How I remove polyps larger than 20 mm.

The net effect is precise and clean tissue excision, limited thermal injury to the submucosal bed beneath the lesion, and sharp crisp mucosal incision margins where the lesion has been removed, which facilitates subsequent evaluation for potential residual adenoma. I inspect the mucosal defect after every resection for adequacy of resection and DMI (Fig. 2 Endoscopic views showing: a - c a 40-mm 0-IIa granular lesion treated with wide-field endoscopic mucosal resection; d - f endoscopic mucosal resection (EMR) of a 90 % circumferential 0-IIa + Is granular lesion, with snare-tip soft coagulation applied to the margin of the post-EMR defect at completion of the procedure for the prevention of adenoma recurrence.
