Ileal Neobladder With A Continent Cutaneous Catheterizable Channel Using the Extramural Serous Lined (Mansoura)...

Continent cutaneous diversion is an appealing option when orthotopic diversion is not feasible and continence preservation is desired. We describe the surgical technique of creating an ileal w-neobladder with a continent catheterizable channel using the extramural serous lined (Mansoura) principle in a bladder exstrophy patient.

A 9-year-old boy born with classic bladder exstrophy, underwent cystectomy and a sigma rectosigmoid pouch after multiple unsuccessful attempts of exstrophy reconstruction. Colonic diversion was complicated by refractory metabolic acidosis, ureteral obstruction and recurrent pyelonephritis. Ileal neobladder with a continent stoma was recommended after family counseling.

A 50-cm segment of the terminal ileum is isolated. The proximal 7 cm of the isolated segment are partly tailored and used as an afferent limb. The appendix is used for creating the catheterizable channel. The remainder of the ileal segment is fashioned in a w-configuration. Extramural serous-lined tunnels are created between the lateral limbs of the pouch. The appendix and afferent ileal segment are embedded in the serous lined tunnels to achieve continence and antireflux mechanisms, respectively. The ureters are, thereafter, anastomosed to the afferent ileal segment in an end-to-side fashion. Umbilicoplasty was done using the VQZ-plasty technique.

Conversion to an ileal neobladder is an option in patients who suffer the complications of colonic diversion. The extramural serous-lined technique is a versatile technique that can be used for creating antireflux and continence mechanisms.
