Purpose:
We present our technique of laparoscopic ileal conduit creation after cystoprostatectomy in a porcine model performed in a completely intracorporeal manner.
Methods And Methods:
After developing the technique in 5 acute animals laparoscopic cystoprostatectomy with intracorporeally performed ileal conduit urinary diversion was performed in 10 surviving male pigs. A 5-port transperitoneal technique was used. All steps of the technique applied during open surgery were duplicated intracorporeally. Specifically cystectomy, isolation of an ileal conduit, restoration of bowel continuity and mucosa-to-mucosa stented bilateral ileoureteral anastomosis formation were performed by exclusively intracorporeal laparoscopic techniques.
Results:
Surgery was successful in all 10 study animals without intraoperative or immediate postoperative complications. Blood loss was minimal and average operative time was 200 minutes. Stenosis of the end ileal stoma specifically at the skin level was noted in 6 animals. Three deaths occurred 2 to 3 weeks postoperatively. At sacrifice renal function was normal in all surviving animals. No ileo-ureteral anastomotic strictures were noted on pre-sacrifice radiography of the loop or at autopsy examination of the anastomotic sites.
Conclusions:
Laparoscopic ileal conduit urinary diversion after cystoprostatectomy may be performed completely intracorporeally in the porcine model. Clinical application of this technique is imminent.
