Initially, it was considered that non-depressed lesions types 0-IIa and 0-IIb with diameters less than 2 cm could be treated safely with endoscopy. For depressed lesions type 0-IIc a limit of 1 cm was established. However, these limits have been changed, and no final agreement has been reached as of this writing Figures 2 and 3.
