<unk>  is inflammation of the ileal pouch, an artificial rectum surgically created out of ileal gut tissue in patients who have undergone a colectomy. The ileal pouch-anal anastomosis is created in the management of patients with ulcerative colitis, indeterminate colitis, familial adenomatous polyposis, or rarely, other colitides. A variety of mechanisms have been proposed, but the precise cause is unclear. The incidence of a first episode of<unk>  at 1, 5 and 10 years post-operatively is 15%, 33% and 45% respectively. Patients with<unk>  typically present with bloody diarrhea, urgency in passing stools, or discomfort while passing stools. The loss of blood and/or dehydration resulting from the frequent stools will frequently result in nausea. Extreme cramping and pain can occur with<unk> . Endoscopic evaluation of the pouch (pouchoscopy) in patients with<unk>  usually reveals erythematous pouch mucosa, loss of pseudocolonic vasculature or other architecture, and friability of the mucosa. Biopsies show evidence of inflammatory cells or red blood cells in the lamina propria.
