Predictive Value of Magnification Chromoendoscopy for Diagnosing Invasive Neoplasia in Nonpolypoid Colorectal Lesions and Stratifying Patients for Endoscopic Resection or Surgery

Abstract

The endoscopic pit pattern on MCE has only a moderate predictive value for nonneoplastic lesions, so that leaving these flat hyperplastic lesions in place on the basis of the endoscopic magnification appearance alone cannot be generally recommended. However, MCE has a good predictive value for guiding management toward either endoscopic resection (if technically feasible) or surgical resection.
