Comparison of Oncological and Functional Results of Open and Robot- Assisted Laparoscopic Radical Cystectomy for Bladder Cancer

Özet

Introduction: To assess oncological and functional outcomes of two techniques for patients with bladder cancer who undergone open radical cystectomy (ORC) or robot- assisted radical cystectomy (RARC). Methods: 47 patients who underwent ORC and RARC due to bladder cancer between 2009 and 2017 were evaluated. Preoperative, operative and postoperative follow-up data was recorded prospectively and analyzed retrospectively. Preoperative and postoperative data were compared using Student Paired t test and Mann-Whitney U test. Surivival of the patients were analyzed using Kaplan-Meier test. Results: 34 patients underwent ORC and 13 patients underwent RARC. The mean age of ORC and RARC groups were 61.7 and 62, respectively (p=0.904). The mean operating time (6 hours) in the ORC group was statistically significantly shorter than the RARC group (7 hours). Estimated blood loss was statistically significantly higher in the ORC group [350 (100-800)] than that in the RARC group [150 (100-400)] (p=0.001). The postoperative complication rates were similar between the two groups (p>0.05). There was no statistically significant difference between two groups in terms of hospital stay (p=0.596), rates of positive surgical marginand number of removed lymph nodes (p>0.05). The mean overall survival time was 42.7 months in the ARS group and 51.3 months in the RARC group (p=0.893). Discussion and Conclusion: Robot- assisted radical cystectomy has comparable oncological outcomes to ORC. Although ORC has a shorter operating time, RARC has advantages in term of less blood loss and earlier start of oral feeding.
