Long-term outcome after urinary diversion using the ileocecal segment in children and adolescents: Complications of the efferent segment

The in situ submucosally embedded appendix and the intussuscepted ileal nipple valve are reliable continence mechanisms in the long-term median follow-up of nearly 16 years. The stomal stenosis rate is approximately double for the submucosal appendix, likely because of its smaller diameter in comparison with the ileal valve. Although we encountered a high overall rate of complications, the satisfaction rate with the diversion was high (99% [88/89] satisfied or very satisfied patients).
