Prospective Comparison Between the AirSeal® System Valve-Less Trocar and a Standard Versaport™ Plus V2 Trocar in Robotic-Assisted Radical Prostatectomy

2013 
Abstract Background and Purpose: To prospectively compare the AirSeal® System valve-less Trocar with a standard Versaport™ Plus V2 Trocar as assistant insufflating port in transperitoneal and extraperitoneal robotic-assisted radical prostatectomy (t-RARP/e-RARP). Patients and Methods: Two consecutive cohorts of patients undergoing RARP using either a 12 mm AirSeal valve-less Trocar (n=19 [14 t-RARP/5 e-RARP]) or a 12 mm Versaport Plus V2 Trocar (n=17 [11 t-RARP/6 e-RARP]) were prospectively evaluated. Age, body mass index, tumor characteristics, and surgical approach were similar in both cohorts. Besides relevant clinical data, episodes of pressure loss (<8 mm Hg), the number of necessary trocar manipulations, the frequency of camera cleaning, and overall carbon dioxide (CO2) consumption were recorded and compared. Results: Mean surgical time was 175 minutes in the AirSeal and 166 minutes in the Versaport group (p=0.55). Whereas in the AirSeal group, only one episode of pressure loss <8 mm Hg was observed...
