Objectives: Evaluation of the results and complications of the technique by endoscopists of a reference center. Review of indications and limitations of the technique. Material and methods: Descriptive, retrospective and observational analysis of patients treated with endoscopic mucosal resection technique at a referral center in Lima, Peru, between January 2004 and December 2018.EMR Technique was used in polypoid lesions greater than 1 cm.
