Laparoscopic radical cystectomy with extracorporeal ileal conduit urinary diversion for treatment of Chinese bladder cancer patients.

PURPOSE: To present our experience in laparoscopic radical cystectomy with extracorporeal urinary diversion for treatment of Chinese bladder cancer patients. METHODS: Between January 2003 and November 2005, 41 men and 5 women with organ-confined muscle-invasive transitional cell carcinoma of the bladder underwent laparoscopic radical cystectomy with the Bricker-type urinary diversion. The age range was 36-71 years. Laparoscopic radical cystectomy and bilateral pelvic lymphadenectomy were performed using five fan-shaped ports by a transperitoneal approach. An ileal conduit diversion was created through the site of specimen retrieval which was the second port at the region of the right pararectus. RESULTS: 46 radical cystectomies with Bricker-type ileal conduits were performed. No conversion to open surgery was necessary. Mean operating time was 220 min (range 120-249 min) for laparoscopic radical cystectomy and 75 min (range 65-120 min) for creating the ileal conduits. Mean estimated blood loss was 276 ml (range 155-567 ml). Two of the 46 patients needed blood transfusion (400 ml each). Mean days to ambulation and oral intake was 4.1 (range 3-5 days) and 3.5 (range 3-6 days), respectively. Mean hospital stay was 17.6 days (range 12-35 days). Mean follow-up was 6.1 months (range 3-19 months). Histopathological examination of the specimens revealed stage T2N0M0 in 18 cases, T3aN0M0 in 14, T3bN0M0 in 9 and T3bN1M0 in 5 (TNM staging). WHO grading: G1 in 2 cases, G2 in 26 cases and G3 in 18 cases. Pelvic metastases appeared in one case and 44 patients are alive and free of disease. Intravenous pyelogram at 3 weeks postoperatively shows no evidence of upper urinary obstruction in 45 patients. CONCLUSION: Despite technical difficulties, laparoscopic radical cystectomy with Bricker-type urinary diversion is feasible. With more experience in the surgical technique, laparoscopic radical cystectomy with extracorporeal urinary diversion can become an alternative treatment of choice in the selected patients with organ- confined bladder cancer in China.
