Endoscopic mucosal resection in the colon: A practical guide

Endoscopic mucosal resection (EMR) is an important therapy for large sessile lesions and advanced mucosal neoplasia of the colon. Careful pre-resection assessment against established classification systems including Paris and lesion granularity is mandatory to formulate a treatment plan, predict technical success and stratify for the risk of invasive disease. Lesions at high risk for invasive disease are best removed en bloc and this finding may dictate a change in the therapeutic strategy. Meticulous technique is crucial to maximise procedural success. This chapter will provide a comprehensive step by step approach to colonic EMR including equipment selection, lesion assessment, endoscopic technique, post procedural care and early detection and management of complications.
