Iron-deficiency anemia as presentation of pouchitis.

Goals: This study sought to describe the percentage and cause of anemia in patients who underwent ileal pouch with anal anastomosis (IPAA) for ulcerative colitis (UC), and to compare the distribution of complications in patients with and without anemia, especially pouchitis, after IPAA.

Background: IPAA is the surgical procedure of choice for UC. Complications include pouchitis (40%), strictures (30%), small bowel obstruction (10%), pelvic sepsis (<5%), and urinary and sexual dysfunctions (<5%).
