Given the development of advanced endoscopic treatment techniques and the increased number of people taking antithrombotic drugs, measures for managing several complications involving perforation and postbleeding are required. Endoscopic wound closure is indicated for iatrogenic perforation and prevention of complications after resection. At present, various measures, which include endoscopic closure using hemoclips and the sheet covering method, are used. Endoscopic closure for the artificial wound is ideal because “wound closure” is the basis of the surgical field. However, there are several issues regarding reliable endoscopic closure, including the technical limitation of one arm versus single forceps and cost-effective device. In particular, the thick stomach wall makes wound closure more difficult, and the possible formation of a submucosal pocket after mucosal closure can result in insufficient closure. Herein, we introduce a novel endoscopic closure method using the O-ring and ring thread.
