Long-Term Followup of the Intussuscepted Ileal Nipple and the In Situ, Submucosally Embedded Appendix as Continence Mechanisms of Continent Urinary Diversion With the Cutaneous Ileocecal Pouch (Mainz Pouch I)

Abstract

Of stomal complications 63% were treated endoscopically. The higher rate of stomal stenosis with the appendiceal stoma is most likely due to the smaller diameter of the appendix. The higher rate of stone formation in patients with the intussuscepted ileal nipple is related to metal staples. Continence rates of the 2 outlets are good with somewhat larger amounts of mucous secretion from the larger stoma of the intussuscepted ileal nipple.
