Conventional colonoscopic snare polypectomy for large polyps with stalk diameter of 1.5 cm or more carries a significant risk of haemorrhage after transection, probably due to "leak currents". The use of a return-electrode applied to the base of the polyp after snaring instead of the conventional patient-plate permits bi-polar polypectomy which is both safer and more efficient.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
