Clip Dislodgement After Full-Thickness Endoscopic Resection Device Removal of Scarred Gastric Subepithelial Lesion Leading to Delayed Perforation

Endoscopic full-thickness resection using a full-thickness resection device is a newer technique for endoscopic removal of submucosal lesions not amenable to endoscopic mucosal resection or endoscopic submucosal dissection. There is a low rate of complications reported, although we report 2 cases of delayed perforation caused by dislodgement of a full-thickness resection device clip after removal of scarred gastric lesions. Both were managed endoscopically with good outcomes. However, special attention and consideration of alternative closure techniques should be considered with scarred gastric lesions and possible changes to the clip design could be considered.
