The endoscopic resection is the procedure that allows to remove cancerous or precancerous conditions of digestive tract. Endoscopic resection can be preformed by several techniques:

1. Endoscopic mucosal resection (EMR): it allows to remove mucosal lesions
2. Endoscopic submucosal dissection: it allows to remove mucosal lesions that involved submucosal layer and large lesions
3. Full-thickness resection: it allows to remove infiltrating lesions by the resection of a little piece of the entire gastrointestinal wall

the en bloc resection is the ability to remove the neoplasia in a single piece

the complete resection is the ability to remove the neoplasia with clear margins (R0)

recurrence is the recurrence of the neoplasm at the resection site during follow-up

complication rate, early or late, related to the procedure used for endoscopic resection
