Pouch cancer is a rare disease diagnosed in incidences varying from 0.8 to 3.4% in worldwide FAP series. Male patients, presence of CRC in the RPC specimen, colorectal phenotype, and association with duodenal adenomas are considered the main risk factors. Pouch adenomas develop after both hand-sewn or stapled anastomosis. Pouch polypectomy might prevent the development of adenocarcinomas, as patients under surveillance are diagnosed with more localized diseases.
