CECCHINI ROSELL, Lluís et al. Laparoscopic radical cystectomy in clinically localized (T2) bladder tumors. Arch. Esp. Urol. [online]. 2008, vol.61, n.4, pp.511-516. ISSN 0004-0614.

Objectives: Laparoscopic radical cystectomy has been developed after the expansion of laparoscopic radical prostatectomy. This technique makes possible a minimally invasive approach to muscle-invasive bladder cancer with less blood loss and faster postoperative recovery. Methods: From September 2004 to January 2007, 54 laparoscopic radical cystectomies were performed, 48 of them in stage T2, from which 43 (90%) were male and 5 (10%) female patients. Mean age was 64 years (27-88). Lymphadenectomy was carried out by laparoscopic approach in all cases, with a mean of 13 nodes obtained (4-24). Urinary diversion was done through the incision needed to extract the specimen in all cases but one that was completed completely intracorporeally; constructing a Bricker-type ureteroileostomy in 30 (62%) cases, orthotopic neobladder (Vesica Ileale Padovana) in 17 cases (35%), and cutaneous ureterostomy in 1 case (2%). Results: Mean surgical time for the whole procedure was 287 minutes (180-480), 270 minutes for Bricker-type derivation cases and 316 minutes for neobladder cases. Blood transfusion rate was 25%. Mean ileal paralysis was 5 days (2-10) with a mean hospital stay of 13 days (6-34) for Bricker cases and 16 days (8-30) for neobladder cases. Oncological control, after a mean follow-up of 10,8 months (0,4-30), showed a cancer-specific survival of 90% with a mean survival time of 28 months (95% CI 26-30). Global mean survival was 79% with a mean survival of 26 months (95% CI 23-29). Conclusions: Laparoscopic radical cystectomy is a feasible technique that offers some advantages. It allows excision with less blood loss and an easier postoperative period. Randomized studies should demonstrate these advantages to confirm this approach as the technique of choice. Urinary diversion performed through the laparotomy incision, necessary to extract the specimen, optimizes derivation results and whole surgical time without reducing the beneficial effects of the laparoscopic exeresis.
