Laparoscopic Radical Cystectomy With Intracorporeal Orthotopic Ileal Neobladder: Technique and Clinical Outcomes

ObjectiveTo study the feasibility and safety of laparoscopic radical cystectomy with intracorporeal orthotopic ileal neobladder and to evaluate the role of endoscopic stapling in neobladder construction.Materials and MethodsFifty-five patients with bladder cancer who underwent laparoscopic radical cystectomy were retrospectively examined. Extended pelvic lymph node dissection was performed before cystectomy. An ileal segment of 50 cm was harvested to construct a U-shaped reservoir. The bottom of the reservoir was anastomosed with the posterior urethra. Twenty-five patients underwent neobladder construction by manual suturing and 30 patients by endoscopic stapler suturing.ResultsThe mean operative time was 346 minutes, and mean neobladder construction time was 230 minutes. The median estimated blood loss was 500 mL, and 17 patients received intraoperative transfusion. Postoperative complications included 2 cases of urine leakage, 7 cases of pyelonephritis, 4 cases of incomplete bowel obstruction, 1 case of anastomotic stricture, and 1 case of death. Endoscopic stapler suturing for neobladder construction took significantly less time than manual suturing. However, neobladder stones were found in 2 patients who underwent operation using endoscopic suturing, and the stones were removed cystoscopically. The functional outcomes of the 2 constructive methods were comparable.ConclusionLaparoscopic radical cystectomy with intracorporeal orthotopic neobladder is safe and feasible for experienced laparoscopic surgeons. Application of endoscopic stapler simplifies the surgical procedure while increasing the risk of neobladder stone formation.
