Effects of Different Endoscopic Treatment Methods on Bleeding Complications in Pedunculated Colorectal Polyps.

Abstract

Introduction: Endoscopic resection of colorectal polyps offers several advantages, including ease of performance, reduced surgical time, and preservation of anatomic structures. However, bleeding remains a common complication of the endoscopic treatment of colorectal polyps, particularly with a higher incidence of postprocedural bleeding in pedunculated colorectal polyps. Currently, there is no optimal method for the resection of pedunculated colorectal polyps. The aim of this study was to compare the postresection bleeding outcomes of 3 different techniques for the removal of pedunculated colorectal polyps.

Methods: A retrospective analysis of postresection bleeding following the use of 3 techniques-endoscopic mucosal resection, endoscopic submucosal dissection (ESD), and prophylactic clips was conducted on pedunculated colorectal polyps.

Results: The incidence of delayed hemorrhage after endoscopic mucosal resection resection of pedunculated colorectal polyps was highest (18.9%). In contrast, the incidence rates of delayed bleeding in the ESD and prophylactic clip groups were 4.3% and 5.9%, respectively (P<0.05). The intraoperative bleeding rate was highest in the ESD group (6.5%), while no intraoperative bleeding occurred in the other 2 groups, indicating a statistically significant difference among the 3 groups (P<0.05). However, the need for endoscopic hemostasis due to delayed bleeding was not significantly different among the groups (P>0.05).

Conclusion: Employing endoscopic submucosal dissection (ESD) and clamping the stalk of pedunculated polyps before removal can effectively reduce the risk of postpolypectomy bleeding. Furthermore, ESD offers distinct advantages for the removal of larger polyps, both at the stalk and the head.
