Continent ileal pouch using the serous-lined principle

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. Copyright (C) 2000 S. Karger AG, Basel.
