomy (DPPB). Better instruction to educate endoscopists therefore needed. We aimed evaluate effect and factors associated with endoscopic polyp resection. Methods: This single-center, retrospective study was performed assess in checking complete hemostasis risk for onset DPPB. incidence bleeding, comorbidities, medications were evaluated from medical records. Characteristics historical control patients compared. Results: A total 3318 polyps 1002 evaluated. group comprised 1479 458 after-instruction 1839 544 patients. DPPB occurred 1.1% control, 0.4% after-instruction. Instruction significantly decreased particularly cases agents. Hot polypectomy, clip placement, agents significant independent even instruction. Conclusion: rate check hemostasis. Even instruction, can still occur or hot polypectomy.
