Pouchitis

Pouchitis is an umbrella term for inflammation of the ileal pouch, an artificial rectum surgically created out of ileum (the last section of the small intestine) in patients who have undergone a proctocolectomy or total colectomy (removal of the colon and rectum). The ileal pouch-anal anastomosis is created in the management of patients with ulcerative colitis, indeterminate colitis, familial adenomatous polyposis, cancer, or rarely, other colitides.A variety of mechanisms can be the cause of pouchitis including inflammatory factors such as a disbiosis sparked inflammation or Crohn's disease of the pouch, surgical causes including surgical join leaks and pelvic sepsis, or infectious from Clostridium difficile (C Diff) or Cytomegalovirus (CMV). It is possible to have more than one factor causing pouch inflammation at the same time.The incidence of a first episode of pouchitis at 1, 5 and 10 years post-operatively is 15%, 33% and 45% respectively.Patients with pouchitis 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 pouchitis. Endoscopic evaluation of the pouch (pouchoscopy) in patients with pouchitis 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.
