Incidence of microscopic residual adenoma after complete wide-field endoscopic resection of large colorectal lesions: evidence for a mechanism of recurrence

Endoscopic mucosal resection (EMR) of large ( ≥2 cm) nonpedunculated colorectal polyps (LNPCP) is associated with high rates of recurrent/residual adenoma, possibly due to microadenoma left at the margin of resection. Data supporting this mechanism are required. We aimed to determine the incidence of residual microadenoma at the defect margin and base after EMR.
