Objective: We present our preliminary experience with laparoscopic radical cystoprostatectomy and continent orthotopic neobladder performed extracorporeally. We believe that this surgical approach combines the advantages of minimally invasive laparoscopy with the speed and safety of open surgery. Material and Method: Between June and September 2002, 5 male patients underwent to laparoscopic radical cystoprostatectomy and continent orthotopic neobladder performed extracorporeally. Average age was 50.6 years (range: 29-70). The operative indication was muscle-invasive carcinoma of the urinary bladder in 4 patients. One of these 4 patients was previously treated with radiotherapy. Our technique has 3 steps. Cystoprostatectomy and pelvic lymph node dissections are performed laparoscopically using five ports by a transperitoneal approach. We remove the surgical specimens through a 5 cm infraumbilical incision and through the same incision an ileal loop is extracted from the abdominal cavity, isolated, detubularized and neobladder is reconfigured. Finally, urethro-neobladder anastomosis is formed with laparoscopic technique. Results: Surgical technique was reproduced in all 5 patients. Mean operative time was 5.4 hours (range: 4.5-7). Mean blood loss was 410 ml (range: 200-800) and not transfusion was indicated. Mean hospital stay was 6.8 days (range: 5-12). Conclusion: Laparoscopic radical cystectomy is feasible when surgical team has experience in laparoscopic surgery. The most technically demanding steps of the procedure are neobladder confection and ureteral neoimplante, which are performed extracorporeally. We believe that with our combined approach, this technique is completely reproducible
