Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Endoscopic resection of pedunculated polyps mainly focuses on how to prevent bleeding, and also needs to pay attention to the convenience of resection and the integrity of resection, which means that different endoscopic resection strategies should be adopted for pedunculated polyps with different stalk sizes. Small pedunculated polyps with heads smaller than 20mm and stalks less than or equal to 5mm are defined as having a relatively small risk of bleeding. Preliminary studies in recent years suggest that the use of cold snare polypectomy for small pedunculated polyps may also be a safe resection strategy. However, for small pedunculated polyps, ASGE and ESGE guidelines currently recommend hot snare polypectomy in the middle and lower pedicles (evidence level medium). Therefore, the provision of high-quality clinical evidence related to cold resection techniques in the resection strategy of small pedunculated polyps may provide a basis for revision of guidelines.
