Use of a Modified Continent Ileovesicostomy in Adults with Prior Enterocystoplasty

To describe our initial experience with a novel modification of the Mitrofanoff conduit technique utilizing the Yang-Monti ileovesicostomy and the serosa lined extramural tunnel of the T-pouch to create a continent catheterizable stoma in patients with a prior enterocystoplasty.

A 14 cm segment of bowel was harvested, and the distal 4 cm was divided and reconfigured utilizing the Yang-Monti technique. The remaining segment was folded into a U and secured with a serosal basting stitch. Half of the Yang-Monti tube is laid in the trough of the U-shaped segment and secured. Next, the U-shaped segment was incised along the anti-mesenteric border for the length of the tube. The newly created flaps adjacent to the tube was then laid over the tube and sutured together completing the serosa lined tunnel. The entire patch was anastomosed to a cystostomy through the previous enterocystoplasty. Finally, the proximal end of the tube was brought through the umbilicus and matured as a stoma.

Two patients with prior enterocystoplasties underwent the procedure described above. At follow-up of 18 and 24 months, both patients reported excellent continence. To date, there have been no revisions or significant complications.

The construction of continent catheterizable stoma in adults with prior history of enterocystoplasty presents many technical challenges. The combination of the Yang-Monti ileovesicostomy and the extramural tunnel of the T-pouch provides an effective option for creating a continent catheterizable stoma in adults with prior history of enterocystoplasty.
