About

Endoscopic resection of pedicled 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 pedicled polyps with different pedicle sizes. Small pedicled polyps with heads smaller than 20mm and pedicles smaller than 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 pedicled polyps may also be a safe resection strategy. However, for small pedicled 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 pedicled polyps may provide a basis for revision of guidelines.
