Reopenable clip over line method for the closure of full-thickness defect after gastric endoscopic full-thickness resection

Abstract

In recent years, the efficacy of endoscopic full-thickness resection for submucosal tumors has been reported [1] [2]. However, a reliable closure method for large full-thickness defects in the stomach remains unclarified. We developed the reopenable clip over line method for closing the mucosal defect after endoscopic submucosal dissection using reopenable clips and a line placed at the muscle layer and edge of the mucosal defect [3] [4] [5]. We report a new method of this type of closure of a 25-mm full-thickness defect in a porcine model ([Video 1]).
