Abstract
A lot of adverse event were happened after endoscopic resection for nonampullary duodenal tumors. We suggest that useful of PGA sheets and fibrin glue these two studies. ［Case 1］ The patient was a 77-year-old man. Endoscopic mucosal resection was performed for a type 0-IIa lesion located in 2nd portion of duodenum. A PGA sheet was applied to the opening of the ulcer base after resection via biopsy forceps, after which fibrin glue was applied. ［Case 2］ The patient was a 53-year-old man. Endoscopic submucosal dissection was performed for a type 0-IIc lesion located in 2nd portion of duodenum. The ulcer was covered the same way as described for Case 1. These cases indicate that shielding method with PGA sheets and fibrin glue can be effective and safe to prevent adverse events such as delayed bleeding and perforation after endoscopic resection for nonampullary duodenal tumors.
