Restorative proctocolectomy with ileal pouch-anal anastomosis is currently the preferred
surgical treatment for most patients suffering from ulcerative colitis or familial
adenomatous polyposis coli. The double-stapled technique of transection of the proximal
anal canal and anastomosis has proven to be technically easier and to provide better
functional outcomes than mucosectomy and hand-sewn pouch-anal anastomosis at the dentate
line. Concerns regarding the development of rectal carcinoma or dysplasia in the cuff
of retained rectal mucosa have not been realized.
