title: Endoscopic submucosal dissection to treat ileal high-grade dysplasia after ileoanal anastomosis for familial adenomatous polyposis: report of a case.
abstract: Restorative proctocolectomy has become the most common surgical option for familial adenomatous polyposis patients, based on the premise that the technique yields good functional results and reduces colorectal cancer risk. However, several adenomas may develop in the pouch mucosa in later years, and even cancer (at the anastomosis or in the pouch mucosa) has been reported. Endoscopic submucosal dissection (ESD) would then be indicated, even if severe fibrosis extended into the submucosal layer. Endoscopic resection of an ileal tumor from the thin wall of the ileum carries a high-risk of perforation. Our present case demonstrates the successful use of ESD to treat an ileal neoplasm, a technically difficult lesion with a high-risk of complications.
