Prevention of delayed bleeding after resection of large colonic polyps.

ABSTRACT

A significant problem encountered in the resection of large, complex colonic polyps is delayed bleeding. This can occur up to two weeks after the procedure and is a significant source of comorbidity. Untreated it can prove life threatening. It is therefore a priority of modern endoscopy to develop and employ techniques to minimaize this. In this article we will review and discuss the evidence base and controversies in this field, with cold EMR technique, Post-EMR clip closure, and topical haemostatic agents.
