.Abstract
Objectives
To report the results of the first quantitative synthesis of literature data from
studies comparing Single-Port Robot-Assisted Radical Prostatectomy performed using
the novel SP surgical platform (SP-RARP) versus RARP performed by using multi-arms
robotic systems.
Methods
Studies comparing the use of da Vinci SP versus that of other available multi-arms
da Vinci platforms were eligible for inclusion in the present review. From selected
studies, data were extracted by using a standardized data extraction form. Patients
baseline demographics and disease characteristics and perioperative variables of interest
for the present review (operative time, blood losses, complications, length of stay
and positive surgical margins rate) were noted whenever available. Weighted mean difference
(WMD) was used as a summary measure for continuous outcomes, whereas the odds ratio
with 95% confidence interval (CI) was calculated for binary variables. Pooled estimates
were calculated by using the random-effect model to account for clinical heterogeneity.
Statistical analysis was performed using Review manager 5.3 (Cochrane Collaboration,
Oxford, UK).
Results
Four comparative studies were retrieved, analysing a total of 610 patients. Baseline
characteristics of treatment groups were statistically similar. No significant differences
were found when comparing SP-RARP versus multi-arms robotic systems in terms of operative
time, blood losses, complications rate and positive surgical margins. Conversely,
SP-RARP was found to allow for a shorter hospital stay (WMD = -0.79 days, 95% CI = -1.07;
-0.52, P-value < .001).
Conclusion
The adoption of the SP platform for duplicating the technique of minimally-invasive
RARP appears to be safe and feasible.
