Abstract
Endoscopic mucosal resection (EMR) is a safe and effective treatment for large laterally spreading colorectal lesions. The safety and efficacy of EMR follows a key anatomical principle: complete tissue resection of a mucosal lesion above a submucosal fluid cushion to avoid injury to the deeper mural layers. The majority of polyps encountered have low risk of submucosal invasion and are suitably treated by EMR; however, appropriate lesion selection is fundamental to satisfactory patient outcomes. This chapter discusses endoscopic assessment of large colonic polyps, technical aspects of EMR, techniques to manage procedural related complications, and post-procedural follow-up of patients.
