Endoscopic mucosal resection of sessile serrated adenomas/polyps (SSA/Ps). (A–C) Note the inconspicuous appearance of all three lesions despite their larger sizes. Submucosal chromogelofusine injection assists with delineating the peripheral extent of the lesion. A margin of normal tissue should be captured during mucosal resection. Thermal ablation of the resection margins with snare tip soft coagulation (effect 4, 80W; VIO 300D; Erbe) reduces the risk of lesion recurrence.
