Application of novel endoloops to close the defects resulted from endoscopic full-thickness resection with single-channel gastroscope: a multicenter study

Background The key step of the endoscopic full-thickness resection (EFTR) procedure is the successful closure of any gastric wall defect which ultimately avoids surgical intervention. This report presents a new method of closing large gastric defects left after EFTR, using metallic clips and novel endoloops by means of single-channel endoscope.
