Simplified laparoscopic radical cystectomy with orthotopic ileal neobladder creation in a porcine model.

Background and Purpose: Laparoscopic radical cystectomy with orthotopic ileal neobladder creation is a technically challenging and lengthy surgical procedure. We present our experience with a simplified technique for laparoscopic cystectomy and neobladder creation in the porcine model. Materials and Methods: Ten female minipigs underwent a purely laparoscopic radical cystectomy with orthotopic ileal neobladder creation. Nine ureterointestinal anastomoses were performed using a simplified "dunk" technique, where the ureter was prolapsed 5 mm into the afferent limb and the periureteral tissue was secured to the bowel serosa with three superficial sutures. Six ureters were not stented, and three had indwelling stents inserted. In 11 ureters, the anastomosis was performed using a running mucosa-to-mucosa technique (three with stents, eight without stents). The Lapra-Ty suture clip (Ethicon Endosurgery, Cincinnati, OH) was used to secure the running sutures on the urethra, ureters, and neobladder. Animals were...
