RESUMEN
PURPOSE: To evaluate peri- and postoperative morbidity, and long-term oncologic and functional results of our laparoscopic radical cystectomy (LRC) technique, comparing it with our standard open approach. METHODS: Between 2000 and 2010, 54 patients underwent LRC for urothelial cell carcinoma of the bladder in two academic hospitals. The procedures were performed by two surgeons. Patients were matched 1:1 with patients who underwent open RC in the same years by the same surgical team. Differences in peri- and postoperative complications across the two groups were assessed using Wilcoxon's rank-sum or χ (2) test. Kaplan-Meier curves, log-rank tests and Cox regression models were constructed to assess differences in recurrence-free survival on long-term follow-up between the two groups. RESULTS: Laparoscopic radical cystectomy was significantly associated with lower blood loss (p < 0.0001) and less frequent postoperative ileus (p = 0.03). Regarding more serious postoperative complications, no difference was found across the two cohorts. Median oncologic follow-up was 42 months (IQR 12-72 months) in the LRC cohort and 18 months (IQR 8-27 months) in patients undergoing open radical cystectomy (ORC). No statistically significant difference in recurrence-free survival was observed between the two groups (log rank p = 0.677). On univariate Cox regression, the surgical approach used was not significantly associated with risk of recurrence. CONCLUSIONS: We found that LRC is safe and associated with lower blood loss and decreased postoperative ileus compared with ORC. Moreover, on long-term oncologic follow-up, LRC appeared non-inferior to ORC with no significant difference in recurrence-free survival. Nonetheless, these results must be confirmed by larger series and stronger long-term follow-up data are needed.
