* Two lesions were analyzed from this patient.
† Paris Endoscopic Classification of Superficial Neoplastic Lesions (Gastrointest Endoscopy 2003;58[suppl.]:S3-S27).
‡ Preinvasive lesions were classified as tubular adenomas (TA), tubulovillous adenomas (TVA), villous adenomas (VA), microvescicular serrated polyps (MVSP), serrated adenomas (SA), sessile serrated adenomas (SSA). In parentheses, the degree of dysplasia (none, low, high) is reported based on the WHO classification of tumors of the digestive system (Editorial and consensus conference in Lyon, France, November 6–9, 1999 [IARC]).
