Endoscopic full-thickness resection of gastric tumors using a novel grasp-and-snare technique: feasibility in ex vivo and in vivo porcine models

Abstract

EFTR of gastric tumors using the grasp-and-snare technique is feasible in pigs. This technique is advantageous in that eversion of the gastric wall avoids injury to external organs, continuous luminal insufflation is not required, and the involved techniques are familiar to endoscopists. Additional research is necessary to further evaluate safety and reliable closure.
