    48-years-old male with familial adenomatous polyposis(FAP), underwent proctocolectomy and ileal-pouch-anal-anastomosis(RPC-IPAA) in 2004. He presented with rectal bleeding. Endoscopy showed multiple coalescent polyps occupying the anal transitional zone and anastomosis. ESD revealed severe fibrosis, surgical clips at the anastomosis, some of which were removed. En-bloc complete excision of the remaining rectal mucosa was achieved.

    ESD is effective for complete resection of lesions associated with severe fibrosis as in peri-anastomotic sites. We report the first case of ESD for anal transitional zone lesions after RPC-IPAA in a patient with FAP, which may still leave mucosa prone to neoplasia requiring anual endoscopic surveillance.
