Objectives: The flap valve principle is not easily applicable to an ileal pouch since a submucosal tunnel is difficult to create. We attempted to construct an ileal pouch with an umbilical stoma applying the serous–lined principle for both ureteral implantation and construction of a continent valve.Methods: In 9 patients, a continent pouch with an umbilical stoma was created entirely from an ileal segment. Adopting the serous–lined principle, a continent valve was created by appendix in 2 cases, tapered ileum in 3 cases, and reconfigured ileum in 4 cases. These were implanted into the anterior suture line of the pouch and embedded into the serous–lined tunnel formed by the pouch wall.Results: Patients can catheterize the pouch easily with a 14–Fr catheter. Postoperatively, pouch capacity is over 400 ml with complete continence.Conclusion: This technique can provide a simple and effective continent ileal pouch facilitating umbilical anastomosis. As a continent valve, the reconfigured ileal segment seems most useful for application of the serous–lined principle.
