Simplified Indiana pouch with multiple teniamyotomies

Objectives. To describe a retrospective review of a single-institution, single-surgeon (M.G.) experience with 44 simplified Indiana pouch with multiple teniamyotomies without detubularization and reconfiguration. Methods. From April 1999 to May 2003, 44 patients underwent radical cystectomy and continent urinary diversion with a simplified Indiana pouch technique using teniamyotomies without detubularization and reconfiguration. The tenia was sectioned across the whole width and deepened as far as the submucosal layer, with 2 to 3 cm between each teniamyotomy. The efferent tract of the reservoir was prepared using the appendix. If it was unsuitable, an ileum invagination nipple fixed in the ileocecal valve was constructed. Results. The mean follow-up was 3 years (range 1 to 5). Continence was excellent for 40 patients (91%); in 4 patients (9%), daytime incontinence was reported. The urodynamic studies showed an average pressure at 350 mL of capacity of 19.6 cm H2O (range 15.1 to 25.5). The average pressure at maximal capacity (400 to 600 mL) was 32.3 cm H2O (range 28.5 to 35). Long-term complications occurred in 15 patients (34%), with a mean onset of 13.4 months postoperatively. Conclusions. Our experience showed that a modified Indiana pouch with multiple teniamyotomies has a good capacity with low internal pressure and good continence. Thus, even with the comparable results of other continent pouch models, our modified Indiana pouch is a valid alternative because of its simplicity to perform.
