In this study, we report our stepwise clinical and endoscopic assessment of the patient with an ileoanal pouch.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>The most common configuration of the ileoanal pouch is a J-pouch, and the stapled anastomosis is more frequently performed than a handsewn post-mucosectomy. A structured clinical and endoscopic assessment of the ileoanal pouch must provide information on 7 critical areas: anus and perineum, rectal cuff, pouch anal anastomosis, pouch body, blind end of the pouch, pouch inlet and pre-pouch ileum.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>We have developed a structured pro forma for step-wise assessment of the ileoanal pouch, according to 7 essential areas to be evaluated, biopsied and reported. The structured assessment of the ileoanal pouch in 102 patients allowed reporting of abnormal findings in 63 (61.7%). Strictures were diagnosed in 27 patients (26.4%), 3 pouch inlet strictures, 21 pouch anal anastomosis strictures, and 3 pre-pouch ileum strictures. Chronic, recurrent pouchitis was diagnosed in 9 patients, whilst 1 patient had Crohn\u2019s disease of the pouch.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>Detailed clinical history, assessment of symptoms and multidisciplinary input are all essential for the care of patients with an ileoanal pouch.
