Tate et al reported the Sydney EMR Recurrence Tool (SERT) for predicting recurrence following endoscopic mucosal resection of a colonic adenoma. The authors are from the University of Sydney and multiple otherinstitutions in Australia.
Patient selection: status post endoscopic mucosal resection (EMR)
Parameters:
(1) diameter of a lateral spreading lesion (LSL) in mm
(2) intraprocedural bleeding requiring endoscopic control
(3) high grade dysplasia
