Background: This study aimed to describe perioperative, oncological and learning curve outcomes for robotic-assisted radical cystectomy (RARC) across the first 100 cases performed by an Australian high-volume, fellowship-trained robotic surgeon.
Methods: A retrospective cohort study was performed on a consecutive group of 100 patients who underwent RARC between 2010 and 2016 in Brisbane, Australia. Perioperative, oncological and survival data were collected. Demographic, survival and learning curve analyses were performed in MedCalc.
Results: A total of 100 patients underwent RARC over the study period. Median operative time was 389 min, with a reduction in median times from 420 to 330 min when comparing the first 50 versus the second 50 patients (P < 0.001). Median estimated blood loss was 500 mL, while urinary diversion was performed extracorporeally in 20 patients, intracorporeally in 69 patients and using a hybrid technique in 11 patients. Median length of hospital stay was 11 days. Post-operative complications occurred in 56% of patients (Clavien-Dindo classification I-II 32%, III-V 24%). Positive operative margins were 2% and median lymph node yield was 21 nodes. Overall recurrence-free survival was 50.3 months.
Conclusion: Initial short-term experience with RARC shows favourable outcomes with regard to operative, perioperative and pathological indicators compared to open radical cystectomy and other RARC series.
