Incidence of Dysplasia in Pelvic Pouches in Pediatric Patients After Ileal Pouch-Anal Anastomosis for Ulcerative Colitis

Abstract

Similar morphologic changes can be seen in ileal pouches in pediatric and adult patients. There seemed to be no increased risk of dysplasia in children and young adults who had undergone ilial pouch-anal anastomosis surgery for ulcerative colitis during a 5 year follow-up. Because the long-term risk of development of dysplasia is unknown, an initial screening should be performed 5 years after the creation of a pelvic pouch in children or when the total disease duration exceeds 7 years. Once identified, patients with Type C mucosa should have annual screening for dysplasia until further data become available.
