A case of an embedded clip in the gastric wall after shielding a post-endoscopic submucosal dissection ulcer with polyglycolic acid sheet.

Takimoto et al first reported a novel endoscopic tissue shielding method using polyglycolic acid sheets (PGA) and fibrin glue in 2012. Since that time, it has been reported to be a safe and effective method to prevent complications after endoscopic submucosal dissection (ESD) ; however more data is needed regarding associated adverse events.
