Su1489 Safety and Efficacy of Endoscopic Submucosal Dissection for Non-Ampullary Duodenal Neoplasms Using Polyglycolic Acid Felt and Fibrin Glue Sealing With Clips

      Endoscopic submucosal dissection (ESD) of non-ampullary duodenal neoplasms is often technically difficult because unstable scope operation makes it difficult to ensure an adequate field of view. In addition, since bile and pancreatic juice flow out of the papilla of Vater and the duodenal wall is thin, the risk of complications is higher than in other portions of the gastrointestinal tract. Therefore, immediate endoscopic closure is important for preventing postoperative complications such as delayed perforation and post-ESD bleeding secondary to bile and pancreatic juice exposure. Therefore, we suggest a more secure ESD technique for duodenal tumors that utilizes a “pocket-creation method” as well as a polyglycolic acid (PGA) felt and fibrin glue sealing with clips to prevent postoperative complications.
