The guide-wire technique improves the primary success rate for biliary cannulation during ERCP but does not reduce the incidence of PEP compared to the conventional contrast technique. The incidence of PEP increases incrementally with each attempt at the papilla.
This article has an accompanying continuing medical education activity, also eligible for MOC credit, on page e16 (https://www. gastrojournal.org/cme/home). Learning Objective: Upon completion of this CME activity, successful learners will be able to (1) identify key aspects of colonic endoscopic mucosal resection (EMR), (2) recognize the limitations of piecemeal resection, (3) explain how ablation of the post-EMR mucosal defect can mitigate those limitations, and (4) evaluate the future implications of these findings.
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.
