Background: Cryotherapy is a method of endoscopic mucosal ablation that involves delivery of a cryogen to result in tissue destruction by extreme low temperature.Its effects are influenced by the dosage of cryogen and thawing of ice.There are limited data on the tissue effects of multiple freeze and thaw cycles of carbon dioxide (CO2) cryotherapy on GI tissues.
